Blue flower is dominant to yellow flower. Tall plant is dominant to short. Cross BbTt * BbTt. What precenetage of the offsprings are expected to be heterozygous for both traits?

Answers

Answer 1

Answer:

The correct answer would be - 25%.

Explanation:

It is given that the Blue flower is dominant over the yellow flower which means Blue is represented by allele B here and allele b for yellow and Bb is a heterozygous case with a blue phenotypic character. Similarly, the Tall plant is dominant over short and represented by T and t respectively.

BbTt is a heterozygous condition and a cross with itself will produce :

Gametes: BT Bt bT and bt

          BT       Bt       bT       bt

BT     BBTT   BBTt   BbTT   BbTt

Bt      BBTt    BBtt    BbTt   Bbtt

bT     BbTT   BbTt    bbTT   bbTt

bt      BbTt     Bbtt    bbTt     bbtt

Here 4 out of 16 offspring are heterozygous for both traits represented by bold alphabets. Therefore the correct answer is 25%

Answers

Answer:

The population of peppered moths thrived, because they camouflaged with the bark of the trees, thereby they were not easily seen by predators. Black moths were easily seen by predators and they were eaten as a result. Because the black moths did not survive, they were unable to reproduce offspring with those traits. However, peppered moths were able to reproduce offspring that were also peppered. During the industrial revolution, the colour of the bark darkened. This meant the peppered moths were easily seen by predators, so they were eaten. Black moths camouflaged with the bark, so now they weren't easily seen by predators. Now that the black moths survived, they could reproduce more black moths. But peppered moths weren't able to reproduce more peppered moths because most didn't survive. This is an example of how an abiotic factor, such as bark can affect a population of a species. Because the bark influenced the survival of the moths, some moths with the desirable traits survived, and others with the undesirable traits died.

Movement of chromosome segment to a non-homologous chromosome. This type of chromosomal mutation occurs when one chromosome swaps genetic information with a different chromosome (this is NOT Crossing Over). O Inversion O Duplication O Deletion O Translocation​

Answers

Answer:

The correct answer is ''Translocation​.''  

Explanation:

Translocation is a chromosomal abnormality that is due to a change in position of a chromosomal segment to another non-homologous chromosome of the same nucleus or to another part of it. It is produced by the exchange of segments between two chromosomes without loss of genetic material is called reciprocal or balanced translocation, when it gives rise to monocentric chromosomes.Translocations can be detected cytologically because the structural heterozygote forms a quadrivalent (4-chromosome association) in meiotic prophase. Sometimes they can also be detected by changes in the size of the chromosomes if the exchanged segments are of different lengths.
