Is Star eyes recessive or dominant?

Star (S) is a spontaneous dominant mutant at 1.3 in the second chromosome (BRIDGES and MORGAN I ~ I ~ ; , S T E R N and BRIDGES 1926). S/+ flies have slightly reduced eyes with irregularly shaped facets and disarranged facet hairs. The S homozygote is lethal.

What causes Bar eye in Drosophila?

One phenotype that has been analyzed in Drosophila with respect to duplications is bar eye. The eye of the fly is normally an elongated oval shape whereas the bar eye phenotype is much thinner. When the chromosomes of males with bar eye are analyzed, a duplication in region 16A of the chromosome is detected.

How Drosophila is a good model for diseases?

melanogaster models of human diseases provide several unique features such as powerful genetics, highly conserved disease pathways, and very low comparative costs. The fly can effectively be used for low- to high-throughput drug screens as well as in target discovery.

What is Drosophila used for?

Drosophila has been used productively as a model organism for over a century to study a diverse range of biological processes including genetics and inheritance, embryonic development, learning, behavior, and aging.

What is white eye mutation in Drosophila?

white, abbreviated w, was the first sex-linked mutation discovered, found in the fruit fly Drosophila melanogaster. In 1910 Thomas Hunt Morgan and Lilian Vaughan Morgan collected a single male white-eyed mutant from a population of Drosophila melanogaster fruit flies, which usually have dark brick red compound eyes.

Why Drosophila is a good model?

Another advantage of Drosophila is that they are very small and thus, very easy to maintain. Due to their small size and minimal requirements, many Drosophila can be raised and tested within a small laboratory which does not have access time, space or funding. Genetic factors also make this fly an ideal model organism.

What is the pattern of inheritance of eye color in Drosophila?

The eye color gene is located on the X chromosome (one of the sex determining chromosomes of Drosophila). White eye color is recessive. When a red eyed male mates with white eyed females, their daughters will have red eyes, but their sons will have white eyes.

Can female Drosophila have white eyes?

All of the females and all of the males will have red eyes. All of the females will have white eyes; half of the males will have red eyes, and half of the males will have white eyes.

What does W mean in Drosophila?

showSearch for. white, abbreviated w, was the first sex-linked mutation discovered, found in the fruit fly Drosophila melanogaster.
