1

200

What is another word for heterozygous?

hybrid

300

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

Plants / pea plants

400

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

Probability

500

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

Heredity

Genetics 2

100

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

-color (yellow pea pods and green pea pods)

200

What is another word for purebred?

homozygous

300

An organism with 2 different kinds of allele 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.

Gregor Mendel

Genetics 3

100

What is 1/4 in percentage form?

25%

200

Different forms of a gene are called?

Alleles

300

This 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.

500

What is the probability that these parents will have pass on a recessive phenotype? Bb + Bb

25%

Genetics 4

100

This is the study of heredity

genetics

200

This is an organism's genetic makeup, for example Bb.

Genotype

300

This term describes 2 different kinds alleles for a trait (Bb)

Heterozygous

400

This occurs when 2 traits are both dominant (BW)

co-dominant / codominance

500

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

Incomplete Dominance

Genetics 5

100

TT and tt are both examples of a ___________ trait.

purebred/homozygous

200

This is an organism's physical appearance.

Phenotype

300

What happens when a recessive allele is paired up with a dominant allele?

The recessive is hidden / doesn't show up

400

This type of genotype has 2 recessive alleles for a trait (bb)

Homozygous recessive

500

The "instructions" that control traits are called.....
