Gregor Mendel “The Father of Genetics”
... Genes are inherited in pairs, one allele from each parent Homozygous: identical alleles Heterozygous: different alleles In a hybrid, only the dominant allele (T) will be expressed (or seen). The other allele is recessive (t). Alleles segregate (separate) from each other during gamete formation and r ...
