Genetics Review Quiz

The difference between Mendel's Law of segregation and his Law of independent assortment is the Law of (a)   is defined as each individual has two alleles for each gene, which segregate during meiosis, resulting in gametes that carry only one allele for any inherited trait, while the Law of ​ (b)   is defined as alleles of different genes separate independently of one another during the formation of gametes.

• segregation
• dominance
• hybridization
• independent assortment

What does a Punnett square show?

In genetics, a (a)   trait will only show if the individual has two copies of the recessive allele, whereas a (b)   trait will show even if the individual has only one copy of the allele, however if the individual only has one copy of the allele, then they are also a ​ (c)   for that trait.

• recessive
• dominant
• incomplete

• codominant

• unexpressed

• carrier

In cats, the gene for black fur (D) is dominant to the gene for grey fur (d). If two heterozygous cats have kittens, ​ (a)   are expected to be black and ​ (b)   are expected to be grey.
