A grid that uses letters to represent alleles and predict possible outcomes.
Punnett Square
When there is a blend of two traits, it is known as

Using the letter T, show what it means to be homozygous recessive.
tt
The letters we use to represent a trait is known as
Genotype
A capital letter represents ____
A dominant allele
A dog breed well known for having spots most likely shows what non-mendelian behavior
codominance
In codominance and incomplete dominance the alleles are neither ________ or _________.
dominant or recessive
The different options a gene might have is known as
alleles
Crossing an organism with TT with an organism that has tt would result in how many possible outcomes?
one (Tt)
Multiple alleles mean
There is more than one allele option for a trait.
purebred
Genes always come in ______
The percent chance the offspring has of being dominant in the cross Tt x Tt.
75%
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.
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.
If an organism has one of each allele it is known as
heterozygous
In the cross Tt x TT there is a ____ percent chance of the offspring being homozygous recessive.
0%
What is the opposite of non-mendelian genetics?
Simple dominance
