9. Patterns of Inheritance

A homozygous dominant male has a child with a heterozygous female. What is the probability that the child will have the same genotype as its father OR its mother?

A blue-eyed female that is homozygous recessive and a brown-eyed male that is heterozygous mate, producing two offspring. What is the probability that one child will have blue eyes AND one will have brown eyes? (Eye color is controlled by a single gene).

Mendel found that green pea pod color (y) was recessive to yellow pea pod color (Y). For the cross Yy × yy, what percentage of offspring are expected to be yellow?

What is the probability that a plant from a monohybrid cross of heterozygous parents, is homozygous dominant OR homozygous recessive?

A female dog with black fur (Ff) mates with a male dog that also has black fur (Ff). Determine the possible genotypes and phenotypes of their puppies using a Punnett Square. Black fur (F) is dominant to grey fur (f).

a) # of possible Genotypes:

FF: ________ 

Ff: ________ 

ff: _________

b) % of possible Phenotypes: 

Black fur: __________

Grey fur: ___________

Calculate the probability of 2 heterozygous (Rr) parents having 3 homozygous recessive (rr) offspring.
