What defines our gender? |
Our 23 chromosome set.
XY = male (has one smaller Chromosome) XX = female |
|
|
|
How can you tell if a sex-linked trait has passed onto the offspring? |
The X chromosome. Disorders are recessive traits that can be carried on through the X Chromosome.
XX = normal female XY = normal male Xx = Carrier of a disorder xx = effected xy/xY = effected Females pose a threat. |

|
By using this Punnett Square, determine who has a disorder.
X x ________ X|XX Xx Y|XY xY |
xY. ¼, 25% is infected. The male is infected |
|
|
|
What does a female carrier look like crossed with a normal male? No Punnett required. |
Xx × XY |

A family with 1 and 2 |
Squares are usually male and Circles are usually female. Shapes that are shaded in are those infected. |

|
What is a Human Pedigree? |
A chart that shows the phenotype of a gene through generations. It helps determine whether a trait is dominant or recessive. |

XYY XYYY |
Formula example: XX = Female |
