Y-linked traits How does it work? This is a rare type of inheritance, where the gene of interest is located on the Y-chromosome. Because, at most, one copy of the Y chromosome is inherited, dominant and recessive don’t really apply here. How can you identify a Y-linked dominant trait?

The dominant allele is capitalized and the recessive allele is lower case. The letter used for the gene (seed color in this case) is usually related to the dominant trait (yellow allele, in this case, or “Y“). Mendel’s parental pea plants always bred true because both produced gametes carried the same allele.

Male and female both are affected, but females are affected in excess and less severely. Affected males can transmit the mutant allele to female offspring but not to male offspring. Figure í ì.: X-linked dominant inheritance where the father carries the faulty X-linked dominant gene and is affected. The faulty copy of the X-linked gene is represented by ‘D’, the working copy by ‘d’.

Dominant inheritance • The first “DBA gene” was cloned in 1997 and identified as RPS19, a gene that codes for an RP, located at chromosome 19q13.2.RPS19 mutations account for 20–25% of both sporadic and familial cases. Since that time an additional 11 genes have been identified (Table 8.2) comprising approximately 50–70% of DBA cases analyzed.

The inheritance and presentation of all three differ depending on the sex of both the parent and the child. This makes them characteristically different from autosomal dominance and recessiveness. Dominance is not inherent to an allele or its traits. It is a strictly relative effect between two alleles of a given gene of any function; one allele can be dominant over a second allele of the same gene, recessive to a third and co-dominant with a fourth.
