sex-linked traits: traits controlled by genes located on thr sex
... SEX-LINKED TRAITS: TRAITS CONTROLLED BY GENES LOCATED ON THR SEX CHROMOSOMES. X = FEMALE SEX CHROMOSOME Y = MALE SEX CHROMOSOME (SMALLER THAN X AND DOES NOT CONTAIN AS MANY GENES) Objectives: 1) Define through example sex-linked traits and polygenic inheritance. 2) Identify other factors that might ...
