A pure breeding tall pea plant was crossed to dwarf plant. What will be frequency of dwarf plants in F2?
Temka [501]

Tall pea plant was crossed to dwarf plant. The frequency of dwarf plants in F2 will be 0%.

  • A true breeding pea plant is one that, after self-fertilization, only bears offspring with the same traits.
  • True breeding organisms are those that share the same genes for the desired traits and are genetically comparable.
  • These animals possess homozygous alleles. If the alleles are distinct, only one of the gene's alleles—referred to as the dominant gene—will be expressed.
  • The other allele, referred to as the recessive one, has no effect.

According to the given cross:

                                  TT  X  tt   (parents)

                                 Tt Tt Tt Tt  (offspring) all tall

Hence the percentage of dwarf individuals is 0.

20 POINTS - MONOHYBRID CROSS
Stella [2.4K]
Both parents' genotypes are Bb (brown blue)
the punnet square would be
BB(kid one) Bb(kid two) Bb(kid three) bb(kid four)
kid one will be homozygous for brown eyes. kid two and three will be heterozygous for brown eyes. kid four will be homozygous for blue eyes

in other words, 75% will have brown eyes. 25% will have blue eyes
