Mendel combined a purebred yellow seeded plant with a purebred green seeded plant, and he got only yellow seeds.

What peas?

Carrots or peas?

So we could have all these possible combinations round yellow peas, round green peas, wrinkled yellow peas, wrinkled green peas.

Let's look at Mendel's peas, for example.

He had a heart as big as a house and a brain the size of a pea.

And in this second generation, he got both yellow and green seeds, which meant the green trait had been hidden by the dominant yellow.

Then he let the new yellow seeded hybrid plants self fertilize.

Found us a boarding house with builtin blackeyed peas and grits.

Bissel Gardens is cranking out food in epic proportions, moving kids into an economy they never imagined.

Marry her, and you can all live here as happy as three peas in a pod.

Depending on which type of allele Mendel found in each seed, we can have what we call a homozygous pea, where both alleles are identical, and what we call a heterozygous pea, when the two alleles are different.

The uppercase Y always overpowers his lowercase friend, so the only time you get green babies is if you have lowercase Y's.

In Mendel's first generation, the yellow homozygous pea mom will give each pea kid a yellow dominant allele, and the green homozygous pea dad will give a green recessive allele.
