Genes Concept Map
Phenotype
-
Example: The agouti color is more likely to be a mouse's fur color or phenotype because it's the dominant gene.
Genotype
Genotype genes are genes that aren't shown (usually a recessive gene) but are still in someones chromosome.
Example: One recessive, one dominant gene. Dominant gene is the one that'll be shown so the genotype gene is there meaning the person is heterozygous. They can still pass on a blue eye gene if they have brown eyes and a blue genotype.

Gregor Mendel
Gregor Mendel was a monk in the early 1800s who figured out basic hereditary. He tested pea plants and found out that their genes being passed on went by a pattern.
Recessive
Recessive genes are the genes that are usually not shown, because when there is one dominant gene, and one recessive gene present in a chromosome, the dominant gene will be the phenotype gene.
Dominant
Dominant genes are the genes that are more likely to be shown because when there is one dominant gene and one recessive gene, the recessive gene will be the genotype one.

Punnett Square
A punnett square is a table with four segments in it. Two on top, and two on the bottom. To use a punnett square you have to put the phenotype genes on one side and the genotype genes on the other. Then designate one of each different type of box for each parent. With this you will be able to figure out the probability of a baby having; for example blue eyes.

Reginald Punnett
Reginald Punnett is the person that the punnett square is named after. It's named after him because he created it. He wanted to have an easier way to find out how likely it is for something or someone to have a particular gene
