Alleles

• Alleles are different forms of the same gene.

• Ex: There are genes that code for eyes, and alleles determine the color of our eyes

Alleles

• Organisms of the same species have alleles in the same places on their chromosomes.

• We inherit two alleles for each gene; one from each parent.

Open Ended

Why does the offspring bunny have green eyes?

(Vocab: alleles, genes, proteins, combination)

Multiple Choice

How do we get our alleles?

• We get both pair of alleles from one parent.

• We get one allele from each parent.

• We get a mixed version of both parents' alleles.

Genotypes

All the gene alleles are called a genotype.

If this was CS class, the genotype would be the lines of code.

Every person has their own unique genotype! (unless you have an identical twin)
