Introduction to Genetics Quiz

What is the primary focus of genetics?

• The study of heredity and trait transmission

• The study of animal behavior

• The study of environmental changes

• The study of plant growth

Who is known as the father of genetics?

• Albert Einstein

• Gregor Mendel

• Charles Darwin

• Isaac Newton

Why were pea plants ideal for Mendel's experiments?

• They grow quickly

• They require little water

• They have both male and female organs

• They are resistant to diseases

What is the P generation in Mendel's experiments?

• The first generation of offspring

• The generation with mixed traits

• The parental generation

• The second generation of offspring

In Mendel's experiments, what was observed in the F1 generation?

• Offspring were a mix of purple and white

• All offspring were purple

• All offspring were white

• Offspring had new colors

What did Mendel conclude about the presence of different versions of genes?

• Genes are only found in animals

• There are different versions of genes called alleles

• Genes are identical in all organisms

• Genes do not affect traits

What does it mean if an organism is homozygous?

• It has three alleles

• It has no alleles

• It has two identical alleles

• It has two different alleles

What is the difference between genotype and phenotype?

• Genotype is only found in plants

• Genotype is the genetic makeup, phenotype is the physical appearance

• Genotype is the physical appearance, phenotype is the genetic makeup

• Genotype and phenotype are the same

In a genetic cross, what does a dominant allele do?

• It is always masked by recessive alleles

• It has no effect on the organism

• It determines the organism's appearance if present

• It only appears in the second generation

In the practice problem, what is the dominant trait?

• Tall

• Wide

• Short

• Medium
