In humans brown eye color is dominant to blue eye color. Suppose that your mother is homozygous and your father is heterozygous and you have brown eyes. If you have a child with blue eyes, what is your genotype?
Determine the genotypes of the parents if the father is blood type A, the mother is blood type B, the daughter is blood type O, one son is blood type AB, and the other son is blood type B
show a cross between a woman with blood type o and a man who is heterozygous blood type b. Using mendels rules. What is the percent chance that the child has blood type o?
