______

1. for which trait(s) was your snowman heterozygous? list only the genotypes below.

______

1. complete a punnett square of two parents both heterozygous for the number of snowballs that make up your snowman. state the phenotypes as a percentage.

Explanation:

Step1: Analyze Question 2

In human reproduction, a baby (embryo) has 46 chromosomes. Half (23) come from the mother (via the egg) and half (23) from the father (via the sperm). To find the percentage, use the formula: $\frac{\text{Number from parent}}{\text{Total in baby}} \times 100$. For the mother: $\frac{23}{46} \times 100 = 50\%$. Same for the father.

Step2: Confirm Calculation

Total chromosomes in baby: 46. From mother: 23, from father: 23. $23/46 = 0.5$, $0.5 \times 100 = 50\%$ for both.

Answer:

Percentage from mother: 50%
Percentage from father: 50%
