The video explores Gregor Mendel's groundbreaking work on genetics through his experiments with pea plants. Mendel discovered the principles of inheritance, including dominant and recessive traits, by observing the traits of pea plant generations. The video explains key genetic concepts such as genes, alleles, genotype, and phenotype, and demonstrates how these concepts apply to gamete formation and genetic variation. The video concludes with a call to action for viewers to engage with the content on social media.

What concept did Mendel introduce to explain the inheritance of traits?

• Cells

• Chromosomes

• Genes

• Proteins

What does it mean if an allele is dominant?

• It is beneficial to the organism

• It is never expressed in the phenotype

• It is always expressed in the phenotype

• It is harmful to the organism

How are recessive alleles represented in genotype notation?

• With a lowercase letter

• With a capital letter

• With a number

• With a symbol

What does homozygous mean?

• Having two identical recessive alleles

• Both B and C are correct

• Having two identical dominant alleles

• Having two different alleles

If a plant is homozygous dominant for green pods, what is its phenotype?

• No pods

• Mixed color pods

• Green pods

• Yellow pods

What is the genotype of a plant that is heterozygous for tallness?

• None of the above

• tt

• Tt

• TT

What possible gametes can a heterozygous tall plant produce?

• Only T

• Only t

• Both T and t

• Neither T nor t

Why is it important for gametes to have variation?

• It ensures all offspring are identical

• It increases the chance of mutation

• It allows for genetic diversity in offspring

• It has no significant impact
