Question
2. 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.
Mode of Inheritance Chosen: ___________________________________
Explanation / Answer
Q) The mode of inheritance choosen in the question is incomplete dominance , it is a deviation to the mendel's law of Dominance, here neither of the parents have this fur texture.
Incomplete dominance is a genetic cross between two individuals having two variety of phenotypes producing an offspring that has a different phenotype, the offspring is usually a blend of both the phenotypes. here the two genes of parents are not related as dominant or recessive, but each of them expresses themselves partially. The phenotypic ratio is 1:2:1 in F2 generation.
This method can be used to increase the percentage of offspring with the unusual fur phenotype.
