Heredity for 200

Based on the assumption that a Drosophila has the normal number of autosomes, what would be the sex of a Drosophila having XXY sex chromosomes?

What is female?Home

Mutations for 200

Flies that exhibit a “normal” phenotype, the one most common in their population, are said to have this type of phenotype.

What is a wild-type (gene,allele,phenotype)? Home

What is a caterpillar?

Home

Developmental Stages for 300

The average generation time of Drosophila is ___ to ___ days.

What is 9 to 10?

Home

Heredity for 300In Drosophila, eye color follows what

pattern or inheritance?

What is X-linked inheritance?

Home

Mutations for 300

Flies with this mutation produce no red pigment in their eye.

What is the White-eyed mutation?Home

Experiments for 300

Overanesthetizing a fruit fly can cause _____ or _____.

What is sterility or death?Home

General Characteristics for 300

What was the major discovery by Thomas Hunt Morgan using Drosophila?

What is X-linked inheritance?Home

Developmental Stages for 400Name 3 physical differences between

male and female Drosophila.

What is body size, wing size, genitalia color, presence/absence of sex combs on forelimbs, or abdomen shape (any 3).

Home

Heredity for 400

Why must virgin females be used in genetic crosses of Drosophila?

What is that females are capable of storing sperm from multiple partners and using it to fertilize eggs at a later time, which could skew results.

Home

Mutations for 400

There is a form of color mutation in flies that is responsible for building up tan-colored pigments in normal fruit flies. A mutation that produces a deficiency in the production of the mentioned gene will produce this abnormal color body.

What is Ebony(black) or what is the ebony gene?

Home

Experiments for 400

What is 8-12 hours?Home

Heredity for 500In Drosophila, sex is determined by the

ratio of _________ to _________.

What is the number of X chromosomes to the number of haploid sets of autosomes?

Home

Mutations for 500

Flies with this recessive mutation have a defect in the second chromosome in their “vestigial gene” that inhibits their ability to fly.

What is the short-winged mutation?Home

Experiments for 500Five reasons Drosophila make a good

model organism.

What is they produce many progeny, they are small in size, have a short generation time, are inexpensive, easy to culture/maintain in a lab, have large chromosomes, have many mutations available, a small genome (any 5)? Home
