Genetic Crosses and Sex Determination

Explain the fundamental genetic terms: gamete, homozygous, heterozygous, dominant, and recessive.
Describe the principles of single gene inheritance, identifying the function of dominant and recessive alleles.
Use genetic diagrams to illustrate and predict the results of single gene crosses.
Apply direct proportions and simple ratios when analyzing genetic crosses.
Apply concepts of probability to successfully predict the outcomes of genetic crosses.
Understand that most phenotypic features result from the interaction of multiple genes rather than single gene inheritance (knowledge of epistasis is not required).
Describe the biological mechanism of sex determination in humans.
