What is the expected outcome when a homozygous recessive plant (ss) is crossed with a heterozygous plant (Ss) regarding seed shape?

• A. All spherical
• B. All dented
• C. 50% spherical, 50% dented
• D. 75% spherical, 25% dented

Answer: (C)

The expected outcome of crossing a homozygous recessive plant (ss) with a heterozygous plant (Ss) can be understood through a basic Punnett square analysis. In this scenario, the homozygous recessive plant will always contribute a recessive allele (s) to the offspring, while the heterozygous plant can contribute either a dominant allele (S) or a recessive allele (s). Setting up the cross, the possible gametes from each parent are as follows: the homozygous recessive (ss) can only give "s," and the heterozygous (Ss) can give either "S" or "s." Thus, the resulting combinations from the cross are: 1. From "S" (from the heterozygous parent) and "s" (from the homozygous recessive parent) resulting in "Ss" (heterozygous). 2. From "s" (from the heterozygous parent) and "s" (from the homozygous recessive parent) resulting in "ss" (homozygous recessive). Thus, the genotypic outcomes will be: - 50% Ss (heterozygous) with the

Setting up the cross, the possible gametes from each parent are as follows: the homozygous recessive (ss) can only give "s," and the heterozygous (Ss) can give either "S" or "s." Thus, the resulting combinations from the cross are:

1. From "S" (from the heterozygous parent) and "s" (from the homozygous recessive parent) resulting in "Ss" (heterozygous).

2. From "s" (from the heterozygous parent) and "s" (from the homozygous recessive parent) resulting in "ss" (homozygous recessive).

Thus, the genotypic outcomes will be:

• 50% Ss (heterozygous) with the
