In pea plants, the allele for yellow seeds (y) is dominant over the allele for green seeds (y). describe the genotypes and phenotypes of pea plants that are homozygous dominant, homozygous recessive, and heterozygous for this trait.

Homozygous Dominant: YY

- A pure yellow pea pod

Homozygous Recessive: yy

- A pure green pea pod

Heterozygous: Yy

A yellow pea pod.

Recessive traits are only displayed when the genotype contains two recessive alleles.

what are the choices?

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
