What will be the result of crossing a first generation rabbit, diheterozygous with disheveled black
What will be the result of crossing a first generation rabbit, diheterozygous with disheveled black hair, with the same rabbits?
Since heterozygous individuals exhibit dominant traits in the phenotype, it should be concluded that black disheveled hair dominates in rabbits. Let’s say white smooth rabbit hair is a recessive trait.
Let the gene for the development of black hair in rabbits be K, then the gene for white hair will be k.
Let the gene for disheveled rabbit hair be L, then the gene for smooth hair is l.
KkLl diheterozygous rabbits are capable of producing four types of germ cells – KL, kl, Kl, kL.
The offspring when crossing such rabbits among themselves will be represented by the following options:
rabbits with disheveled black hair (4 KkLl, KKLL, 2KkLL, 2KKLl) – 56.25%;
rabbits with smooth black hair (2Kkll, KK ll) – 18.75%;
rabbits with smooth white hair (kkll) – 6.25%;
rabbits with disheveled white hair (kkLL, 2kkLl) – 18.75%.
