The Y chromosome from the father often does not carry an allele for a trait found on the X chromosome. Sex-Linked Alleles When considering X-linked traits, the allele on the X chromosome is sh ...

Introduction to Genetics (Genetics)

The first to speculate about how this process worked were Greek scholars around the 4th century bc, who promoted t ...
