In pumpkin, the white color of the fruit is determined by the W gene, the color is w, the disc-shaped shape of the fruit is S, the spherical is s. By crossing a plant with white disc-shaped fruits with a plant with white disc-shaped fruits, we obtained: 28 plants with white disc-shaped fruits, 9 – with white globular fruits, 10 – with yellow disc-shaped fruits and 3 – with yellow globular fruits. Determine: 1) the genotypes of the crossed plants; 2) the phenotype of the offspring obtained as a result of self-pollination of plants of each genotypic class.

1) Genotypes P: (female) WwSs, (male) WwSs;
2) a) the offspring obtained as a result of self-pollination of plants with the WWSS genotype has white disc-shaped fruits;
b) the offspring obtained as a result of self-pollination of plants with the WWSs genotype has white disc-shaped and white spherical fruits in a ratio of 3: 1;
c) the offspring obtained as a result of self-pollination of plants with the WwSS genotype has white disc-shaped and yellow disc-shaped fruits in a ratio of 3: 1;
d) the offspring obtained as a result of self-pollination of plants with the WwSs genotype has white disc-shaped, white spherical, yellow disc-shaped and yellow spherical fruits in a ratio of 9: 3: 3: 1;
e) the offspring obtained as a result of self-pollination of plants with the WWss genotype has white spherical fruits;
f) the offspring obtained as a result of self-pollination of plants with the Wwss genotype has white spherical and yellow spherical fruits in a ratio of 3: 1;
g) the offspring obtained as a result of self-pollination of plants with the wwSS genotype has yellow disc-shaped fruits;
h) the offspring obtained as a result of self-pollination of plants with the wwSs genotype has yellow disc-shaped and yellow spherical fruits in a ratio of 3: 1;
i) the offspring obtained as a result of self-pollination of plants with the wwss genotype has yellow spherical fruits.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
