Answer:
a) Parents Genotype should be (CC,Vv) and (cc,VV).
b) The genotypes of the parents are (Cc,Vv) and (Cc,Vv).
c) The genotypes of the parents are (Cc,Vv) and (cc,vv).
Explanation:
<h2> (<u>a)</u> </h2>
Mating has occured between a normal colored mice whose genotype is C_,V_ and normal white mice with genotype cc,V_. The offsprings are as follows :
1) normal mice produced 29 colored
2) 10 colored, waltzing progeny.
Thus all offspring are normal. The genotype of the first parent should therefore be CC. Waltzing trait is produced. The V gene should therefore be heterozygous in both traits.
Hence The parent genotypes should be<u> (CC,Vv) and (cc,CV).</u>
<h2> (b)</h2>
In this case the approximate ratio in which the descendants are produced is 9:3:3:1. Hence genotypes of the parents are <u>(Cc,Vv) and (Cc,Vv).
</u>
<h2>
(<u>
c)</u> </h2>
In this case the approximate ratio in which the offsprings are produced is 1:1:1. The genotypes of the parents are <u>(Cc,Vv) and (cc,vv).
</u>
