Study the given data and answer the questions following the data.
i. What is the term for this type of cross?
ii. What does the data of the column market F1 indicate?
ii. Express the genotype of the (a) parent (b) F1 Progeny and (c) F2 Progeny
(i) The term for this type of cross is monohybrid cross. It is a type of breeding experiment in which homozygous plants are crossed for one character and then the offsprings are studied for genetics.
(ii) It indicates that the gene for red colour (R) is dominant over for white colour (r).
(iii) (a) The genotype of parents – RR (male plant) and rr (female plant)
Where, RR codes for red flower whereas rr codes for the white flower.
(b) The genotype of F1 – Rr (red)
(c) The genotype of F2 – RR( homozygous red), Rr ( heterozygous red) and rr (homozygous white)

The genotype of green-stemmed tomato plants is denoted as GG and that of purple-stemmed tomato plants as gg. When these two are crossed,
i. What colour of stem would you expect in their F1 progeny?
ii. Give the percentage of purple-stemmed plants if F1 plants are self-pollinated.
iii. In what ratio would you find the genotypes GG and Gg in the F2 progeny?Xam idea - Science
How did Mendel explain that it is possible that a trait is inherited but not expressed in an organism?Xam idea - Science
In one of his experiments with pea plants, Mendel observed that when a pure tall pea plant is crossed with a pure dwarf pea plant, in the first generation, F1 only tall plants appear.
i. What happens to the traits of the dwarf plants in this case?
ii. When the F1 generation plants were self-fertilised, he observed that in the plants of the second generation, F2 both tall plants and dwarf plants were present. Why it happened? Explain briefly.Xam idea - Science
