Exploring Basic Mendelian Genetics Concepts

Who is considered the father of modern genetics?

• Isaac Newton

• Gregor Mendel

• Charles Darwin

• Albert Einstein

What unique feature of pea plants made them ideal for Mendel's experiments?

• Ability to grow quickly

• Ability to self-pollinate

• Resistance to diseases

• Brightly colored flowers

What term did Mendel use to describe plants that always produce offspring with the same traits?

• Cross breeding

• Dominant

• True breeding

• Hybrids

How many traits did Mendel examine in his pea plant experiments?

• Seven

• Five

• Three

• Ten

What did Mendel call the first generation of offspring in his experiments?

• P generation

• F1 generation

• F2 generation

• S generation

What was Mendel's second hypothesis about the F1 generation?

• They would be true breeding

• They would produce only recessive traits

• They would revert to the parent generation traits

• They would show new, unseen traits

What is the definition of an allele?

• A version of a gene

• A tool for breeding plants

• A type of pea plant

• A dominant trait

What does a Punnett square show?

• Possible genetic combinations

• The process of pollination

• The color of pea plants

• The height of pea plants

What is the phenotypic ratio of a cross between a homozygous dominant and a heterozygous pea plant?

• 1 tall : 3 short

• All short

• 3 tall : 1 short

• All tall

In a cross between a heterozygous yellow seed plant and a homozygous recessive green seed plant, what is the phenotypic ratio?

• All yellow

• 3 yellow : 1 green

• 1 yellow : 1 green

• All green
