Question

What is a Mendelian trait?

Answer 1

Hint: The Mendelian traits can be described at the level of the gene then the dominant and recessive traits exist. A dominant trait is a trait that appears first or expressed visibly in the organisms and a recessive trait or d trait is masked and not show itself in the organisms at the gene level.

Complete solution:
The seven traits that Mendel studied in pea are listed below:
-Type of seed shape i.e whether the seed is– round or wrinkled
-Seed color – yellow or green
-Colour of flower – purple or white
-Pod shape – inflated or constricted
-Pod color – green or yellow
-Position of flowers – axial or terminal
-Length of stem – tall or dwarf
Mendel presented his results in the year 1865 while experimenting on nearly 30,000 pea plants to the local natural history society, his results were based on the patterns he observed, the counting data he collected, and the mathematical analysis of his results.
- Mendel selected garden pea for his experiments due to the following characteristics:
- The first and the most important point which was there in the mind of Mendel is that garden peas need a shorter lifetime and are the plants that are easier to take care of.
- The pea plant pollinates on its own thus the process of self or cross-pollination can occur easily in between them.
-The physical features of the pea plant are easier to recognize and thus easier to study.
-The flowers of the pea plant are found to be bisexual consisting of both the male and the female part within the same flower.

Note:
Mendel proposed three laws of inheritance based on his experiments on the garden pea. These laws of inheritance were the law of dominance, the law of segregation, and the law of independent assortment. Later his work was discovered by three different scientists independently -that were Hugo de Vries, Carl Correns, and Tschermak. A.
