Question

anytime i cross a heterozygous individual with a heterozygous individual, the box i use is...
○ 1×1
○ 2×1
○ 2×2
○ 4×4

Explanation:

In genetics, a Punnett square is used to predict offspring genotypes. When crossing two heterozygous individuals (e.g., Aa × Aa), each parent can produce two types of gametes. A 2×2 Punnett square has 2 rows (for one parent's gametes) and 2 columns (for the other parent's gametes), allowing all possible combinations (2×2 = 4) to be shown. A 1×1 or 2×1 square is insufficient, and 4×4 is for more complex crosses (e.g., dihybrid with two traits, each with two alleles, but here it's a monohybrid cross with two heterozygotes, so 2×2 is correct).

Answer:

C. 2×2 (assuming the options are labeled as A. 1×1, B. 2×1, C. 2×2, D. 4×4; if labels differ, adjust to match, but the correct square is 2×2)
