Why do sex linked traits follow different patterns of inheritance than other traits ?

The right answer is A

The XY system of sexual determination is a genetic system of sex determination found in humans, most mammals, some species of insects (Diptera) and plants (Silene latifolia). He states that:

Females (women for humans) have two identical chromosomes (XX) while males (men for humans) have two distinct chromosomes (XY). X chromosome is longer than Y chromosome.

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.
