Enter your answer as the number of flies of each phenotype separated by a colon (example: 100:300:100:300).
Answer:
Part A:
2. wild type (m+g+/mg)
4. miniature wings, garnet eyes (mg/mg)
Part B:
32:368:368:32
Explanation:
When calculating the recombination frequency, we need to know that 1% of recombinations = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.
The map unit is the distance between the pair of genes for which every 100 meiotic products, only one results in a recombinant one.
So, en the exposed example:
PART A:
First, we need to Identify the gametes for the individual with the genotype m + g / mg + and label parental and recombinants
Gametes:
m+ g parental type m g+ parental type m+ g+ recombinant typem g recombinant typeKnowing that the only possible gamete type for the other parental is mg, then we can identify the phenotypic classes of the offspring that were generated as a result of a crossover event. These would be
2. wild type (m+g+/mg)
4. miniature wings, garnet eyes (mg/mg)
PART B:
We know that the total number of individuals equals 800.We also know that the distance between genes equals 8 MU.To calculate the number of the phenotypes among the offsprings,
8 map units = 8% of recombination in total
= 8/2% m+g+/mg + 8/2% mg/mg
= 4% + 4%
The recombination frequency of m+g+/mg equals 0.04
The recombination frequency of mg/mg equals 0.04.
100% - 8% = 92% of parental in total =
= 92/2% of m+ g/mg + 92/2% m g+/mg
= 46% + 46%
The recombination frequency of m+g/mg equals 0.46
The recombination frequency of mg+/mg equals 0.46.
The frequency for each ggenotype is:
F (m+g+/mg) = 0.04 F (mg/mg) = 0.04. F (m+g/mg) = 0.46 F (mg+/mg) = 0.46.The number of individuals with each genotype is:
m+g+/mg = 0.04 x 800 = 32mg/mg = 0.04 x 800 = 32m+g/mg = 0.46 x 800 = 368m g+/mg = 0.46 x 800 = 36832 wild type : 368 miniature wings : 368 garnet eyes : 32 miniature wings, garnet eyes

A diagram of meiosis I is shown below.
At which stage of meiosis I does the exchange in genetic material between homologous chromosomes result in recombinant chromosomes?
prophase I
metaphase I
anaphase I
telophase I
Answer:
The correct answer is - prophase I
Explanation:
Crossing over or recombination is the event that takes place during the pachytene stage of Prophase I of Meiosis I. During this event, the exchange in genetic material between non-sister chromatids of homologous chromosomes results in the recombination of the genetic material or recombinant chromosome.
Prophase I is the first stage which is characterized by the condensation of the chromosome and form tetrad and appeared to be X like structure in the cell and followed by the crossing over or genetic exchange of homologous chromosomes.
Which processes produce the carbon dioxide from the original glucose molecule? Which processes do NOT produce CO2 molecules? (this is abt cell respiration)
The process that is responsible for the production of carbon dioxide from the original glucose molecule is known as Cellular respiration.
What is Cellular respiration?Cellular respiration may be defined as a biological process through which a form of sugar which is known as Glucose is transferred into energy in the form of ATP in the presence of oxygen. This energy is required to accomplish metabolic activities.
The complete reaction of cellular respiration is as follows:
Glucose + Oxygen → Carbon dioxide + Water + Energy (ATP).The process that does not produce carbon dioxide molecules is the oxidation of food during respiration. In other words, it is known as Lactate fermentation. Lactate fermentation initiates with glycolysis and forms lactate.
Therefore, the process that produces carbon dioxide and the process that does not produce carbon dioxide is well described above.

They are both made of one or more cells.
Explanation:
A plant and an animal are both living things. According to the Cell Theory, what we can conclude about these two very different organisms is that they are both made of one or more cells.
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Generally, cells have the ability to independently replicate themselves.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles and they include nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, etc.

A(n)
bond forms between a hydrogen atom with a partial positive charge on one
molecule and another atom, such as oxygen, with a partial negative charge on an adjacent molecule.
Answer:
Due to difference in the values of electronegativities.
Explanation:
A covalent bond is formed between hydrogen atom with a partial positive charge on it and another atom, such as oxygen, have a partial negative charge on an adjacent molecule. This is because of the difference in the values of electronegativities. The hydrogen atom has lower electronegativity value as compared to oxygen so the shared pair of electron is slightly attracted by oxygen atom towards itself and formed partial positive charge on hydrogen and partial negative charge on oxygen atom.

This question may be completed independently or as a group exercise. You have learned that humans have 46 total chromosomes, and chimpanzees have 48 total chromosomes. Use other textbooks in biological anthropology and biology (or reputable online resources) to find the number of chromosomes in other organisms. Give an organism with considerably more chromosomes than humans. Give an organism with considerably fewer chromosomes than humans. Did your findings surprise you
Answer:
In comparison to humans, there are more chromosomes in the Hermit crab that is 127 pairs of chromosomes for a grand total of 254 and in Myrmecia pilosula has fewer chromosomes than humans.
The complexity of an organism or how advance is an organism has nothing to do with the number of chromosomes it had. The chromosome number is subject to change over time. Human ancestors had more chromosome numbers as compared to now but they are not advanced to us.

what is the base-pair rule for a DNA strand matching an RNA strand?
Explanation:
The base pairing of guanine (G) and cytosine (C) is just the same in DNA and RNA. So in RNA the important base pairs are: adenine (A) pairs with uracil (U); Guanine G() pairs with cytosine (C).
The Chargaff rule only holds true for DNA. Base pairing doesn't take place since RNA is single-stranded. Consider a DNA strand.
What make base pair unique in DNA and RNA?Compare the two DNA strands' base-pair rules to this one. Since uracil is absent from DNA, T and A complement one another. In contrast, T bonds with A and A bonds with U in a DNA/RNA match.
Important: It serves as the foundation for base pairing. This rule can be used to both determine the DNA strand length and if a base is present in the molecule.
Adenine and thymine are always equal, and cytosine and guanine are also always equal, allowing us to calculate the percentages of each base.
It assists in figuring out the makeup and structure of DNA in various species. It is constant within a species.
Therefore, the base-pair rule for a DNA strand matching an RNA strand.

Synthetic biologists at the Scripps Institute expanded the genetic repertoire by adding two new bases into living bacterial cells. The two bases are named d5SICS and dNaM, and they base-pair with one another. How many different codons are possible in nucleic acids containing six different nucleotides if a codon consists of a consecutive sequence of three nucleotides
Answer:
216 codons
Explanation:
In the RNA molecule there are four types of nucleotide bases, i.e., Adenine, Uracil (Thymine in DNA), Guanine, and Cytosine. In consequence, the number of possible codons or combinations of nucleotide triplets is 64 (4³ = 64 codons). However, these 64 codons code for only 20 different amino acids because multiple codons can code for the same amino acid, it is for that reason that the genetic code is redundant. In this case, if the number of bases would be six (6) instead of four (4) bases, then the number of possible combinations of nucleotide triplets would be 216 codons (6³ = 216).
