Question

When are red-flowered homozygous plants crossed with a homozygous white flower plant. What color is produced in the F1 Generation?
A) Red
B) White
C) Pink
D) Red and White

Answer 1

Hint: Whenever dominant and recessive character plants are crossed in a hybridization experiment, the plants produced in the F1 or Filial progeny always resembles the trait of either one of their parents, and the trait of another parent is not seen.

Complete answer: The color of the flower of the pea plant, the red color flower resembles the dominant character (the expressed character) whereas the white color of the flower resembles the recessive character (the unexpressed character in a dominant-recessive pair)

In the F1 generation,
The genotype of all the plants is Rr (heterozygous).
The phenotype of all the plants is red.
After crossing both the plants. The plants in the F1 generation bear all red flowers. The genotype of the parent red flower is RR because it possesses the dominant character for the flower color and the genotype of the parent white flower is rr because it possesses the recessive character for the flower color. The gametes produced by the red flower is either R or R and by the white flower is either r or r. As a result of the hybridization experiment, we are obtaining all the offspring’s genotypes as RR and its phenotype is observed as all red flowers.
Hence, their genotypic and phenotypic ratio is 100%. Thus, option A is the correct answer

Note: Based on these observations, Mendel proposed that something was being stably passed down unchanged from parents to offspring through gametes over successive generations (F1 & F2). He called these things factors. Now it is popularly known as' Gene'.
