Survival of the Fittest

Squares
100

This word means that the two genes are different.

What is heterozygous? 

100

This tool is used to find the probability of the genotypes and phenotypes of a cross between two parents. 

What is a Punnett Square?

100

This is a trait that helps an organism survive in its environment.

What is an adaptation? 

100

This is the probability that a heterozygous dominant parent and a homozygous dominant parent will have a homozygous recessive baby. 

What is 0%?

200

This word means that the two genes are the same.

What is homozygous? 

200

This is at least two or more different forms of a gene.

What is an Allele?

200

This is the process of nature that allows the most well adapted to their environment, organisms survive. 

What is Natural Selection?

200

This is the probability that a homozygous dominant parent and a homozygous recessive parent will have a heterozygous baby.

What is 100%?

300

This genotype shows a recessive phenotype.

What is homozygous recessive? 

300

This is what trait shows. The physical traits that appear in an individual as a result of its genotype.

What is Phenotype?

300

This is the process of humans choosing which individuals in a species should pass on their traits based on human needs. Dogs are a good example of this.

What is Artificial Selection or Selective Breeding?

300

This is the probability that a homozygous dominant parent and a homozygous recessive parent will have a baby that shows the recessive trait.

What is 0%?

400

These genotypes show a phenotype for the dominant trait.

What are AA and Aa?

What are homozygous dominant and heterozygous?

400

An organisms genetic Makeup or allele combinations. Examples include homozygous dominant, homozygous recessive and heterozygous. 

What is a Genotype?

400

This is a random and rare change in DNA not passed down from a parent. 

What is a mutation?

400

What is the probability that a heterozygous parent and a homozygous recessive parent will have a baby who shows the recessive trait?

What is 50%?

500

This double helix structure codes for all your genes. This structure is also called deoxyribonucleic acid.

What is DNA?
500

This is a segment of DNA on a chromosome that codes for a specific trait. 

What is a gene?

500

This is the theory that species change over time through natural selection.

What is Evolution?

500

This is the probability that two heterozygous parents will have a baby who shows the dominant trait. 

What is 75%?
