2. A mutation in mice called short tail (st) causes defects in tail development. For the following 4 possibilities, indicate whether the males of the F1 will be ‘mutant’ or ‘normal’ and whether the females of the F1 will be ‘mutant’ or ‘normal’. You can assume that the male is the heterogametic sex (XY).

    In Drosophila, the autosomal recessive brown eye color mutation (b) displays interactions with both the X-linked recessive vermilion mutation (v) and the autosomal recessive scarlet (s) mutation. Flies homozygous for brown and simultaneously hemizygous or homozygous for vermilion have white eyes. Flies simultaneously homozygous for both the brown and scarlet mutations also have white eyes. Flies that are wildtype at all 3 loci have wildtype eye color. Flies that are homozygous or hemizygous for the recessive mutant at only one...

    In Drosophila, the X-linked recessive mutation vermilion (XV) causes bright red eyes, in contrast to the brick-red eyes of wild type (X+). Part A separate autosomal recessive mutation (br), causes the eyes to be brown. Predict the F1 results of the following cross: normal females x white males. (Assume that the parents are homozygous.) Flies carrying both mutations lose all pigmentation and are white-eyed. Label the diagram by dragging the labels to the appropriate targets. Note: not all labels will...

    In Drosophila, the X-linked recessive mutation vermillion (v) causes bright red eyes, in contrast to the brick-red eyes caused by the wild-type allele. A separate autosomal recessive mutation, brown (bw), causes flies to have brown eyes. Flies carrying both mutations have no eye pigmentation and are white-eyed. Determine the F1 and F2 phenotypic ratios for each sex from the following crosses: (a) brown females X vermillion males (b) white-eyed females X wild-type males

    A male mouse with a pale yellow coat called cream is mated to a female mouse with a wild-type gray- brown coat. All of the F1 mice, both males and females have the wild-type gray-brown color. One of these F1 female mice is mated to cream-colored male.              a. What are the expected results if cream is X-linked and recessive? What are the expected results if cream is autosomal and recessive? In fact, cream is X-linked. When the F1 female...

    scalloped (sd) is an X-linked recessive and ebony (e) is an autosomal recessive mutation. What proportion of scalloped, ebony females (relative to whole population) is expected in the F2 starting with a true breeding scalloped female which is wild type for ebony mating with a true breeding male mutant only for ebony. ANSWER: 1/16 PLEASE PROVIDE A WELL EXPLAINED ANSWER PLEASE!

    (1) A Drosophila male from a true-breeding stock with scabrous eyes and normal bristles was mated with a female from a true-breeding stock with normal eyes and javelin bristles. Both scabrous eyes and javelin bristles are autosomal recessive mutant traits. The F1 progeny all had normal eyes and normal bristles. F1 females from this cross were mated with males with both scabrous eyes and javelin bristles. a. Write all the possible phenotypic classes of the progeny that could be produced...

    1. In Drosophilia, females are XX, while males are XY. Yellow bodies are determined by an X-linked recessive mutation Xb, while the dominant wild-type allele XB produces brown bodies. A heterozygous female is crossed with a brown bodied male to produce the F1 generation. a) Among the F1 generation, what genotypes and phenotypes would be expected among the progeny, and in what proportion? b) from the F1 generation, males and females are mated at random. What genotypes and phenotypes would...

    In moths, males are homogametic. Spotted wings (s) are recessive to the wild-type and sex linked. A wild-type male is mated to a spotted female, and all the F1 are wild-type. If these F1 males are mated to F1 females, what will be the ratio of wild-type to spotted females in the F2?
