One reason for Mendel's success with genetic studies of peas was that he

used only hybrid pea plants

used peas with large chromosomes

studied large numbers of offspring

discovered the sources of variation in peas

Pairs of genes that control the same trait are known as

allelles

gametes

hybrids

loci
