A fruit fly geneticist discovered a genetic mutation that resulted in pupae and young flies with dark pigment granules in the nuclei and cytoplasm of their fat cells. After studying the inheritance of the mutation, the geneti- cist named the gene Frd (for Freckled). What does this name tell you about the inheritance of this gene? In...

A fruit fly is found that has three sex chromosomes (XXY) and three of each autosome. The sex of this fruit fly is _ because ___. A. female; it has a 1:1 ratio of sex chromosomes to autosomes B. male; it has a Y chromosome C. female; it has 2 X chromosomes D. intersex; it has an X:A ratio between 0.5 and 1 E. impossible to determine; sex is influenced by environment in insects

Most penguin species are not sexually dimorphic, which means they lack obvious outward body characteristics which indicate sex. Observation of behavior or a blood test can determine Penguin sex. A penguin researcher is interested in estimating the proportion of females in a large penguin population. She takes a random sample of n = 20 penguins and determines the sex of each one using a blood test. She finds 12 males and 8 females. Let π be the proportion of females...

A pure-breeding fruit fly with curled wings mates with a pure-breeding fruit fly with normal (straight) wings. The F1 mate with each other to produce an F2 generation that consists of 160 flies with curled wings and 80 with straight wings. What can you infer from this observation? A. Wing shape is controlled by two codominant alleles. B. All of the hybrid F1 flies had straight wings C. Two interacting genes determine wing shape. D. The dominant curled wing allele...

The dominant mutotion Plum in the fruit fly causes brownish-purple eyes. Is it possible to determine by genelic experiments (e.complementation) whether Plum is an elleie of the brown or purplo genes? Why?

1 point) The common fruit fly Drosophila melanogaster is the most studied organism in genetic research because it is small, easy to grow, and reproduces rapidly. The length of the thorax (where the wings and legs attach) in a population of male fruit fies is approximately Normal with mean 0.800 millimeters (mm) and standard deviation 0.078 mm. Note: Use Table A to find the proportion below (a) What proportion of flies have thorax length 0.83 mm or longer? (b) What...

A geneticist looks through a microscope to determine the phenotype of a fruit fly. The microscope is set to an overall magnification of 400x with an objective lens that has a focal length of 0.40 cm. The distance between the eyepiece and objective lenses is 14 cm. 1)Find the focal length of the eyepiece lens assuming a near point of 25 cm (the closest an object can be and still be seen in focus). Do not neglect any values in...

Sperm tails in the fruit fly Drosophila bifurca can reach up to 6cm long, which is over 20 times the length of the organism itself. Because the tails are so long, they aren't able to provide the swimming force that other sperm tails are used for. Please provide a hypothesis as to why the fruit fly sperm has evolved to be so long.
