Question

Mendel published his research under the title of
A. Laws of heredity
B. Experiments in plant hybridisation
C. Hybridisation experiments on pea
D. My experiments on particulate inheritance

Answer 1

Hint: Gregor Mendel is also known as the ‘Father of modern Genetics’ was an Austrian scientist and Teacher who conducted experiments on garden pea hybrids. He drafted three laws which later on became the foundation of genetics.

Complete answer:
- Gregor johann mendal, conducted hybridization experiments on garden peas and first explained the principles of inheritance. Finally, the postulated law of heritance. This law of in-heritan in the book ‘Experiments’ on plants by hybridisation.
- Mendal worked with seven characteristics of pea plant: plant height, pod shape, a color seed shape and color, and color, and color flower position, and color. Taking seed color as an example.
- Mendel said that when a true-breeding yellow pea and a true-breeding green pea were cross-breed their offspring always produced yellow seeds. However, in the next generation the green peas reappeared at a ratio of 1 green pea to 3 yellow.
- To explain this phenomenon, Mendal conicalizes the terms ‘’recessive’’ and ‘’dominant’’ in reference to certain traits. In the preceding example, the green trait, which seems to have vanished in the first filial generation, is recessive and the yellow is dominant. He published his work in 1866, demonstrating the actions of invisible ‘’factor’’-now called gene in predictably determining the traits of an organism.

Hence the correct option is (C) Hybridisation experiments on pea.

Note: Mendel's experiments led to three laws, they were,
1. Law of dominance - The offspring will only inherit the dominant alleles.
2. Law of independent assortment - During gamete production a pair of traits segregate independently.
3. Law of segregation - During gamete production two copies of gene segregate so that the offspring has only one copy of each gene.
