Best answer: What is the genotype of the female fruit fly quizlet?

What is the genotype of a male fruit fly quizlet?

The sex of the fruit fly Drosophila melanogaster is determined as follows: XX chromosomes give a female and XY give a male.

What is the genotype of a female quizlet?

– determine an organisms sex. – genes on sex chromosomes are called sex linked genes. – females have XX genotype. – since males have 1 copy of X, all of their sex linked genes are expressed.

What is the genotype of a male fruit fly?

The sex of the fruit fly Drosophila melanogaster is determined as follows: XX chromosomes give a female and XY give a male. The gene for bar eyes is recessive and located on the X chromosome. A male has a genotype RrTt.

Which describe the fruit fly genotype and phenotype?

Genotype and phenotype of fruit fly:

The genotype refers to the entire hereditary information of an organism whereas phenotype refers to the physical character of an individual. The fruit fly is a heterozygous for eye color as it has both black eyes and red eyes.

What is the genotype of a fruit fly?

In fruit flies, the dominant V allele produces long wings, whereas the recessive v allele produces vestigial wings. Thus, flies with the genotype VV or Vv will have long wings, and flies with the genotype vv will have vestigial wings.

What is the genotype of a female who is heterozygous for eye color quizlet?

Female must be heterozygous because she can transmit either the red eye or white eye allele to her sons and daughters. Therefore the female must be a heterozygous, Xw+ Xw. What is the genotype of a red-eyed, yellow-bodied female fruit fly who is homozygous for the eye color allele?

What is the genotype of the female fruit fly?

Since the female fly has a yellow body, and the tan body color is the dominant allele, she will be homozygous recessive for yellow body color. Therefore, the female fly will be homozygous for both traits. The genotype is Xw+y Xw+y.

What is the genotype of the female P generation fly?

a) The genotypes of the flies in the P generation are: BBnn female and bbNN male.

How do you determine genotypes?

A Punnett square is one of the simplest ways to determine genotype. The square is actually a mini-chart used to determine the potential genotype for an offspring with respect to particular trait.

What is the genotype of a white eyed male fruit fly?

Like humans, Drosophila males have an XY chromosome pair, and females are XX. In flies, the wild-type eye color is red (XW) and it is dominant to white eye color (Xw) (Figure 1). Drosophila males lack a second allele copy on the Y chromosome; that is, their genotype can only be XWY or XwY.

Are fruit flies hermaphrodites?

An unshared love. Pletcher and colleagues played a most cruel prank on male fruit flies. … Now, for this particular nematode species, sex may not be the word to describe them since 99% of all specimens are hermaphrodites (lay eggs and produce sperm at the same time), while only 1% are males.
