The Punnett square is used to:
AMeasure gene linkage distances
BShow DNA sequence
CIdentify chromosome number in a cell
DGraphically calculate the probability of all possible genotype combinations in a genetic cross
Answer & Solution
Correct answer: D. Graphically calculate the probability of all possible genotype combinations in a genetic cross
**Punnett square** (developed by R.C. Punnett) is a tabular graphical method to predict all possible genotype combinations of offspring in a cross. Gametes go on the two sides; combinations fill the squares.
