  A heterozygote with a dominant and a recessive allele will have the dominant phenotype. In Mary's case, this will manifest itself in her brown eyes. A homozygote with two dominant alleles will have the dominant phenotype, so John also has brown eyes. To have blue eyes, the children would have to inherit two alleles for blue eyes.

Answer to Question 1

Ans:
A

Feedback:

A heterozygote with a dominant and a recessive allele will have the dominant phenotype. In Mary's case, this will manifest itself in her brown eyes. A homozygote with two dominant alleles will have the dominant phenotype, so John also has brown eyes. To have blue eyes, the children would have to inherit two alleles for blue eyes. Because they will inherit, at most, one recessive allele for blue eyes, the children's eyes will be brown.

Answer to Question 2

Ans:
A, B, C

Feedback:

Klinefelter syndrome is characterized by breast enlargement, sparse facial and body hair, small testes, and inability to produce sperm. At puberty, testes do not respond to stimulation from gonadotropins and undergo degeneration. This leads to a tall stature with abnormal body proportions. Although the intellect usually is normal, most 47, XXY males have some language impairment.
