Question

beyond dominant and recessive 3. a breeder crosses two himalayan rabbits and to her surprise one of their offspring is an albino. what would be the genotype of the parents? 4. if you breed a black full color rabbit with any other rabbit shown in this chart, what color will the offspring display? full color: ( cc ), ( cc^{ch} ), ( cc^{h} ), or ( cc ) chinchilla: ( c^{ch}c^{ch} ), ( c^{ch}c^{h} ), or ( c^{ch}c ) himalayan: ( c^{h}c^{h} ) or ( c^{h}c ) albino: ( cc )

Explanation:

Step1: Identify albino genotype

Albino rabbits have genotype $cc$, meaning they must inherit one $c$ allele from each parent.

Step2: Deduce parent genotypes

Himalayan rabbits have genotypes $c^hc$ or $c^hc^h$. For them to produce an albino offspring ($cc$), each parent must carry the recessive $c$ allele. So each parent must be $c^hc$.

Step1: Identify black full color genotype

Black full color rabbits have genotypes that include the dominant $C$ allele ($CC$, $Cc^{ch}$, $Cc^h$, or $Cc$). The $C$ allele is completely dominant over all other color alleles ($c^{ch}$, $c^h$, $c$).

Step2: Determine offspring phenotype

When a rabbit with a $C$ allele (black full color) breeds with any other rabbit, all offspring will inherit at least one $C$ allele, so they will display full (black) color.

Answer:

Each parent has the genotype $c^hc$
