Introduction
The study of genetics and inheritance has intrigued scientists for centuries. Gregor Mendel, often referred to as the “Father of Genetics,” laid the foundation for understanding inheritance patterns through his experiments with pea plants. Today, modern geneticists continue to build upon Mendel’s work, exploring the complexities of genetic inheritance. The Amoeba Sisters, known for their engaging and informative science videos, offer a Video Recap on Monohybrid Crosses & Mendelian Inheritance. In this article, we delve into the world of genetics, explore monohybrid crosses, and present a comprehensive answer key to aid students in mastering this fascinating topic.
Understanding Monohybrid Crosses and Mendelian Inheritance
Monohybrid crosses are a fundamental concept in genetics, focusing on the inheritance of a single gene between two individuals. Gregor Mendel’s work with pea plants demonstrated that certain traits are dominant and others recessive, and they follow predictable patterns in offspring.
Mendelian inheritance refers to the principles Mendel established, which include:
- Law of Segregation: During gamete formation, the two alleles for a gene segregate, with each gamete carrying only one allele.
- Law of Independent Assortment: Genes for different traits assort independently of each other during gamete formation.
- Dominant and Recessive Traits: Dominant alleles mask the expression of recessive alleles when present in heterozygous individuals.
