1. For each of the following blood types, list the possible genotypes: Phenotype Possible Genotypes A B AB O 2. Dr. Paul is blood type O. His father was blood type A and his mother was blood type B. What were the genotypes of his parents? What are the possible blood types and phenotypic ratios expected for a cross involving these parental genotypes? 3.

what is b and c?
1) In marsh lizards rough scale (st) is completely dominant to smooth scale (s). Eye colour is determined by an incompletely dominant sex-linked allele and can be blue (b+), or yellow (b) with the heterozygote giving green eyes. A further gene (t) controls tail formation giving rise to a bent tail in homozygotes, t allele is dominant with respect to straight tail formation but is a recessive lethal. Parental genotypes of following phenotypes: A smooth,...

E)bacteria. 3) Which of the following is true according to Mendel's law of segregation? A)Each individual contains two alleles for each trait. B)Fertilization restores the presence of two alleles.

6. In humans, having a widow’s peak (W) is dominant to not having a widow’s peak (w). Sally has a widow’s peak. If Sally has a son who does not have a widow’s peak, what genotype can the father NOT be? 7. The ability to roll the tongue inward in humans is determined by the dominant gene T. From a couple both able to roll the tongue, a child is born. The child is unable to roll the tongue. What...

Assume red plumage is encoded by an autosomal dominant allele (R). You crossed a male robin with a red breast and a homozygous dominant genotype with a female robin with a homozygous recessive genotype. You get both male and female offspring, but find that only the male offspring have a red breast. How could you explain this? Group of answer choices a The red plumage has variable expressivity in males b The plumage gene is not present in females c...
