the sex chromosomes carry genes that affect traits other than the individual's sex. these are called
sex-linked genes
-
most sex-linked genes have alleles on the x chromosome and are called
x-linked genes
-
x-linked genes are most often dominant or recessive
recessive
-
______ ______ is an x-linked, recessive trait
