Get Answers to all your Questions
(a) If we cross pure-bred tall (dominant) pea plants with pure-bred dwarf (recessive) pea plants we get pea plants of generation. If we now self-cross the pea plants of
generation, then we obtain pea plants of
generation.
(i) What do the plants of generation look like?
(ii) What is the ratio of tall plants to dwarf plants in generation?
(iii) State the type of plants not found in generation but appeared in
generation, mentioning the reason for the same.
(b) What are homologous structures? Give an example. Is it necessary that homologous structures always have common ancestors?
Answers (1)
(a) F1? plants: All tall (the dominant trait)
(b) F2? generation= 3 tall : 1 dwarf
(c) F1? plants do not exhibit dwarfism as presence of dominant allele (T) in monohybrid (Tt) mask the expression of rececssive allele (t). Two factors for a trait (alleles for tallness and dwarfism), present together in a heterozygous individual (Tt), do not get mixed and are separated during gametogenesis and exhibited in F2? generation.
