In pea plants, yellow seeds are dominant over green. If the heterozygous yellow-seeded plant is crossed with the green-seeded plant, what ratio of the yellow and green seeded plant would you expect in the F1 generation?

In a typical monohybrid cross, the F2 generation is written as 3:1 for phenotype but expressed as 1:2:1 for genotype. Explain with the help of an example.

Two independent mono-hybrid crosses were carried out involving a tall pea plant and a dwarf pea plant. In the first cross, the offspring population had an equal number of tall and dwarf plants, whereas in the second cross it was same. Work out the crosses and explain giving reasons for the differences in the population.
