Again, in F2 we see reappearing the high ancestral toe-numbers (practically lost in the heterozygotes of F1, table 12, b).
Do the 4-toed heterozygotes produce a larger proportion of imperfect dominants in F2 than the 5-toed heterozygotes?
Next, the heterozygotes of F1 (table 46), may be appealed to; but they will give no critical answer.
Some are probably matings of two heterozygotes, others of two recessives, and others still of a recessive with a heterozygote.
heterozygote het·er·o·zy·gote (hět'ə-rō-zī'gōt')
An organism that has different alleles at a particular gene locus on homologous chromosomes.
