A geneticist interested in studying variations and patterns of inheritance in living beings prefers to choose organisms for experiments with shorter life cycle. Provide a reason.
A pea plant which is homozygous for green pods which are inflated [GGII] is crossed with a homozygous plant for yellow pods which are constricted [ggii]. Answer the following questions;
a) Give the phenotype and genotype of the F1 generation.
Which type of pollination has occurred to produce F1 generation?
b) Write the phenotypic ratio of the F2 generation
c) Write the possible combinations of the gametes that can be obtained if two F1 hybrid plants are crossed.

5) What is the scientific name of the plant which Mendel used for his experiments on inheritance?
Define the following:
Recessive
RR (Red) Antirrhinum is crossed with white (rr) one. Offspring (Rr) are pink. This is an example of ______.
______ pairs of contrasting characters in pea plants were studied by Mendel in his experiments.
The material used for conducting experiments on genetic traits by Mendel was ______.
Read the following and answer from given below:
According to Mendel, one gene controls the expression of one character only. The ability of a gene to have multiple phenotypic effects because it influences a number of characters are an exception. The gene has multiple phenotypic effects because its ability to control two or more characters can be seen in cotton. In cotton, a gene for the lint also influences the height of the plant, size of the ball, number of ovules, and viability of seeds.
Which of the following statements is not correct regarding genes with multiple phenotypic effects?
Give the basic features of the mechanism of inheritance.
