Exploring Mendelian Genetics Concepts

The video tutorial covers Mendelian genetics, focusing on Gregor Mendel's experiments with pea plants. It explains the blending hypothesis and how Mendel's work disproved it, leading to the discovery of dominant and recessive traits. The tutorial details Mendel's laws of segregation and independent assortment, highlighting chromosome behavior during meiosis. It also provides guidance on solving genetics problems using Punnett squares and probability calculations.
