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.

If Phoenix, Arizona, experiences a cool, wet day in June (when the weather is usually hot and dry), does that mean the region’s
Nuetrik [128]
Yes, the region is probably experiencing climate change. This is due to impact of several practices that humans do to the environment. The melting of the polar ice caps and the direction of the wind passes through these states affecting or changing its weather. If humans keep doing this mother nature, humans will be left with a planet that's constantly changing and possibly inhabitable.
