A botanist has acquired a group of sweet pea plants. All of the plants have yellow pea pods (the recessive trait), except for on
Advocard [28]

Answer:

In order to find out the genotype we do a testcross of green pea pods with yellow pea pods.

Explanation:

1. If the F1 generation consist of green pea pods only then the genotype of the green pea pod is 'GG' (i.e the dominant alleles).  

<h2>                           TEST CROSS </h2>

                    Green pea pods        X           Yellow pea pods

                                    GG              X              gg

       <u>Gametes: </u>

                                     G               X                g

      <u> F1 Generation: </u>

<h2>                                 Gg </h2>

2. However if the F1 generation consist of 50% green pea pods and 50% yellow pea pods then the genotype of green pea pods is 'Gg' (both the dominant and recessive alleles).

                   Green pea pods        X           Yellow pea pods

                               Gg                  X               gg

       <u>Gametes: </u>

                           G      g      X        g

       <u>F1 Generation:</u>

<h2>                              Gg, gg </h2>

We can relate this to Mendel's Law of segregation and meiosis as

  • Both the alleles segregate into seperate gametes (i.e they are sorted independent of one another).
  • This segregation is similar to the first division of meiosis in which homologous chromosomes of gene are segregated in daughter nuclei
