1

200

What is another word for heterozygous?

hybrid

What did Gregor Mendel cross-pollinate in his genetics experiments?

Plants / pea plants

400

This is a number that describes how likely it is that an event will occur.

Probability

500

This process involves humans choosing which organisms get to reproduce based on desired traits.

Selective Breeding

When one parent has a homozygous dominant genotype and the other has a homozygous recessive genotype, what are the chances they have a child with a dominant phenotype?

100%

What is another word for purebred?

homozygous

300

An organism with 2 different alleles for a trait is called a ______.

Hybrid/heterozygous

400

This type of organism has 2 dominant alleles for a trait.

Homozygous dominant

500

This was the scientist who first began studying heredity and genetics.

Different forms of a gene.

alleles

Genetics 4

100

This is the study of how traits are passed from parent to offspring

genetics

200

This is an organism's genetic makeup.

Genotype

300

This type of organism has 2 different alleles for a trait

Heterozygous

400

This process causes organisms with better adaptations to survive and pass on their traits without human involvement.

Natural Selection

500

This process involves using technology to modify the genetic code for an organism to produce desired traits.

Genetic Modification

Genetics 5

100

TT and tt are both examples of a ___________ trait.

purebred/homozygous

200

This is an organism's physical appearance.

Phenotype

300

In Mendelian genetics, what happens when a recessive allele is paired up with a dominant allele?

It is hidden / doesn't show up

400

This type of organism has 2 recessive alleles for a trait

Homozygous recessive

Factors that control traits are called.....
