The study of heredity
Genetics
different forms of a gene
Allele
when the two alleles are the same for a certain trait
Homozygous
In the punnet square shown, what is the probability that the blue eye gene will show in the offspring?

50%
Create a punnet square for this mother (Mm) and father (MM) genotype for skin tone
M . m
M . MM Mm
M . MM Mm
Heredity
The type of allele that will will take over for a certain trait
dominant
When the two alleles are different for a certain trait
heterozygous
In the punnet square shown, what is the probability that the dominant gene for a yellow plant (Y) will show in the offspring?
