In Andalusian fowls, black individuals (BB) and white individuals (bb) are homozygous. Heterozygous individuals are grey (Bb).  
What is the genotype ratio for a cross between a grey fowl and a white fowl?

• 2 BB: 2 Bb: 0 bb
• 0 BB: 4 Bb: 0 bb
• 0 BB: 2 Bb: 2 b
• 1 BB: 2 Bb: 1 bb

In rabbits, there are four different versions of the gene for coat color. What pattern of inheritance is this?

• incomplete dominance
• co-dominance
• polygenic inheritance
• multiple alleles

In which situation does the environment play a significant role in gene expression?

• An Arctic fox has a gray coat in summer and a thick, white coat in winter.
• Two pea plants with yellow seeds produce some offspring with green seeds.
• A cross between red flowers and yellow flowers produces offspring with orange flowers.
• None of the other answers are correct.

There are genetic crosses in which neither of two alleles is dominant over the other. In these crosses, the phenotype is a blend of the two alleles. These crosses are described as   

• Codominant
• Incomplete dominance
• Polygenic inheritance
• Multiple alleles

• A or B only
• AB only
• A, B, AB only
• A, B, AB, or O

If a woman is a carrier for a sex linked recessive trait of hemophilia and her husband has hemophilia, which of the following is true? Make a punnett square!

• all daughters will have hemophilia
• 50% of daughters and 50% of sons have hemophilia
• 100% of sons have hemophilia and 100% of daughters are carriers

The Punnett square shown here shows two of the possible offspring from a cross between two individuals for a simple autosomal trait where (A) is the dominant allele and (a) is the recessive allele. The offspring in boxes 1 and 2 will have what genotypes?

• 1 is AA and 2 is aa.
• Both 1 and 2 are Aa.
• 1 is Aa and 2 is aa.
• It is not possible to determine the genotypes.
