Transcript of Why do we resemble our parents?

Can we get a mix of one trait from our parents?
You can get different traits from your parents but genes don't mix. For example, if one parent is tall and one is short, that doesn't mean you will be average height. You will recieve the dominant trait.
Why do we resemble our parents?
Alleles are the "form" of a gene. A pair of alleles is called a genotype.
What is a dominant trait?

A dominant trait is the trait that will appear in the offspring over the recessive trait received from the other parent.
What is a recessive trait?
A recessive trait is a trait masked by the dominant trait unless the gene is homozyous and there are 2 recessive alleles.
Do all genes come in pairs?
All genes come in pairs. A purebred organism will have two of the same alleles and a hybrid will have a dominant and a recessive allele.
We resemble our parents because of genes we inherit from them. We get genes from both of our parents.
What are alleles?
