One parent has the blood type A and the other blood type B. What are the genotypes of the parents if they produce children with only blood type AB?

Answers

Human blood type is determined by co-dominant alleles. An allele is one of several different forms of genetic information that is present in our DNA at a specific location on a specific chromosome. There are three different alleles for human blood type, known as IA, IB, and i. For simplicity, we can call these alleles A (for IA), B (for IB), and O (for i).

Each of us has two ABO blood type alleles, because we each inherit one blood type allele from our biological mother and one from our biological father. A description of the pair of alleles in our DNA is called the genotype. Since there are three different alleles, there are a total of six different genotypes at the human ABO genetic locus. The different possible genotypes are AA, AO, BB, BO, AB, and OO.

How are blood types related to the six genotypes?

A blood test is used to determine whether the A and/or B characteristics are present in a blood sample. It is not possible to determine the exact genotype from a blood test result of either type A or type B. If someone has blood type A, they must have at least one copy of the A allele, but they could have two copies. Their genotype is either AA or AO. Similarly, someone who is blood type B could have a genotype of either BB or BO.

A blood test of either type AB or type O is more informative. Someone with blood type AB must have both the A and B alleles. The genotype must be AB. Someone with blood type O has neither the A nor the B allele. The genotype must be OO.

How are ABO alleles inherited by our children?

Each biological parent donates one of their two ABO alleles to their child. A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. This couple could have children of either blood type A (O from mother and A from father) or blood type B (O from mother and B from father).

Since there are 4 different maternal blood types and 4 different paternal blood types possible, there are 16 differnt combinations to consider when predicting the blood type of children. In the tables below, all 16 possible combinations are shown. If you know the blood type of the mother and father, the possible blood types for their children can be found.

What about the Rh factor? Can a father of blood type A+ have a child who is blood type A-?

The Rh factor genetic information is also inherited from our parents, but it is inherited independently of the ABO blood type alleles. There are 2 different alleles for the Rh factor known as Rh+ and Rh-. Someone who is "Rh positive" or "Rh+" has at least one Rh+ allele, but could have two. Their genotype could be either Rh+/Rh+ or Rh+/Rh-. Someone who Rh- has a genotype of Rh-/Rh-.

Just like the ABO alleles, each biological parent donates one of their two Rh alleles to their child. A mother who is Rh- can only pass an Rh- allele to her son or daughter. A father who is Rh+ could pass either an Rh+ or Rh- allele to his son or daughter. This couple could have Rh+ children (Rh- from mother and Rh+ from father) or Rh- children (Rh- from mother and Rh- from father).

5.can there be tissues,organs and systems without cells? support your answer._____________ ​

Answers

1- The building block of nature, or life really are cells.
2- No, because some unicellular organisms like bacteria only consist of 1 cell.
3- An example is bacteria, amoeba, etc.
4- Multicellular organism consist of different cells and mostly have different specialized cells. Unicellular organisms carry out their functions like multicellular, but all in 1 cell. They are known to be smaller than multicellular organisms.
5- No, because cells are the building blocks of life and you need cells to form together to form tissues, later into organs and organ systems. Tissues and organs function due to the amount of cells functioning. Tissues and organs are the formation of cells that serve a function to create more complex systems.

Which of the following landforms is not made by groundwater erosion?

A. stalactites

B. stalagmites

C. mountains

D. sinkholes

Answers

Answer:

mountains?

Explanation:

Answer: Mountains

Explanation: Groundwater erodes rock beneath the ground surface, especially carbonate rock. Groundwater deposits material in caves to create stalactites, stalagmites, and columns. And we know that a sink whole is also known as a cenote, sink, sink-hole, swallet, swallow hole, or doline, is a depression or hole in the ground caused by some form of collapse of the surface layer. Most are caused by karst processes – the chemical dissolution of carbonate rocks or suffosion processes

Why is a feather non living? Give detailed explanation. Thanks

Answer:

feathers are dead tissues. They are only alive while developing as they have a blood supply. Feathers are produced by living cells located in small pit-like follicles in a bird's epidermis, its outer skin layer. The feather is enlarged by the keratin that is protruding straight out from the skin follicle. In order for something to be classified as anything that was never alive

Explanation:

feathers are non-living because theyre dead tissues. theyre produced by living cells in a bird epidermis and as it reaches full size, the blood supply is cut off and the feather is fully functional but non-living

Concerns about soil management are not the same in all climates. Suppose you own a farm in the state of Washington, where there is a lot of rain throughout the year. Which two issues would be of major concern in managing the soil on your farm?

Answers

Answer:

Soil Erosion

With so much rain coming all year, soil erosion will definitely be a problem if not handled. The splashing of the water on the soil and the subsequent runoff will increase soil erosion. Your farm will lose soil if this is not stemmed and losing soil can lead to a number of negative consequences.

Loss of Nutrients.

One such effect of soil erosion which will be another major concern is the loss of nutrients. This happens when the structure of the soil is broken down by the erosion and the various nutrients in the soil will be carried off as the rain moves away and lost to your farm.
