Understanding Genetic Inheritance: How Genes Control Physical Characteristics

The video tutorial explains how genes and chromosomes from each parent influence the physical characteristics of offspring. It covers the concept of alleles, which are different forms of the same gene, and how they contribute to genetic variation. The tutorial also discusses chromosome pairs, gene expression, and the difference between homozygous and heterozygous organisms. It further explains dominant and recessive alleles, using fur color inheritance in mice as an example to illustrate these genetic principles.

Describe the inheritance pattern of fur color in mice as explained in the text.

What happens when an organism inherits two recessive alleles for a particular gene?
