3PRACTICE PROBLEM
A pea plant experiment is conducted to study the genetic linkage of two genes: seed color (Y, yellow or y, green) and seed shape (R, round or r, wrinkled). A dihybrid heterozygous (YyRr) plant is crossed with another dihybrid heterozygous (YyRr) plant. They produce the following progeny:
Yellow and round: 120
Yellow and wrinkled: 43
Green and round: 39
Green and wrinkled: 8
What is the chi-square value?
