are curly wings dominant in fruit flies?
479396
Notice the curled wings of these flies. They have a defect in their "curly gene," which is on the second chromosome. Having curled wings is a dominant mutation, which means that only one copy of the gene has to be altered to produce the defect. In fact, if both copies are mutated, the flies do not survive.

However, other scientists have reported that the interaction of two genes is responsible for this trait. This trait is reportedly due to a single gene; the presence of freckles is dominant, the absence of freckles is recessive1. Early geneticists reported that curly hair was dominant and straight hair was recessive.

The small, white “worms” are probably the larvae of the cherry fruit fly (Rhagoletis spp.). Cherry fruit flies lay eggs on developing cherry fruit in May. Damaged fruit appear shrunken and shriveled when ripe, and usually contain one off-white larva (maggot) that is slightly longer than one-quarter of an inch.

They both also have wings and antennae. Most species of gnats are very small, measuring one-quarter of an inch in length or less. On the other hand, flies are usually considerably larger. ... Like most species of flies, gnats are either dark-colored or black.

Fruit flies have a rounded silhouette like a smaller version of the common house fly. On the other hand, fungus gnats feature dangling legs and long bodies that make them appear similar to a small mosquito.

Flies can hover, move vertically, and even fly backwards, tantalizing you with your inability to catch the little buggers. Most flies flap their wings over 200Hz, or 200 cycles per second. A tiny fruit fly beats its wings once every 4 milliseconds — faster than neurons can fire.

An organism that is heterozygous for a trait has two different alleles for that trait. ... Flies that do not inherit the dominant allele have wrinkled wings. Flies that are heterozygous for the trait, having one dominant and one recessive allele, exhibit normal wings.

When flies see ultraviolet light, they are naturally lured in the direction of the source of UV rays. ... Indoor flies will be attracted to either the UV rays or the fly pheromones. Once attracted by UV rays, the insects must be captured, killed or contained.

While at a casual glance, phorid flies can be mistaken for fruit flies and drain flies, close inspection will reveal that they don't have the red eyes found in fruit flies, nor are they attracted to vinegar—one of the key identifying traits of fruit flies.

Red House Flies. Sometimes fruit flies are colloquially referred to as the red house fly due to their disproportionately large, red eyes. These tiny flies are attracted to decomposing fruit, as well as sugary liquids such as syrup, spilled soda and alcohol. These flies are irritating pests.

Fruit flies are attracted to rotting produce, which will ferment and produce alcohol which they will feed on. They will be attracted to the yeast in bread, so I would throw out the bread to be on the safe side.

Popular in the pet trade, the curly tail lizard is native to the Bahamas, and was introduced to Florida in the 1940's to combat sugar cane pests. Curly tails are sturdy, robust-looking lizards that sometimes grow to a length of 28 cms (11 inches). Their curled tail which is held up in the air easily identifies them.

House flies are gray with two distinct stripes on their face, large red eyes, and spongy mouthparts. ... Fruit flies are tiny beige flies with black rings, possess red or dark eyes, and are about a 1/8 inch plus or minus depending on the type. Their larvae are small, whitish-yellow, legless, and have a pointed head.

In vitro growth of curly hair follicles was slightly slower than that of caucasian follicles but, more importantly, the curvature was maintained in the hair shaft produced in vitro. ... Conclusions: Hair curliness is programmed from the bulb and is linked to asymmetry in differentiation programmes.

Since curly hair is a dominant gene, there is a good likelihood that one or two curly-haired parents will produce a curly-haired cutie. But genetics are tricky, and there's a chance that two parents with curls could carry the straight hair recessive gene, and pass that onto their offspring.

LEAVES CURLING The most common is the Cherry Blackfly. They attack the leaves causing them to curl upwards and inwards which protects the aphids from predators such as birds. ... Another sign of aphids is the presence of ants on the leaves or stems of the tree.
