Answer:
⭕ Monohybrid Cross By Mendel : ⭕ At first Mendel crossed pure bred tall pea plant with pure bred dwarf pea plant.And He observed that only tall plants were produced in the first filial generation.✔️ ⭕ From this he concluded that traits are inherited independently.
Answer:
The F1 generation has the genotype Tt which is why all the plants are tall in height since all of them contain the allele for tall height (dominant allele).
In the presence of a dominant allele, the recessive allele is not expressed when all the plants have tall height. But when the plants of this generation are self-crossed we get the following genotypes in the new generation: TT : Tt : tt in the ration 1:2:1. Hence 25% of the plants have both the alleles as the recessive allele. When the dominant allele is absent the recessive allele is expressed in the plant is short in height. The recessive allele was suppressed in the F1
generation but expressed in the F2generation.
