Question

What characteristic are exhibited by y linked traits?

Answer 1

Y-linked inheritance. Y-linked traits never occur in females, and occur in all male descendants of an affected male. The concepts of dominant andrecessive do not apply to Y-linked traits, as only one allele (on the Y) is ever present in any one (male) individual.

Answer 2

Y linkage can be difficult to detect. This is partly because the Y chromosome is small and contains fewer genes than the autosomal chromosomes or the X chromosome. It is estimated to contain about 200 genes. Earlier, the human Y chromosome was thought to have little importance;[2]. Although the Y-chromosome is sex-determining in humans and some other species, not all genes that play a role in sex determination are Y-linked. The Y-chromosome, generally does not undergo genetic recombination and only small regions called pseudoautosomal regions exhibit recombination. The majority of the Y-chromosome genes that do not recombine are located in the "non-recombining region"
