Why did Gregor Mendel study pea plants and what did he discover?

Around 1854, Mendel began to research the transmission of hereditary traits in plant hybrids. Mendel chose to use peas for his experiments due to their many distinct varieties, and because offspring could be quickly and easily produced.

What did Mendel observe in his pea garden that led him to question the theory of blended inheritance?

Mendel noticed plants in his own garden that weren’t a blend of the parents. For example, a tall plant and a short plant had offspring that were either tall or short but not medium in height. Observations such as these led Mendel to question the blending theory.

What did Mendel use to identify genes?

The term Mendel used for genes are traits and these traits were later termed as genes. The genes are specific sequences of DNA that code for a particular protein.

Why did Mendel select garden pea plant for his experiment?

Mendel choose pea plants for his experiments because of the following reasons: (i) The flowers of this plant are bisexual. (ii) They are self-pollinating, and thus, self and cross-pollination can easily be performed. (iv) They have a shorter life span and are the plants that are easier to maintain.

What does heredity do in probability?

In genetics, theoretical probability can be used to calculate the likelihood that offspring will be a certain sex, or that offspring will inherit a certain trait or disease if all outcomes are equally possible. It can also be used to calculate probabilities of traits in larger populations.

Is female Homogametic?

In many species, including humans, the male is heterogametic and carries an X and Y sex chromosome while females are homogametic and carry two copies of the X chromosome.

What is male Heterogamety give an example?

Male Heterogamety includes human males having XY sex chromosomes and males of some insects having XO sex chromosome. Female Heterogamety includes the females of some species of birds, fishes, and insects.
