Who is Gregor Mendel? g.In genetics, each trait is noted by a single letter (Ex. “T” for tall plants)

II. Who is Gregor Mendel? g.In genetics, each gene is noted by a single letter (Ex. “T” for height) h.Capital letters are used to show which is the dominant allele (copy of the gene) Ex. T = the tall allele (dominant) t = the short allele (recessive)
