Question

Question 1 Matching The ________________________ hypothesis proposes that it is possible for all members of a species to die without leaving living descendents.

The ________________________ hypothesis proposes that groups of similar plants and animals share features because they inherited them from a shared ancestor.

In the process of ________________________, an ancestral species gives rise to two descendent species.

The ________________________ hypothesis proposes that the characteristics of species can change over time.

Darwin’s major contribution to evolutionary theory is the ________________________ hypothesis.

The study of ________________________ is the study of how traits are transmitted from parents to their offspring.

Mendel’s principle of ________________________ posits that the hereditary material is composed of discrete unchanging particles of inheritance.

Individuals who have two copies of the same allele at a locus are ________________________.

________________________ refers to changes in an individual’s DNA sequence induced by radiation, chemical agents, the action of viruses, or by errors during replication.

Speciation can only occur if there is a reduction in ________________________ among populations of a parental species

A. gene flow B. natural selection C. speciation D. DNA E. segregation F. homozygous G. transformation H. heterozygous I. common descent J. mutation K. extinction L. descent with modification M. heredity N. genetic drift

Answer 1

1. K. Extinction : it leads to end of the species.

2. I. Common descent

3. C. Speciation: it leads to formation of new species.

4. L. Descent with modification.

5. B. Natural selection.- Each organism adapts itself in the habitat.

6. M . Heredity

7. E. Segregation

9. F. Homozygous.

10. Mutation- changes in the genetic material.

11. A. Gene flow.
