Final answer:
a. A monohybrid cross involves the study of one genetic trait, while a dihybrid cross involves the study of two genetic traits. The Punnett square is a tool used to predict the outcomes of genetic crosses in both cases.
Step-by-step explanation:
Punnett Squares for Monohybrid and Dihybrid Crosses
a. A monohybrid cross involves the study of one genetic trait, while a dihybrid cross involves the study of two genetic traits. The Punnett square, a tool used to predict the possible outcomes of a genetic cross, is used in both types of crosses.
The main difference between a Punnett square for a monohybrid cross and a dihybrid cross is the number of possible combinations of alleles. In a monohybrid cross, there are two possible combinations, while in a dihybrid cross, there are four possible combinations.
