The physical trait is known as

Phenotype

100

A grid that uses letters to represent alleles and predict possible outcomes.

Punnett Square

100

When there is a blend of two traits, it is known as

incomplete dominance

200

Using the letter T, show what it means to be homozygous recessive.

tt

200

The letters we use to represent a trait is known as 

Genotype

200

A capital letter represents ____

A dominant allele

200

A dog breed well known for having spots most likely shows what non-mendelian behavior

codominance

300

In codominance and incomplete dominance the alleles are neither ________ or _________.

dominant or recessive

300

The different options a gene might have is known as 

alleles

300

Crossing an organism with TT with an organism that has tt would result in how many possible outcomes?

one (Tt)

300

Multiple alleles mean

There is more than one allele option for a trait.

400
Another name for homozygous would be

purebred

400

Genes always come in ______

Pairs or homologous pairs
400

The percent chance the offspring has of being dominant in the cross Tt x Tt.

75%

400

Hair color, eye color, and skin color have tons of possible outcomes. Why is this?

Polygenic inheritance. They are controlled by more than one gene.

500

Both of Mrs. Allen's parents are right handed, yet two of their daughters are left handed. Create a Punnett Square to show how this is possible.

Both parents are heterozygous dominant for right handedness.

500

If an organism has one of each allele it is known as 

heterozygous

500

In the cross Tt x TT there is a ____ percent chance of the offspring being homozygous recessive.

0%
