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.

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...

A female fruit fly with singed bristles was mated with a male from a true-breeding wild-type stock with long bristles. All of the F1 females had wild-type long bristles and all of the F1 males had singed bristles. If the F1 flies are intercrossed, the expected ratio of long to singed bristles in the F2 flies is Multiple Choice 3:1 in both sexes. 3:1 in females, while all the males will have singed bristles. 1:1 in both sexes. 1:1 in...

A virgin Drosophila female whose thorax bristles are very short is mated with a males having normal (long) bristles. The F1 progeny are 1/3 short-bristle females, 1/3 long bristle females, and 1/3 long bristle males. A cross of the F1 long bristle females with their brothers gives only long bristle F2 progeny. A cross of short bristle females with their brothers gave 1/3 long bristle females, 1/3 short bristle females, and 1/3 long bristle males. A) Explain what is going...

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...

In the fruit fly Drosophila melanogaster, wild type eye color is a brick red color and...

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...

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...

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

A researcher studying the effects of a certain pesticide on fruit flies (Drosophila melanogaster) in the lab found that it binds to the spliceosomes (the enzymes that cut/splice the initial RNA transcripts) and caused the spliceosome to be non-functional. What effect would this have on the gene expression of the fruit flies?
