$If a plant with genotype A a B b is self-pollinated, what is the proportion of offspring that will have the same genotype as the parent?$

A. $1/2$
B. $1/8$
C. $1/4$
D. $3/16$

Show correct answer & step-by-step solution

Correct answer: C — $1/4$

Solution

$The cross is A a B b \times A a B b .$
$The probability of A a from A a \times A a is 1/2 .$
$The probability of B b from B b \times B b is 1/2 .$
$The combined probability is 1/2 \times 1/2 = 1/4 .$
$Hence the answer is (C).$
