What is difference between male and female Drosophila?

The most simple characteristic to use to differentiate the two is to look at the genitalia of the flies. Males have dark, rounded genitalia at the tip of their abdomen, whereas females have light, pointed genitalia. Male Drosophila are generally smaller than their female counterparts, and have a darker abdomen.

What are the characteristics of Drosophila?

It has a rounded head with large, red, compound eyes; three smaller simple eyes, and short antennae. Its mouth has developed for sopping up liquids (Patterson and Stone 1952). The female is slightly larger than the male (Patterson, et al 1943).

Are female Drosophila bigger than males?

Drosophila females are larger than males. In the presence of two sets of X-chromosome signal elements (XSEs), Sex-lethal (Sxl) is activated in female (XX) but not male (XY) animals. Sxl activates transformer (tra), a gene that encodes a splicing factor essential for female-specific development.

How do you know if a Drosophila is virgin?

Note that virgin females are much larger than older females and do not have the dark coloration of mature females. In addition, in the early hours after eclosure, there will be visible a dark greenish spot (the meconium, the remains of their last meal before pupating) on the underside of the abdomen.

What is the family of fruit fly?

Fruit fly, any two-winged insect of either the family Trypetidae or the family Drosophilidae (order Diptera) whose larvae feed on fruit or other vegetative matter. Insects of the family Trypetidae are often referred to as large fruit flies, and those of the Drosophilidae as small fruit flies or vinegar flies.

How many eggs do Drosophila lay?

The fruit fly’s life cycle begins when the female lays her eggs on a piece of fermenting fruit or other decaying, sweet organic material. She can lay up to 500 eggs, making it difficult to control the population.

How are male and female genitalia in Drosophila different?

Male and female genitalia in Drosophila are derived from separate cell populations. In male (XY) flies, the female primordium is repressed, and the male primordium differentiates into the adult genital structures. In female (XX) flies, the male primordium is repressed, and the female primordium differentiates.

What’s the difference between a male and a female melanogaster?

The female Drosophila melanogaster or the female fruit fly is also yellow-brown in colour. However, their pattern on stripes varies as more number of stripes are seen in female organisms. They are placed far apart and not thick in nature. These stripes are black in colour and light in female Drosophila melanogaster.

What kind of eyes does a Drosophila melanogaster have?

What’s the difference between a male and female fruit fly?

The main difference between male and female fruit flies is that male fruit flies are comparatively small in size whereas female fruit flies are around 25% larger than their male counterparts. Furthermore, the abdomen of the male fruit fly is rounded at the bottom while the abdomen of the female fruit fly is pointed at the bottom.
