he Punnett square shows the cross for a particular trait between a homozygous dominant parent and a heterozygous parent. What is
the probability the offspring will be heterozygous for this trait? 25% 50% 75% 100%
1 answer:
Answer:
50%
Explanation:
Let's make a Punnett square to represent this, with X representing our dominant allele and x our recessive.
One homozygous dominant parent = XX
One heterozygous parent = Xx
X X
X XX XX
x Xx Xx
So two out of our four outcomes are heterozygous for the trait. That means the answer is <u>B. 50%.</u>
