Question

What was the first generation of offspring in Mendel's experiment called?

Answer 1

F1 generation.

Explanation:

For one of his early experiments, Mendel established two pure-breeding lines of peas that produced yellow seeds and green seeds.

He crossed these two varieties by transferring pollen from a plant of yellow variety to one of the green variety and from the green to the yellow variety.

In either case, the results were the same--all the seeds produced by these plants, the F1 generation, were the same yellow color.

Mendel described yellow as being dominant, to green, which was termed recessive.
