In the fruit fly Drosophila melanogaster, wild type eye color is a brick red color and is produced by the action of two genes, one producing red color, the other brown. Vermilion is an X-linked recessive mutation that results in a bright red eye. Brown is an autosomal recessive mutation that results in a brown eye. Flies carrying both the vermilion and brown mutations produce no pigment and have white eyes. True breeding Vermilion eyed females are crossed to brown eyed males

a. Determine the genotype of the parental flies

b. Diagram the cross and determine the F1 genotypic and phenotypic ratios

c. Diagram the cross when the F1 progeny are mated to produce an F2 generation. Determine the F2 genotypic and phenotypic ratios. You must correctly use the forked line method (branch diagram).

4) In fruit fly (Drosophila melanogaster), grayish eye color and wingless bodies are caused by recessive genes located on different chromosomes. Red eyes (gr+) and normal wings (wl+) are dominant to gray eyes (gr) and wingless (wl), respectively. Suppose that a true-breeding male with gray eyes and normal wings is crossed with a true-breeding female with red eyes and wingless. a) What is the genotype and phenotype of the F1? b) If these F1 individuals were allowed to intermate, what...

In the fruit fly, Drosophila melanogaster, a wingless female fly is mated to a male that is white-bodied and legless. Assume that all alleles causing these phenotypes are recessive. Phenotypically wild-type F1 female progeny were mated to fully homozygous (mutant) males, and the following progeny were observed: Phenotypes Number Observed wingless 324 wild-type 34 white, wingless 135 white 8 white, legless 319 hairless, white, legless 32 hairless 140 hairless, legless 9 (a) With respect to the three genes mentioned in the problem, what are the genotypes...

In the fruit fly, Drosophila melanogaster, a spineless (sp, no wing bristles) female fly is mated to a male that is claret (cl, dark eyes) and hairless (h, no thoracic bristles). Phenotypically wild type F1 female progeny were mated to fully homozygous (mutant) males and the following progeny (1000 total) were observed. PHENOTYPES NUMBER OBSERVED spineless 316 wild 8 claret, spineless 136 claret 37 claret, hairless 304 hairless, claret, spineless 12 hairless 144 hairless, spineless 43 What is the correct gene map for these genes?...

Use the preamble below to answer Questions 27 and 28 In the fruit fly Drosophila melanogaster, red eye colour (R) is dominant to white eye colour (r). A student wishes to perform a test cross to determine whether a female red eyed fruit fly is homozygous or heterozygous for the eye colour. The student mates the female fruit fly with a red eye coloured male and studies the offspring, which are 100% red eye. The student concludes that the genotype...

The entire genome of the fruit fly Drosophila melanogaster consists of 1.65 x 108 base pairs (bp). If this organism’s DNA polymerase can copy DNA at the rate of 30 bp/sec calculate the minimum time (in days) required to replicate the entire genome. Remember there are 2 strands, and each are copied at the same time. 9,900,000,000 days 4,950,000,000 days 31.83 days 1909.7 days

In Drosophila the gene for red eyes is dominant over the gene cinnabar eye color, the gene for gray body color over the genome of the black color of the body, the gene for normal wings – on the genome of rudimentary wings. All the genes are on the same chromosome. After crossing a homozygous female Drosophila with red eyes (cn+), gray body (b+) and normal wings (vg+) with a homozygous recessive male with cinnabar eyes (cn), black body (b)...

In Drosophila the recessive alleles for white eyes is X-linked (normal eye color is red) and...

In Drosophila the recessive alleles for white eyes is X-linked (normal eye color is red) and the recessive allele for vestigial wings is autosomal. A female heterozygous for both of these traits is crossed with a white-eyed vestigial male. What proportion of the FEMALE progeny will be white-eyed with vestigial wings.? (a) 100 % (b) 75 % (c) 50 % (d) 25 % (e) 0 %

32) Normal (wild-type) Drosophila eyes are red. In a cross in Drosophila involving the X-linked recessive eye mutation white (resulting in a white eye) and the autosomal recessive eye mutation sepia (resulting in a dark eye), predict the sex and color of the eyes of the offspring from crossing true-breeding parents for parts A) and B) below. White is epistatic to the expression of sepia (i.e., if an eye is white, it cannot also be sepia; i.e., white masks the...
