What is A Theory?
• “a supposition or a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained.”

What is Theory of Segregation?
• Mostly states that a gene can form more than one way
• Organism inherit two alleles for each trait • An allele is a DNA sequence that codes for a
gene.• Alleles pairs separate which makes each cell
then left with one allele for each trait

Que Es la teoría de la segregación?
Mendel’s First LawGene can have different alleles/variantsGamete gets one allele of geneA gene can exist in more than one form.Organisms inherit two alleles for each trait.When gametes are produced (by meiosis), allele pairs separate leaving each cell with a single allele for each trait.When the two alleles of a pair are different, one is dominant and the other is recessive.

Testcrossing: genetic cross between a homozygous recessive individual and a corresponding suspected heterozygote to determine the genotype of the latter.

Allele pairs separate or segregate during gamete formation , and randomly unite once fertilized

Theory of Independent Assortment • describes how different genes independently separate from one another when reproductive cells develop
Ratio of 9:3:3:1 in Pea Plants
Dihybrid Cross: breeding experiment between P generation (parental generation) organisms that differ in two traits

If two alleles of a pair is different one is dominant and the other recessive
