Q: What is the purpose of a Punnett square?
Solution:
A Punnett square is used to predict the genotype ratios of offspring from a genetic cross.
Steps: 5
Show Steps
Step 1: Understand that a Punnett square is a tool used in genetics.
Step 2: Know that it helps predict what traits offspring might inherit from their parents.
Step 3: Realize that the square shows all possible combinations of alleles (gene variations) from each parent.
Step 4: Fill in the Punnett square with the alleles from each parent.
Step 5: Count the different combinations to find the ratios of possible genotypes in the offspring.
