The material used for conducting experiments on genetic traits by Mendel was ______.
Which of the following characters can be acquired but not inherited?
Read the following and answer from given below:
Prashant wanted to find the genotype of a pea plant bearing purple coloured flowers in his kitchen garden. For this, he crossed purple-flowered plants with white-flowered plants. As a result, all plants which were produced had purple flowers only. Upon selfing these plants, 75 purple flower plants and 25 white flowers plants were produced. Now, he can determine the genotype of a purple-flowered plant by crossing it with a white-flowered plant.
The character i.e., the purple colour of the flowers that appeared in the first filial generation is called ______
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.
Genes with multiple phenotypic effects are known as ______
A gene showing dominance has:
If a cross between two individuals produces offspring with 50% dominant character (A) and 50% recessive character (a) then the Genotypes of parents are:
