Answer #1

Why F1 is RrVv, I have drawn the punnet square to understand that.

R>r means R is dominant over r.

Let ded exes be R and while excl be r (R ) Red eyes - RR, Rr. While eyes = a. Lef Normal wings se vand wesligial wings se o .Now, the parents genotype:

For RrVv to happen, there must be both dominant and recessive genes. This genotype is achieved generally when pure breed is used.

So P1 will be RRVV and P2 will be rrvv.

So, RRVV * rrvv ----> RrVv

    A female fruit fly with vermilion eyes and normal wings is crossed to a male with normal red eyes and cut wings. The F1 progeny consist of females with red eyes and normal wings, and males with vermilion eyes and normal wings. When the F1 progeny are interbred, the F2 consists of two types of females vermilion eyes, normal wings (1/2) and red eyes, normal wings (12), and two types of males-vermilion eyes, normal wings (12) and red eyes, cut...

    If an apterous female fruit fly with wild type (+) red eyes is crossed with a white eyed male with normal wild type wings, what is the resting F1 generation? Please show on a punnet square.Also what is the punnet dihybrid cross for the F2 generation. Note: the recessive white eyed allele is X-linked while the apterous (wingless) recessive allele is NOT x-linked. SO to summarize: male with recessive white eyes and with normal wild type wings and a recessive...

    B. Geneticists have discovered that some flies have white eyes and others red eyes. The difference in eye color is due to inheritance of one gene. Two true-breeding flies are mated, with the female white-eyed and the male red-eyed. The F1 are 1/2 red eyed and female, and 12 white-eyed and male. (There are no white-eyed females, or red- eyed males.) 11. The F2 includes: 54 red-eye females 42 white-eyed females 48 red-eyed males 56 white-eyed males Phenotypes d (o-edd/e...
