Which describe the fruit fly genotype and phenotype?

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 phenotype of a fruit fly?

In fruit flies, two possible body color phenotypes are brown and black. Two alleles for body color are brown and black.

What is the genotype of the female fruit fly quizlet?

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. A white-eyed female fruit fly is crossed with a red-eyed male.

What is the genotype of the 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.

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 fly?

Possible female genotypes

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 meant by genotype?

In a broad sense, the term “genotype” refers to the genetic makeup of an organism; in other words, it describes an organism’s complete set of genes. Humans are diploid organisms, which means that they have two alleles at each genetic position, or locus, with one allele inherited from each parent. …

What is phenotype example?

Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.

What is an example of heterozygous genotype?

There are different versions of genes. … If the two versions are different, you have a heterozygous genotype for that gene. For example, being heterozygous for hair color could mean you have one allele for red hair and one allele for brown hair. The relationship between the two alleles affects which traits are expressed.
