part 1

If a parent is heterozygous for a gene, 1/2 of the time they
will contribute a dominant allele to their offspring and 1/2 of the
time they will contribute a recessive allele to their offspring.
The phenotypes of the resulting offspring will be _____ dominant
and _____ recessive.

Multiple Choice

1/4; 3/4

1/2; 1/2

all (4/4); no (0/4)

3/4; 1/4

Part 2

The probability of having an offspring with both the dominant
phenotypes for both genes is equal to the product of the individual
probabilities. This means, the probability of having a dominant
phenotype for both traits would be

Multiple Choice

4/4 x 4/4 = 16/16.

3/4 x 1/4 = 3/16.

1/2 x 1/2 = 1/4.

3/4 x 3/4 = 9/16.

Part 3

Select all of the following ways in which meiosis II is
different than meiosis I.

Multiple Choice

Interkinesis does not involve the replication of chromosomes,
whereas interphase does.

Crossing-over does not occur in prophase II, whereas it does
occur in prophase I.

Cells in meiosis II are haploid and cells in meiosis I are
diploid.

Sister chromatids separate in anaphase II, whereas homologous
chromosomes separate in anaphase I.

All of the answer choices are correct.
