Hello everyone, in this question we have been said that we are studying the two mendelian traits in mice that is the body color as well as the tail shape.
00:12
So the allele for the yellow body is dominant over the allele which is grey.
00:19
So and the allele for the straight tail is dominant over the allele for the curved tail.
00:31
So the mouse 1 has the homozygous dominant allele for body color and tail shape that means yy, s and s and the mouse 2 has the homozygous receptive allele for the body color as well as the tail shape.
00:53
So this here is basically the parental cross and we have been asked that what is the body color genotype for each mouse.
01:02
So here this is the mouse 1 which has the dominant body.
01:08
So here there is yellow color body and straight tail is present.
01:15
This here is mouse 2 in which the grey color and curved tail is present.
01:25
Then we have been asked that what is the tail shape genotype for each mouse.
01:32
So basically this is blank 1 this one and this here is blank 2.
01:41
Now for blank 3 we will write that the mouse 1 has the dominant condition.
01:50
Sorry in the blank 1 so basically here in the blank 1 we had been asked only about the body color genotype.
02:00
So here mouse 1 has yy and the mouse 2 here has yy.
02:11
Then we have been asked about the tail shape.
02:16
So here in blank 3 the mouse has the straight tail so that is ss and in the blank 4 the mouse 2 has the receptive condition that is the curved tail and then we have been asked if we cross mouse 1 and mouse 2 what will be the offspring genotype obtained.
02:38
So here the f1 generation will have the heterozygous condition but the phenotype will be yellow and straight...
