Multiple Choice

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?

Has a video solution.

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: ___________

Textbook Question

In garden peas, yellow seeds (Y) are dominant to green seeds (y), and inflated pods (I) are dominant to constricted pods (i). Suppose you have crossed YYII parents with yyii parents. List the genotype(s) of gametes produced by F1 individuals.

Textbook Question

In garden peas, yellow seeds (Y) are dominant to green seeds (y), and inflated pods (I) are dominant to constricted pods (i). Suppose you have crossed YYII parents with yyii parents. Draw the F2 Punnett square. Based on this Punnett square, predict the expected phenotype(s) in the F2 generation and the expected frequency of each phenotype.

Textbook Question

In tigers, a recessive allele of a particular gene causes both an absence of fur pigmentation (a white tiger) and a cross-eyed condition. If two phenotypically normal tigers that are heterozygous at this locus are mated, what percentage of their offspring will be cross-eyed? What percentage of cross-eyed tigers will be white?
