Topic 2 Lesson 1: Patterns of Inheritance

Who was the Austrian monk that experimented on pea plants and is called the "father of genetics"?

• Gregor Mendel
• Charles Darwin

• Francis Crick

• James Watson

Answer explanation

The Austrian monk Gregor Mendel is known as the "father of genetics" for his pioneering experiments with pea plants, where he established the basic principles of heredity.

What type of plant did Gregor Mendel experiment on?

• Corn plants

• Wheat plants

• Pea plants

• Rice plants

Answer explanation

Gregor Mendel is known for his foundational work in genetics, which he conducted using pea plants. He chose pea plants for their distinct traits and ease of cultivation, allowing him to study inheritance patterns effectively.

Why is Gregor Mendel known as the "father of modern genetics"?

• He discovered DNA

• He was the first to study human genetics

• He quantified his results and studied inheritance patterns

• He invented genetic engineering

Answer explanation

Gregor Mendel is known as the "father of modern genetics" because he quantified his results and studied inheritance patterns through his experiments with pea plants, laying the foundation for the field of genetics.

What does the P generation refer to in Mendel's experiments?

• Offspring

• Parents

• Grandparents

• Siblings

Answer explanation

In Mendel's experiments, the P generation refers to the 'Parents' of the offspring. This generation is crucial as it provides the initial genetic material for the subsequent generations studied.

What is the term Mendel used for alleles?

• Genes

• Chromosomes

• Factors

• Traits

Answer explanation

Mendel referred to alleles as "factors" in his work on inheritance. This term was used to describe the units that determine traits, which we now understand as genes.

How many alleles does an organism receive from each parent?

• Two alleles from each parent

• One allele from each parent

• Three alleles from each parent

• No alleles from parents

Answer explanation

An organism receives one allele from each parent, resulting in two alleles total for each gene. This is fundamental to Mendelian genetics, where alleles are inherited in pairs.

Different forms of a gene are called

• alleles.
• hybrids.

• dominant factors.

• recessive factors.

Answer explanation

Different forms of a gene are known as alleles. They represent variations in a gene's sequence, leading to different traits. The other options do not accurately describe these variations.
