some traits have multiple alleles in a population. For example, ABO blood type has three Alleles: ________, _________, and ________, __________ and ___________ are codominant. If both parents are AB tye, what are the possible genotype of their children? ____________________________________________?

A cross between a parent with dominant phenotype (A) and a parent with recessive phenotype (a) is called a ______________ cross. It is used to find out the genotype of the dominant parnet. If all offspring have dominant phenotype, this parent's genotype should be _____________; if dominant to recessive is 1:1, this parent's femotype should be ___________?

Hemophilia is a __________________ disorder. Both parents are normal, their son has hemophilia. What is the mother's genotype? _______________. What is the father's genotype _________________? What is the son's genotype ________________? Her possible genotype should be __________ or ________?

Homework Answers

Answer #1

Three alleles - A,B and O allele.

A and B are codominant.

Possible blood group of children - A, B and AB.

Cross with dominant parent with recessive parent is called test cross.

If all are dominant then genotype of parent is AA.

If ratio of dominant to recesive is 1:1 then genotype is Aa.

Hemophilia is X linked recessive disorder.

If son has hemophilia then genotype of mother is XcX.

Father's genotype is XY.

Son's genotype is XcY.

Daughter's genotype should be XcX or XX.

Human ABO blood type is determined by three alleles (IA, IB, and i) whose gene products modify the H antigen produced by protein activity of an independently assorting H gene. A rare abnormality known as the “Bombay phenotype” is the result of epistatic interaction between the gene for the ABO blood group and the H gene. Individuals with the Bombay phenotype appear to have blood type O based on the inability of both anti-A antibody and anti-B antibody to detect...
