AReginald Punnett
BGregor Mendel
CWalter Sutton
DTheodor Boveri
Answer & Solution
Correct answer: A. Reginald Punnett
1. The grid that lists parental gametes along the top and side is the Punnett square.
2. It was devised by the British geneticist Reginald Punnett.
3. Mendel worked out the ratios themselves without using such a grid.
4. Sutton and Boveri are linked with the Chromosomal Theory of Inheritance instead.
