Genetics

Question 1

What is the study of biological inheritance patterns and variations in organisms called?

Answer 1

genetics

Genetics explores how traits are passed from parents to offspring.

Question 2

Define traits in the context of genetics.

Answer 2

Distinguishing characteristics passed from parent to offspring

Mendel is known as the ‘Father of Genetics’ for his work on inheritance.

Question 3

Who is known as the Father of Genetics?

Answer 3

Mendel

Mendel traced traits through generations by breeding pea plants.

Question 4

What method did Mendel use to study inheritance?

Answer 4

Controlled breeding using self-pollinating plants

He only used purebred plants that are genetically uniform.

Question 5

List the reasons why peas were chosen for Mendel’s experiments.

Answer 5

• They reproduce quickly
• Mating can be easily controlled
• Many traits are easily observed (e.g., flower color, pea shape, pea color)

These factors made peas ideal for studying inheritance.

Question 6

What does the term cross refer to in genetics?

Answer 6

Mating of two organisms

This is a fundamental concept in studying inheritance.

Question 7

What does P stand for in Mendel’s experiments?

Answer 7

Parental generation

This is the initial generation from which offspring are produced.

Question 8

What does F1 represent in Mendel’s genetic studies?

Answer 8

First generation of offspring

This generation results from crossing the parental generation.

Question 9

What does F2 signify in Mendel’s experiments?

Answer 9

Second generation of offspring

This generation results from crossing two F1 organisms.
