What do genetic diagrams show?
The possible genes of offspring.
What does the term homozygous mean?
If an organism has 2 alleles for a particular gene the same.
What does the term heterozygous mean?

The allele for the characteristic that’s shown is called the dominant allele.
Marked by a capital letter.
What is a recessive allele?
Shown by using small letters.
How would an organism show a recessive characteristic?
Both its alleles must be recessive.
How would an organism show a dominant characteristic?
The alleles can display either CC or Cc, as the dominant allele overrules the recessive one of the organism is heterozygous.
What does genotype mean?
What alleles you have.
What does phenotype mean?
Means the actual characteristic.
What is a monohybrid cross?
