What is the hybrid type of a pair of alleles?

heterozygus

300

What did Gregor Mendel observe in his genetics experiments?

pea plants

400

True or False: Mendel had children

False (Monks can't have children)

500

This is the passing of physical characteristics from parent to offspring.

Heredity

What characteristics was Mendel studying when he crossed the pea plants?

-stem height -color (yellow pea pods and green pea pods)

200

What is another word for homozygus?

purebred

300

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

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.

Gregor Mendel

Who is the father of genetics?

Gregor Mendel

200

This occurs when egg and sperm join to make offspring.

fertilization

300

This tool shows all of the possible outcomes of a genetic cross.

Punnett square

400

If a white flower and red flower are crossed, what color would the offspring be?

Pink...due to blending of the traits because of incomplete dominance in flower colors.

100

This is the study of heredity

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 occurs when 2 traits are neither dominant nor recessive, both show up.

co-dominant / codominance

500

Neither trait is dominant over the other and the two blend together.

Incomplete Dominance

5

100

True or False: TT is heterozygus

False

200

This is an organism's physical appearance.

Phenotype

300

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

500

Factors that control traits are called.....

Genes
