Question

Please Please someone help!!!!
Mary has type A blood and her husband has type B blood. Her husband’s parents both had type AB. They have three children, one with type A, one with type AB, and one with type B. Relatives suspect that one of the children was adopted.

a. What are the parent’s blood genotypes?




b. Which child was adopted? Explain your answer.

Answer 1

People who have an AA genotype are said to have type A blood because the agglutinogen on their red blood cells has the enzyme activity associated with the A allele. Likewise, people with the BB and the BO genotypes are said to have type B blood. People who have the AB genotype have the enzyme activity associated with both the A and B alleles. These people have no agglutinins in their blood plasma

Answer 2

The concepts of genotype and phenotype can be easily understood in the case of blood type. Genotype refers the actual genes an individual possesses that determine a particular trait. Phenotype refers to the characteristics of that trait an individual displays. In the case of blood type, both the AA and AO genotypes cause individuals to display the A blood type phenotype. Similarly, both the BB and BO genotypes cause individuals to display the B blood type phenotype. Individuals who are phenotypically type O or type AB have only one possible genotype, OO and AB, respectively.

Answer 3

Your welcome. Did that make since, cus I tried really hard for it to make since

Answer 4

well type A and B blood is phenotype and type AB blood is genotype, So therefore I think the Child with the AB blood type is the adopted one.

Why do you think it's the child with the A blood type? I would like too see what your getting at?

Answer 5

Nvm I see now, I read the top thing I posted about People who have the AB genotype have the enzyme activity associated with both the A and B alleles. So I think your right missy. the child with the A blood type is adopted :) Godd Job

Answer 6

Your welcome. I love science. Especially Biology.
