What is the name of the scientist shown in the image who is considered the father of genetics?

Multiple choice question.

Gregor Mendel

2

The offspring of a pea plant with purple flowers and a pea plant with white flowers would be called ______.

hybrids

3

A cross between a true breeding tall plant and a true breeding short plant is an example of ______.

a hybridization experiment

4

Why was the common garden pea, Pisum sativum, that Mendel used in his genetic experiments an ideal specimen to study genetic crosses?

He used true breeding Pisum sativum plants with two distinct genotypes and phenotypes.

Reason:

The Pisum sativum plants were true breeding with two distinct genotypes and phenotypes. Crosses between tall plants produced tall plants. Crosses between short plants produced short plants. Crosses between tall and short plants produced a combination of tall and short plants which was the basis of Mendel's statistical analysis.
