VP #2: Understanding Genetics with Mendel

Who is known as the Father of Genetics?

• Gregor Mendel
• Charles Darwin
• Isaac Newton
• Louis Pasteur

What was the common belief about offspring height from parents of different heights before Mendel's experiments?

• Height would not change

• Offspring would be shorter

• Offspring would be taller

• Offspring would be of medium height

What ratio did Mendel find in the offspring when he self-fertilized the F1 generation?

• 2:1

• 1:1

• 3:1

• 4:1

What did Mendel call the inheritable factors that we now know as genes?

• Alleles

• Inheritable factors

• DNA

• Chromosomes

What is the term for the different versions of a gene?

• Chromosomes

• Alleles

• Gametes

• Phenotypes

According to Mendel's law of segregation, how many alleles does each parent contribute to their offspring?

• 4

• 3

• 2

• 1

In a Punnett square, what does a capital 'T' represent?

• A recessive allele.
• A gene variant from the mother.
• A mutation

• A dominant allele.

What is the phenotype of an organism with one dominant and one recessive allele?

• The phenotype will be that of the dominant trait.
• The phenotype cannot be determined without environmental factors.
• The phenotype will be that of the recessive trait.
• The phenotype will be a mix of both traits.

What tool helps visualize the probability of genetic combinations?

• Punnett Square

• Genetic Grid

• Trait Table

• Mendel's Chart

What is the term for a trait that masks another trait?

• Recessive

• Dominant

• Blended

• Neutral
