The video explains genetic characteristics, focusing on how traits like eye color and blood type are determined by alleles inherited from parents. It describes the structure of chromosomes and the concept of alleles, and differentiates between homozygous and heterozygous organisms based on allele similarity.

How many groups of chromosomes do human cells contain?

• One group from each parent

• Recessive

• Homozygous

What does it mean if an organism is heterozygous for a characteristic?

• It has more than two alleles

• It has two different alleles

• It has two identical alleles

• It has no alleles

From where does an organism inherit its alleles?
