Which of the following is one of Mendel's three hypotheses for explaining his observations?

A) Adult plants always have traits that are governed by a single pair of alleles, but the number of possible alleles varies with each trait.
B) The pairs of alleles remain together in the formation of gametes so that each gamete gets both alleles.
C) Adult plants carry a trio of genes that will determine the inheritance of each allele.
D) If an adult plant has two different alleles, the alleles blend.

Suppose your mother has albinism, which is a recessive trait. Suppose also that your father has cystic fibrosis, which is also caused by a recessive trait. And, you learn that your father-in-law has albinism and cystic fibrosis. What are the odds that your first child will have both albinism and cystic fibrosis?

A) 1 in 2
B) 1 in 4
C) 1 in 8
D) 1 in 16
