Question

Q. A pea plant with red flower (a Hybrid) crossed with a pea plant with white flowers. The
gene that controls the red flower is dominant against the gene that controls the white flower.
1. Show the genetic material in the gamete and the final filial generation.
2. What is meant by dominant and recessive gene?
3. What is the ratio of pea plant having red flowers to white flowers in the first filial generation​

Answer 1

Answer:

1)They produce pollen, which contains the male gametes (sperm). ... The offspring of the P1 generation are the F1 generation (first filial).

2) Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.

3) The first generation of offspring, the first filial generation, is the F1 generation. Mendel found that these plants all had purple flowers. The F1 generation was crossed with itself. The next generation, F2 generation, had a 3:1 ration of purple to white flowers.
