Question

Name the phenomenon in which no medium height plants are obtained in F1 generation upon crossing pure tall and pure dwarf plants

Answer 1

Law. Of dominance. (Mendal's 1st law)

Answer 2

This phenomenon is at par Law of dominance or Mendel’s 1st law.

Because there are only two types of genes present in the type of pea plant.

Out of the plant which is short that possess recessive gene and tall one which was dominant gene and thus all the outcome of plants were tall.

Mendel's Law of Dominance states that recessive alleles will always be covered or masked by dominant alleles.

Therefore, across breeding between a homozygous dominant and a homozygous recessive will always result or express the dominant phenotype plant, while still having a heterozygous genotype.
