Question

Which of the following is an incorrect statement about Gregor Mendel?
A) He conducted hybridisation experiments on sweet peas for seven years from 1856 to 1863.
B) He applied statistical analysis and mathematical logic to solve problems in biology.
C) His experiments had a small sampling size.
D) Mendel initially selected pea plants with contrasting characters.

Answer 1

Hint: Plant height, pod form and colour, seed shape and colour, and bloom position and colour were among the seven features Mendel studied in pea plants. Mendel demonstrated, for example, that when a true-breeding yellow pea and a true-breeding green pea were crossed, the offspring always produced yellow seeds.

Complete answer:
The study of Gregor Mendel on peas led to our knowledge of inheritance's fundamental principles. As a result, he is known as the Father of Genetics. Gregor Mendel's work, like that of many other great artists, was not appreciated until after his death.

Mendel began his first set of hybridization experiments with the sweet pea in 1856, and continued for the next seven years, from 1856 to 1863. He was the first to answer biological problems using statical analysis and mathematical logic.

Because small sample sizes are prone to deviations caused by chance, his experiment had a big sampling size and he evaluated seven opposing qualities to pea plant to analyse. To avoid self-pollination in pea plants, he used procedures like emasculation and bagging in his experiment.

The Results of Mendel's Experiments
- The genotype refers to the plant's genetic makeup. Phenotype, on the other hand, refers to the plant's physical appearance.
- Alleles are pairs of genes that are passed down from parents to offspring.
- When the chromosomes are half during gametogenesis, one of the two alleles has a 50% chance of fusing with the other parent.
- Homozygous alleles are those with the same alleles, while heterozygous alleles are those with different alleles.

Note: The two tests resulted in the formation of Mendel's laws, often known as inheritance laws, which are as follows:
- Law of Dominance
- Law of Segregation
- Independent Assortment Law
