Gregor Mendel - father of genetics!

1. Gregor Mendel- father of genetics! Austrian Monk tended to the garden in the monastery now it is located in CZ

2. Performed Experiments Using garden peas because they…. • grow quickly • are hardy plants • self-pollinate  pure for each trait

3. Parental Generation or P1 generation All the offspring were tall ????? Called first filial or F1 generation

4. He then crossed two offspring from the F1 generation 3 tall offspring to each 1 short offspring 3:1 called F2 generation second filial generation Tall F1 X Tall F1

5. Explanation of his Results Dominant trait T or tall Recessive trait t or short ** trait is size that is the characteristic ** allele is variation of the trait ex. Tall or short

6. Pivotal Concept that Mendel hypothesized….. • Genes are always in pairs one half of the pair comes from the father the other half of the pair comes from the mother

7. P1 generation TT x tt explained using punnett squares • Genotype - • gene combination of the children • look at ancestors • Phenotype • what is looks like • use your eyes to detect

8. He then crosses 2 F1 Tt x Tt Genotypes - TT, tt, Tt Phenotypes - 3 tall :1 short F2 Monohybrid Phenotypic Ratio

9. Trait - characteristic allele - variation of a trait homozygous - 2 genes in the gene pair are the same heterozygous - 2 genes in the pair are different Purebred - homozygous hybrid - heterozygus genotype - gene combination phenotype - what it looks like Terms to Know !!!!
