Question

In the pea plants that Mendel studiod, purple/violet lowers are dominant to white flowers and yellow poas are dominant to green peas. The alleles designated for each phenotype are W for purple/hiolet flowers, w for white flowers, G lor yellow peas, and g for green peas. 1) You are provided two plants with the genotypes GgWw and g9ww. Indicate their corresponding phenotype. (1 point). 2) Now you must cross these plants together to yield an F1 generation. Write out the expected gametes for each parent. (2 points) GgWw gametes- ggWW gametes You will use Mendel's final two laws to generate their gametes. State the two laws and define them in the context of these parents Name of the Law and a one complete sentence description required. (2 points) Law 1 (name and description) - Law 2 (name and description) =

Answer 1

1. Since purple/violet colour of flowers is dominant over white colour of flowers and yellow colour of peas is dominant over green colour of peas. Therefore, the phenotype of the below given genotypes are:

GgWw= Yellow peas/Purple violet flowers.

ggWW= Green Peas/Purple violet flowers.

2. GgWw gametes= GW, gW, Gw, gw

ggWW gametes= gW

Law1= Law of segregation : According to this law two alleles for each character separate during gamete formation.

Law2: Law of independent assortment: According to this law, each pair of alleles separate from each other independently during gamete formation. For example Yellow pea colour is independent of purple/violet flower colour and thus forms combination with white flowers. Similarly, green pea colour is independent of White flower colour and forms combination with purple/violet flowers.
