Codominance and multiple allele crosses

Question 1

what is co dominance

Answer 1

Codominance is a situation where two or more alleles are equally dominant. This means that if both alleles are present, they will both be observed.

Question 2

what is incomplete dominance

Answer 2

In complete dominance neither dominant allele is expressed individually, instead they blend

Question 3

what are multiple allele crosses

Answer 3

Multiple alleles are when there are more than two alleles for a particular characteristic.

Question 4

what is an example of co dominance and multiple allele crosses

Answer 4

blood groups

Question 5

what are the different blood groups alleles

Answer 5

IA = dominant blood group A
IB = dominant blood group B
i = recissive blood group O

Question 6

what are the different blood groups alleles

Answer 6

IA = dominant blood group A
IB = dominant blood group B
i = recissive blood group O

Question 7

A heterozygous man with blood group A marries a women with a heterozygous blood group B.

1. What are the genotype + phenotype ratios of their offspring
2. What are the chances of them having a girl with blood group A.
