heredity
atoms
molecules
Different version of genes are called
Proteins

Alleles
This trait is physically seen in an organism even if ONLY 1 copy is present
allele
recessive allele
dominant allele
genotype
This trait is NOT physically seen in the phenotype if the dominant allele is present
allele
recessive allele
dominant allele
genotype
This chart shows all the possible combinations of alleles that can results from a genetic cross. This is called a/an
dominant allele
recessive allele
punnett square
mitosis
The mathematical chance than an event will occur is called
accident
probability
An organism's physical appearance or visible traits (what it looks like)
genotype
phenotype
An organism's genetic makeup, or allele combination. The letters we use to show the allele combination
Genotype
Phenotype
When an organism has 2 identical/2 of the same alleles for a gene. For example, HH or hh
Or 2 alleles for the SAME color hair
Homozygous
Heterozygous
An organism has 2 different alleles for a gene. For example, Hh or
1 allele for blonde hair & 1 allele for black hair
Homozygous
