Exploring Sexual Reproduction and Genetic Variation

What process is responsible for the diversity of traits in biological families?

• Environmental factors

• Asexual reproduction

• Genetic mutation

• Sexual reproduction

How many chromosome pairs do humans have?

• 23

• 46

• 22

• 24

What term is used to describe organisms with two sets of chromosomes?

• Polyploid

• Monoploid

• Diploid

• Haploid

During fertilization, what type of cells fuse to form a new organism?

• Somatic cells

• Gametes

• Stem cells

• Blood cells

What is the chromosome count in a human haploid gamete?

• 46

• 23

• 24

• 22

Why is sexual reproduction important?

• It creates genetic variation and diversity

• It allows organisms to produce offspring

• None of the above

• Both A and B

What does the diagram illustrating genetic variation show?

• The possible gametes and chromosome combinations in offspring

• The structure of a single chromosome

• The process of asexual reproduction

• The lifecycle of a plant

Why are siblings not genetically identical?

• They have different diets

• They are exposed to different environments

• They inherit different sets of chromosomes from their parents

• They have different lifestyles

What increases genetic variation even more during fertilization?

• Dietary changes

• Other genetic processes

• Genetic mutations

• Environmental factors

What makes each individual unique?

• Their lifestyle

• Their inherited set of chromosomes

• Their diet

• Their environment
