FAQs on Inheritance of Two Genes: Linkage Video Lecture - NEET

1. What is the concept of inheritance of two genes?

Ans. Inheritance of two genes refers to the transmission of genetic traits from parents to offspring through the passing of two specific genes. These genes can be inherited together if they are located close to each other on the same chromosome, a phenomenon known as genetic linkage.

2. How does genetic linkage occur?

Ans. Genetic linkage occurs when two genes are located near each other on the same chromosome. During the process of meiosis, which is the formation of sex cells (gametes), these genes tend to be inherited together more often than not. However, the degree of linkage can vary depending on the distance between the genes on the chromosome.

3. What is the significance of studying genetic linkage in inheritance?

Ans. Studying genetic linkage helps us understand how certain traits are inherited and how they are passed down through generations. It allows us to map the location of genes on chromosomes and determine their relative positions. This knowledge is crucial in fields such as genetics, breeding, and disease research.

4. How does genetic linkage affect genetic diversity?

Ans. Genetic linkage can influence genetic diversity by reducing the likelihood of genetic recombination between linked genes. When genes are closely linked, they are less likely to undergo independent assortment during meiosis, resulting in a lower degree of genetic variation. On the other hand, genes that are farther apart on the chromosome have a higher chance of recombination, leading to increased genetic diversity.

5. Can genetic linkage be broken?

Ans. Yes, genetic linkage can be broken through a process called recombination or crossing over. During meiosis, homologous chromosomes can exchange genetic material, resulting in the shuffling of genes between chromosomes. This can lead to the separation of previously linked genes and the creation of new combinations, increasing genetic diversity. The frequency of recombination depends on the distance between the genes on the chromosome.
