Mendelian Genetics

Dominant TraitsUsually expressed with a caplital letter (Ex. T) this trait trumps the recessive trait and will be shown in the phenotype

PhenotypeThis is what the offspring look like (Ex. Tall plant)GenotypeThis is what the genes read (Ex. Tt)

Why did Mendel use pea plants?1. One replication cycle produces many offspring!2. Pea plants have short growth cycles (No waiting years to get your results)

Recessive traitsUsually expressed with a lower case letter (Ex. t) these traits will only show in a phenotype if accompnied with another recessive allele

Mendel is awesome!

Lets test your understanding:What offspring would you get if you crossed a Tt X Tt?
