AP Biology Unit 5 Review Quiz

Suppose that in sheep, a dominant allele (B) produce black hair and a recessive allele (b) produce white hair. If you saw a black sheep, you would be able to identify

• its phenotype for hair color
• its genotype for hair color
• the genotype of only one of its parents
• the phenotype of both of its parents

One of the main reasons genes assort independent of one another  is that 

• they produce unrelated traits
• they produce related traits
• they are on the same chromosome
• they are on different chromosomes.

A single gene has 3 or more alternative forms. These are called

• heterozygotes
• multiple alleles
• epistatic
• polygenic

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

In humans, if a non-disjunction event leads to an individual that is XXY, they would

• be female because they have 2 X chromosomes
• be male because they have a Y chromosome
• not survive
• have both male and female characteristics

Chromosomes that do NOT play a role in determining the sex of an individual are called

• sex chromosoems
• X and Y
• autosomes
• A and B are correct

In a sex-linked inheritance pedigree you would expect to see

• more affected females
• all carrier males
• more affected males
• an equal number of affected males and females
