Questions & Step-by-Step Solutions

What is the role of a Punnett square? (2023)
  • Step 1: Understand that a Punnett square is a tool used in genetics.
  • Step 2: Know that it helps predict the traits of offspring from two parent organisms.
  • Step 3: Identify the genotypes (genetic makeup) of the parents involved in the cross.
  • Step 4: Draw a grid (the Punnett square) to organize the possible combinations of alleles from each parent.
  • Step 5: Fill in the squares with the possible genotypes of the offspring based on the parents' alleles.
  • Step 6: Analyze the results to see the likelihood of different genotypes in the offspring.
