Question

A homozygous tall pea plant with purple flowers was crossed with a short plant with white flowers and F2 generation was raised. What will be the proportion of tall plants and short plants in F2 generation? Explain.

Answer 1

Hint: Gregor Mendel used pea plants for understanding inheritance. He selected pea plants because they were easy to produce, could be easily bred, and had many observable features, such as the colour of petals and the colour of peas.

Complete answer:
We can follow the dihybrid cross to understand this question.
There would be a phenotypic ratio of 9:3:3:1.
The tall phenotype is dominant and will also be displayed in the heterozygous state.

Pea plants were important for Gregor Mendel in helping him to consider the means by which characteristics are inherited between parent and offspring. He selected pea plants because they were easy to produce, could be easily bred, and had many observable features, such as the colour of petals and the colour of peas.
Note: His methodical hypothesis checking and careful application of statistical models to the study of biological inheritance is more durable than the pea data introduced by Mendel in 1862. Mendel developed mathematical hypotheses about trait inheritance from his first experiments with monohybrid crosses that he could verify with more complicated experiments on dihybrid and even trihybrid crosses. One of the most important contributions Mendel made to biology is this method of establishing statistical assumptions regarding inheritance data.
