 * //DEFINITIONS!!://**


 * Genetics**- the branch of Biology that focuses on heredity.


 * Parental Generation** (P1**)-** First two individuals breeded


 * First Filial Generation (F1)-** Offspring of P1


 * second filial Generation (F2)-** the offspring of F1, after self polinating!!


 * Homozygous-** if the two alleles that are present for a particular gene are the same, the individual is homozygous for that trait.


 * Heterozygous-** If the two alleles are different, the individual is call heterozygous for that trait.


 * Gregor Mendel-** Mendel is the father of genetics


 * Mendel's Law of Segregatio****n**- The two alleles for a trait separate during gamete formation.


 * Mendel's Law of Independent Assortment**- The chromosomes line up independently. The inheritance of one trait is not influenced by any other traits becuse the tetrads and chromosomes line up independently.


 * Dominant and Recessive Alleles-** Each trait is represented by a letter. the dominant allele is expressed by a capital letter. the recessive allele is expressed by a lower case letter.


 * Monohybrid Cross**- A cross that involves one trait.




 * Punnett Square**-A diagram that predicts the outcome of a cross by showing all the possible genotypes and phenotypes. The genotype of the parent are written across the top and down the left side.


 * ex. of a Punnett Square:**


 * Dihybrid Cross-** is a cross that involves two traits.
