Sex Linkage

Sex Linkage. X-linked Traits. Recall that the 23 rd chromosome in humans dictates the gender of the individual The Y chromosome is much smaller, and carries much less genetic info. X chromosome. Y chromosome. Colourblindness. Hemophilia. 70-200 genes. 900-1600 genes.

Probability and Punnett Squares

Probability and Punnett Squares. Probability is a way of expressing knowledge or belief that an event will occur or has occurred. The likely hood of cross will produce a particular type of offspring. Probability. Percentage- way of expressing a number as a fraction of 100
