### Mendel's Second Law (Independent Assortment) Activity**Question:**Mendel's second law (independent assortment) has its basis in which of the following?1. ○ Alignment of homolog pairs at the equator2. ○ Separation of homologs at anaphase3. ○ Separation of cells at telophase4. ○ Crossing overPlease select the correct option to understand the principle underlying Mendel's second law of independent assortment and its connection to meiosis. Here are some key points related to each choice to help guide your understanding:1. **Alignment of homolog pairs at the equator:** - This occurs during metaphase I of meiosis. - Homologous chromosomes line up randomly at the cell's equatorial plane.2. **Separation of homologs at anaphase:** - This occurs during anaphase I of meiosis. - Homologous chromosomes are pulled apart to opposite poles of the cell. 3. **Separation of cells at telophase:** - This involves the final separation of the cells, resulting in two new cells at the end of meiosis I and II. 4. **Crossing over:** - This occurs during prophase I of meiosis. - Homologous chromosomes exchange segments to increase genetic diversity.Understanding Mendel's second law helps in comprehending how traits are inherited independently of each other, contributing to genetic variation.

Genetic Variation

Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.

Quantitative Genetics

Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
