Q: What is the main purpose of a Punnett square? (2020)
Solution:
A Punnett square is used to predict the genetic variation and possible genotypes of offspring from a genetic cross.
Steps: 6
Show Steps
Step 1: Understand that a Punnett square is a tool used in genetics.
Step 2: Know that it helps to visualize how genes from parents combine.
Step 3: Identify the parents' genotypes (the genetic makeup).
Step 4: Draw a grid (the Punnett square) to organize the possible combinations of genes.
Step 5: Fill in the grid with the possible gene combinations from each parent.
Step 6: Analyze the grid to see the possible genotypes of the offspring.
