Heterozygous individuals that can pass on recessive, abnormal conditions are referred to as: Dominant alleles are seen as an uppercase of a letter; A trait appears in both men and women with equal frequency, and offspring can inherit the trait from the mother or the father. In genealogy, the male lineage is often traced using the y chromosome because it is only passed down from the father. All affected individuals have at least one affected parent.
This happens because in females the white eyed recessive gene from the mother is covered by the red eye dominant gene. All affected individuals have at least one affected parent. The y chromosome is a puny bit of dna that has only a few genes. Can a recessive trait be on the y chromosome recessive traits may skip generations and will affect both genders equally.

All affected individuals have at least one affected parent. White eyed mother (xrxr) + red eyed male (xry) =. This happens because in females the white eyed recessive gene from the mother is covered by the red eye dominant gene.
A recessive trait is expressed only in homozygous state in diploids as its effect is masked by presence of dominant allele in the heterozygous condition.
Dominant alleles are seen as an uppercase of a letter; A recessive trait is expressed only in homozygous state in diploids as its effect is masked by presence of dominant allele in the heterozygous condition. (use x—the dominant allele of the trait on the x chromosome, x'—the recessive allele of the trait of the x chromosome and y—the y chromosome in all males) if the numbers of affected males and females are nearly the same, then that is an indication that you are dealing with an autosomal trait.
