Meiosis, Genetics, Heredity REVIEW

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 can sometimes assort independently of one another is that 

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

If a single gene has 3 or more alternative forms, these are called:

• heterozygotes
• multiple alleles
• epistatic
• polygenic

A child has type O blood, if mother has type A blood, what would the fathers blood type be

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

In mice, the homozygous mice are black or white. The heterozygous mice are gray. What pattern of inheritance is expressed in fur color in mice?

• complete dominance and recessiveness
• co-dominance
• incomplete dominance
• pleiotropy

If the parents of a cross are AaBcCc x aaBBcc. What is the probability of an offspring that is homozygous recessive for all 3 traits?

• 1/64
• 1/32
• 1/8
• O

Red x white = pink
What is the genotype of the pink flower?

• RR
• rr
• Rr
• Can't be determined

Blood type AB

• epistasis
• codominance
• incomplete dominance
• hybrid vigor

A child born with blood type O could have parents with all of the following blood types except...?

• A and B
• A and O
• A and A
• AB and O

In the second generation-how many people have the disease?

• 2
• 4
• 6
• 8
