## **7.L.4A.4 Use mathematical and computational thinking to predict the probability of phenotypes and genotypes based on patterns of inheritance. **

Patterns of genetic inheritance obey the laws of probability. In a monohybrid cross, where the alleles present in both parents are known, each genotype* shown in a Punnett Square is equally likely to occur. Since there are four boxes in the square, every offspring produced has a one in four, or 25%, chance of having one of the genotypes shown. Click on the link below to practice.

Challenge: Use the following Gizmos to discover how certain traits are passed on through inheritance.
