What is the genotype of the red eyed male fly?

Homozygous dominant for the red encoding allele – genotype: XWXW; phenotype: red eyes. Heterozygous – genotype XWXw; phenotype: red eyes. Homozygous recessive with two white encoding alleles – genotype XwXw; phenotype white eyes.

What is the genotype of the red eye male?

Homozygous dominant for the red encoding allele – genotype: XWXW; phenotype: red eyes. Heterozygous – genotype XWXw; phenotype: red eyes. Homozygous recessive with two white encoding alleles – genotype XwXw; phenotype white eyes.

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 the genotype of the male?

The sex genotype for a human male is denoted as XY.

Why were all the white-eyed flies male?

Most of the white-eyed flies were male. … Morgan hypothesized that, in his breeding experiment, the first generation of flies contained males only with white eyes because the gene controlling eye color was on the X chromosome. Males displayed the white eye trait because the trait was present on their only X chromosome.

Why is the white-eyed characteristic more common in males?

Because the white-eye allele is recessive, a female will have white eyes only if she has the white-eye allele on both her X chromosomes. However, in males, a single copy of the white-eye allele on the lone X chromosome will lead to white eyes because no other allele is present.

What is the genotype for a purebred fly with white eyes?

Answer: According to the information in the question, the correct genotype for a pure breed fly with white eyes is EE. Explanation: Genotype for Pure breed organisms are made up of two similar alleles at the loci.

What does a 3 1 ratio mean in genetics?

The F2 generation always produced a 3:1 ratio where the dominant trait is present three times as often as the recessive trait. Mendel coined two terms to describe the relationship of the two phenotypes based on the F1 and F2 phenotypes.

What percent of males will have red eyes?

probability of getting red-eyed males? (You must include the probability of getting males AND red eyes). Step 5: One out of four (25% of) offspring will be both inale, and have red eyes.
