What is this definition? 'A group of organisms that can reproduce with each other to produce offspring that will also be able to reproduce.'

What is this definition? 'Differences between organisms caused by differences in the DNA they inherit from their parents.'

• Environmental factors on the genotype makes changes in the phenotype in environmental variation.
• Crossing over results in variations.
• Species is the basic unit of classification.

What can cause variation?

• Genetic variations are caused by the changes in the genome of individuals. It occurs during the sexual reproduction.
• Environmental factors on the genotype makes changes in the phenotype in environmental variation.

What does variation mean?

Which of the following would increase the number of different alleles in a population?

Variation in a trait may be due to the change in genetic material. What do you call this type of change?

• Inversion and deletion are the type of mutation.
• Radiation can also cause mutation.

*Individual X: presence of a dimple
*Individual Y: no dimple
Which of the following factors causes the difference in the trait between the two individuals?
