Questions and Answers

What is variation?

The differences that exist between different species
The differences that exist between members of the same species (correct)
The similarities that exist between different species
The similarities that exist between members of the same species

How is variation increased?

Through mutation, as it introduces new genes into the population
Through sexual reproduction, as it combines genes from separate parents (correct)
Through genetic drift, as it leads to more pronounced variations
Through asexual reproduction, as it allows for more genetic diversity

What contributes to the increase in variation?

Combining genes from separate parents (correct)
Mutations occurring in the genetic code
Inheriting genes from only one parent
Having identical genes from both parents

Why does sexual reproduction lead to increased variation?

Due to the combination of genes from two separate parents (C) Signup and view all the answers

Explain the concept of variation and how it relates to members of the same species.

Variation refers to the differences that exist between members of the same species. These differences can include physical attributes such as height, hair color, and eye color among individuals. Signup and view all the answers

How does sexual reproduction contribute to the increase in variation?

Sexual reproduction increases variation by combining genes from separate parents, leading to a wider genetic diversity within the offspring. Signup and view all the answers

What is the role of genes in relation to variation?

Genes from separate parents contribute to the genetic diversity and physical differences observed in members of the same species. Signup and view all the answers

Why is variation considered to be increased through sexual reproduction?

Variation is increased through sexual reproduction because it allows for the combination of genes from separate parents, leading to a wider genetic diversity within the offspring. Signup and view all the answers

What is the significance of variation in the context of inheritance and genetic diversity?

Variation plays a crucial role in inheritance and genetic diversity as it contributes to the diversity of traits within a species, allowing for adaptation and survival in changing environments. Signup and view all the answers

Study Notes

Variation and Inheritance

Variation refers to the differences that exist between members of the same species.
Examples of variation include physical differences such as height, hair color, and eye color.
Variation is increased through sexual reproduction, which combines genes from separate parents.
During sexual reproduction, individuals inherit genes from both parents, e.g., some genes from the mother and some from the father.
