Please help me with this question:

D). 100% of the females with red eyes, 100% of the males with white eyes.

Explanation: If XR represents the allele for red eyes and Xr represents the allele for white eye, and if the allele for red eyes is dominant and the allele for white eyes is recessive. Then the cross between the two will produce four offsprings, two females and two males. The females will be heterozygous for the trait having one dominant allele and one recessive allele XRXr while the males will have one allele for white eye and a Y chromosome XrY. Since XR is dominant, the females with genotype of XRXr will manifest red eye phenotype while the males with genotype of XrY will manifest phenotypically as white eyed because they have only one X chromosome.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".

the answer is sex-linked recessive.
