Question

Pea plants were particularly well suited for use in Mendel's breeding experiments for all of the following reasons except that a. peas show easily observed variations in a number of characters, such as pea shape and flower color. b. it is possible to completely control matings between different pea plants. c. it is possible to obtain large numbers of progeny from any given cross. d. peas have an unusually long generation time

Answer 1

Answer:

. d. peas have an unusually long generation time

Explanation:

Gregor mendel is a scientist, he was bored 20th July,1822. He carried out an experiment using pea plant and he is reffer to as the father of genetist. Mendel used seven traits of the pea plant in his experiments this include flower color which is either purple or white, flower position which is either axil or terminal stem length which could be long or short, seed shape (round or wrinkled), seed color (yellow or green), pod shape (inflated or constricted) and pod color (yellow or green). He uses pea plant because of the following reason,

pea plant has many observable characteristics that could be used such as flower colors,seed shape.

Pea plant is an annual crop that matures early, so earliness to maturation makes Mendel select pea

Mating in pea plant can be controlled. Pea plant are self fertilizing crop but he decided to control the mating pattern by cross fertilize them and avoiding contamination from other pea plant.

The experiment with pea pant would produce enough seeds for subsequent generation.

This experiment made Mendel propound 2 laws, law of segregation of gene and law of Independent assortment of gene.
