Sex Determination¶
The sex of a living thing can be established through the special alleles that determine the sex. For example in humans, the X and Y chromosomes are used for determining sex, two X chromosomes - you're female, one of each - you're male.
Genetic Cross¶
You can use a genetic cross, to show the probabilities of the sex of a human baby.
| X | Y | |
|---|---|---|
| X | XX | XY |
| X | XX | XY |
Using the genetic cross, you can establish that there is equal chance, the baby being male or female.
