a scientist crosses two pea plants with yellow - colored seeds and grows the offspring. the scientist records the colors of the seeds produced by the resulting offspring in a table.

seed color	percent of offspring
green	25

how can parent plants with yellow seeds produce offspring plants with green seeds?
the gene for green seeds is recessive to the gene for yellow seeds, and
the parents had both genes
some plants only get genes from one parent

Explanation:

In genetics, when a trait like green - seed color appears in offspring while parents have a dominant trait (yellow - seed color), it's because the green - seed gene is recessive. Offspring inherit genes from both parents. If both parents carry the recessive green - seed gene along with the dominant yellow - seed gene, through random inheritance, some offspring can receive two recessive genes and thus show the green - seed trait.

Answer:

The gene for green seeds is recessive to the gene for yellow seeds, and the parents had both genes.
