How Gregor Mendel use pea plants for his experiment on heredity?
Mendel realised by using his pea plants that the offspring did not ( necessarily) show a mixing of genetic traits as previously beleived, but would show a parents traits ( this was before DNA and the study of HOW it was inheritied). Just to point out, Mendel used traits which we call complete dominance where you need only 1 version ( allele) of the dominant trait to show the dominant phenotype ( what it looks like). We show dominant alleles as CAPITAL LETTERS eg R, T, H, or whatever letter you are using and recessive alleles as little letters…..NOTE: the SAME letter as the dominant eg r,t or h. For example T= tall ( dominant trait) and t=short We have TWO copies of EVERY gene….one from each parent….so if you use T and t….the different combinations of these alleles are TT, Tt or tt. Mendel used this and when you use punnet squares you can calculate the estimated ratios or percentages of offspring you would expect to have a particualr trait. eg If you have parent 1 TT and parent
