Question

activity: beyond dominant and recessive
inant and recessive
in rabbits, coat color
is determined by one
gene with at least 4
different alleles. the
table shows the
phenotypes for
pairings of alleles.

1. what is the order

of dominance of the
4 alleles?
type your answer
full color: $cc$, $cc^{ch}$, $cc^h$, or $cc$
chinchilla: $c^{ch}c^h$, $c^{ch}c^{ch}$, or $c^{ch}c$
himalayan: $c^hc$ or $c^hc^h$
albino: $cc$

Explanation:

1. Full color (allele $C$) is expressed when paired with $c^{ch}$, $c^h$, or $c$, so it is the most dominant.
2. Chinchilla (allele $c^{ch}$) is expressed when paired with $c^h$ or $c$, but not when paired with $C$, so it is next in dominance.
3. Himalayan (allele $c^h$) is expressed when paired with $c$, but not when paired with $C$ or $c^{ch}$, so it is more dominant than $c$.
4. Albino (allele $c$) is only expressed when homozygous ($cc$), so it is the least dominant.

Answer:

$C > c^{ch} > c^h > c$
