Which of the following is responsible for an organism or species becoming better suited to its environment?

• .Dichotomous Key

• Phylogeny

• Adaptation

The Golden Retriever was homozygous, the owners knew that this meant:

• having two identical alleles of a particular gene or genes.

• having two different alleles of a particular gene or genes.

Heterozygous dog breeds are less valuable than Homozygous breeds. Why is this?

• Homozygous breeds are less pure than Homozygous breeds.

• Hetero breeds are less pure than Homozygous breeds.

• Both breeds are of equal value.

Arise by mutation and are found at the same place on a chromosome.

• Allele

• Genotype

• Phenotype

This phenotype can be observed in individuals:

• BB

• AA

• eye color

  Gregor Mendel is known as the father of _________________ :

• Bacteria

Chromosomes carry __________________ in the form of genes.

• Bacteria

• Amazon Packages

This relies on the process of natural selection:

• Alleles

• Evolution

•  Overproduction

Due to natural selection, organisms adapt to their environment and have a 

• Higher chance of survival

•  Lower chance of survival 

A bug with three eyes instead of two is an example of:

• Competition

•  Limited Resources

• Mutation
