Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Chromosome Theory of Inheritance

The chromosome theory of inheritance posits that genes are located on chromosomes, which are the carriers of genetic information. This theory integrates the principles of Mendelian genetics with the understanding of cellular biology, establishing that the behavior of chromosomes during meiosis explains the inheritance patterns observed by Gregor Mendel.

Mendelian Genetics

Mendelian genetics refers to the set of principles derived from Gregor Mendel's experiments with pea plants, which established the laws of segregation and independent assortment. These laws describe how alleles segregate during gamete formation and how different traits are inherited independently, laying the groundwork for modern genetics.

Meiosis

Meiosis is a specialized form of cell division that reduces the chromosome number by half, resulting in the formation of gametes (sperm and eggs). This process is crucial for sexual reproduction and ensures that offspring inherit a combination of genes from both parents, aligning with Mendel's observations of trait inheritance.
