In the green gram, the development of two flowers at the axial position is a recessive character, while the development of a single flower at the axial position is a dominant character. If the dominant character is represented by 'SS' and the recessive by 'ss' then answer the following question:

Find out the phenotype ratio in the second generation (F₂ generation) after crossing pure parental varieties.

Seema learned the chapter heredity and evolution in her school. She was so interested in the topic that she crossed pure breed pea plants having round-yellow seeds with wrinkled green seeds to see what happens. Seema found that only A-B type of seeds was produced in the F1 generation. Later when she crossed F1 generation pea plants having A-B type of seeds by self-pollination, then in addition to the original round yellow and wrinkled green seeds, two new varieties A-D and C-B types of seeds were also obtained.

What are the A-B type of seeds?

The chromosomes are located within each cell _____.

Each cell of human body contains _____ pairs of chromosomes.

The F₂ phenotypic ratio in a dihybrid cross is:

The mechanism of transmission of characters from the parental generation to the offspring, is called as
