A rabbit rancher reports that a single male rabbit among a litter is observed to have an unusual fur texture that would be a valuable source for garments. He asks your advice on how to raise more rabbits like this. You know which animals are his parents, neither of which have this fur texture. Choose a major mode of Mendelian inheritance and then describe which genetic crosses you could perform using this rabbit to maximize the percentage of offspring with the unusual fur phenotype.

Solution

According to Mendel work just two allels existed for each gene.In a population multiple alleles may exist and different organisms possess different pairs of the alleles.

In case of rabbit fur texture,  consider a gene that specifies coat color in rabbits, called the CCC gene. The CCC gene classified into four common alleles as, C, c^ch, c^h and c.

Multiple alleles can make many possible dominance relationships. here, the black CC allele is dominant for all the others.c^chc^ch allele is incompletely dominant to c^{h and} c rabbit. The c^h rabbit is dominant to c.

So, If offspring is all black then the mother is homozygous black and if half of them are black and brown then it means female is heterozygous black.

therefore, rabbit rancher can find out these relationships by crossing different rabbits of different genotypes and can observe the phenotypes of the heterozygous raabit kits.

Ranchers can proceed as, In case of dominant colour i.e if the female is homozygous then the cross should be carried out with dominant and recessive traits as, CC x cc, this will leads to production of all black colour rabits whereas if the female is heterozygous then the should be carried out with cc x Cc, this will leads to production of 50% black and 50% white colour rabbits.
