Is Apterous wings dominant or recessive?
recessive trait
In traditional or Mendelian genetics, the gene for apterous flies is a recessive trait. This means that a fruit fly must get the gene for aptery from both parents. If the fly has a single copy of the gene for normal wings, it will mask the presence of the gene for aptery and the fly will develop normal wings.
Is vestigial wings autosomal recessive?
Vestigial wing is a recessive autosomal mutation in the fruit fly Drosophila melanogaster. Wild-type flies have red eyes, but another mutation, an X-linked recessive mutation causes white eyes. You cross a parental generation of males with vestigial wings with females that have white eyes.
What chromosome is Apterous wings on?
H. MORGAN. This mutant,’which occurred spontaneously, was shown by C. W. METZ (1914) to be recessive and located on the second chromosome near the black (6) locus.
Is Ebony autosomal recessive?
Ebony is a recessive trait; the F1 progeny of ebony and brown are brown.
Is sepia autosomal recessive?
Sepia eyes (se, 3; 26.0) are an autosomal recessive trait on Chromosome 3 that produces a dark brown eye color.
Is VG recessive or dominant?
Having Trouble?
| Mutation | Inheritance pattern | Genotypes possible for wild-type phenotypes |
|---|---|---|
| vestigial wings | recessive | +/+; +/vg |
| curly wings | dominant | +/+ |
| eyeless | recessive | +/+; +/ey |
| ebony body color | recessive | +/+; +/e |
What does Apterous mean in biology?
apterous (not comparable) (zoology) Destitute of wings; wingless. quotations ▼ (biology) Destitute of winglike membranous expansions, as a stem or petiole.
Is Ebony dominant or recessive?
Ebony is a recessive trait; the F1 progeny of ebony and brown are brown. Ebony is not a sex-linked trait because body color is not dependent on sex.
Are sepia eyes autosomal recessive?
Sepia colored eyes are a result from a recessive gene, and only result when two sepia-eyed flies mate or when two heterozygous flies mate.
Is sepia dominant or recessive?
recessive gene
Brown and sepia eyes are a result of a recessive gene and only occur when two sepia-eyed flies mate.
Are sepia eyes and vestigial wings linked?
The results were clear and allowed the null hypothesis to be correct. The white eyed gene in the fruit flies is sex linked. Sepia eyes and vestigial wings are not sex linked and are examples of independent assortment.
Are dumpy wings recessive?
dp, dumpy: second chromosome recessive, wide wing with notch at the end. vg, vestigial: second chromosome recessive, tiny crumpled wings. CyO, Curly: second chromosome dominant, curly wings.
Is Ebony body dominant or recessive?
What chromosome is the dumpy gene on?
X chromosome
(b) The domain composition of the 441 amino acid Mini-dumpy, which we located on the X chromosome at 19A by in situ hybridisation to salivary gland polytene chromosomes.
What gene causes fruit flies to have only one pair of wings?
What gene causes them to have only one pair of wings? they have turned off the formation of a second pair of wings in segment #3 due to the Ubx gene.
Which chromosome is the ebony gene on?
the third chromosome
As a candidate gene on the third chromosome, ebony was selected for population genetic analysis and association testing.
Are vestigial wings dominant in Drosophila?
Flies with vestigial wings cannot fly: they have a defect in their “vestigial gene,” on the second chromosome. These flies have a recessive mutation. Of the pair of vestigial genes carried by each fly (one from each parent), both have to be altered to produce the abnormal wing shape.
