Genetics Concepts and Terminology

The video introduces genetics, focusing on heredity and Gregor Mendel's contributions. It explains traits, alleles, and the concepts of dominant and recessive alleles. The video also differentiates between genotype and phenotype, providing examples to illustrate these genetic principles.

Who is considered a key figure in the study of genetics?

• Charles Darwin

• Gregor Mendel

• Albert Einstein

• Isaac Newton

What was one of Mendel's key conclusions from his experiments?

• Traits are passed from one generation to the next

• All alleles are dominant

• Alleles do not affect traits

• Traits are not passed from one generation to the next

What is a trait?

• A type of DNA

• A type of plant

• A specific characteristic like hair color

• A type of gene

Where are genes found?

• On the skin

• In the air

• In water

• On DNA

What is a dominant allele?

• An allele that is always recessive

• An allele that always shows up as a trait

• An allele that is never inherited

• An allele that never shows up

How is a dominant allele represented?

• With a capital letter

• With a symbol

• With a lowercase letter

• With a number

What does homozygous mean?

• Having two different alleles for a trait

• Having three alleles for a trait

• Having two of the same alleles for a trait

• Having no alleles for a trait

What does heterozygous mean?

• Having three alleles for a trait

• Having no alleles for a trait

• Having two of the same alleles for a trait

• Having two different alleles for a trait

What is the phenotype?

• The genetic makeup

• The physical characteristic

• The DNA sequence

• The allele type

What is the genotype?

• The genetic makeup

• The DNA sequence

• The physical characteristic

• The allele type
