I need help with the image (phenotypes and genotypes).
Flauer [41]

Answer:

See the answer below

Explanation:

1. <u>Only one phenotype</u> is present in the F1 generation offspring. Since tallness was dominant over shortness, all the offspring in the F1 generation appeared tall.

2. <u>Two phenotypes </u>are present in the F2 generation - 9 tall and 3 short. The short trait reappeared at the F2 generation.

3. The genotype of the F1 offspring would be heterozygous. Assuming the purebred tall is AA and the purebred short is aa:

     AA   x   aa

  Aa   Aa   Aa   Aa

All the F1 offspring will appear tall and their genotypes would be heterozygous.

4. Assuming that the allele for height is denoted with A (a), <u>the genotype of the purebred tall plant would be AA. </u>

5. In a similia vein, <u>the genotype of the purebred short plant would be aa. </u>
