PPT-Sex-Linked Traits

Humans have 46 chromosomes in every cell 2 of these chromosomes make us male or female Female XX Male XY The Sex Chromosomes Has information for male traits Few other genes The Y chromosome. Linked List Linked List Linked List

The Y chromosome is shorter than X; therefore, some genes on the X chromosome may be missing from Y. Sex-linked disease is less likely to affect females because they have 2 X chromosomes. Which gender (male or female) is most likely to have sex-linked traits? . How many X chromosomes do males have? . How many X chromosomes do females have? . Why does a single X chromosome that carries the allele for red-green colorblindness cause males to be color blind but . KEY CONCEPT .
