8. Use the rule of multiplication to find out the probability of a pea plant to be green and wrinkled if both parents are yellow and round (heterozygous) YyRr x YyRr = yyrr

0.5 • 0.5 • 0.5 • 0.5 = 0.0625 or 6.25%

There’s a 0.5 chance of getting a y allele from parent 1, 0.5 chance of getting an r allele from parent 1, 0.5 chance of getting a y allele from parent 2, and 0.5 chance of getting an r allele from parent 2.
