What is the percent chance that an offspring will have yellow pods?

To determine the chance that an offspring will have yellow pods, it is essential to understand the underlying genetics, particularly Mendelian inheritance patterns. In this scenario, the phenotype of pod color can be attributed to specific alleles where the yellow pod color is often associated with a dominant trait.

Assuming yellow pods (Y) are dominant over green pods (y), we can analyze the genetic combinations produced by two heterozygous parents (Yy). The possible gamete combinations from each parent are Y and y. When these are crossed, the resulting offspring can inherit the following genotypes:

1. YY (homozygous dominant) – yellow pods

2. Yy (heterozygous) – yellow pods

3. yy (homozygous recessive) – green pods

Using a Punnett square visualizes this cross, showing these combinations:

• YY

• Yy

• Yy

• yy

From this analysis:

• 3 out of the 4 possible genotypes (YY and Yy) express the yellow pod phenotype.

• This gives a ratio of 3 yellow pod plants to 1 green pod plant, translating to a probability of 75% for yellow pods.
