Are there any genes that control toe length?

This is sometimes said to controlled by one gene with two alleles, with the allele for S dominant to the allele for L. There is no good evidence for this myth; the small number of studies of toe length give contradictory results. Toes ranging from big toes longer (upper left) to big toe shorter (lower right).

How is the size of the big toe determined by genetics?

Conclusion. Whether the big toe is longer or shorter than the second toe is influenced by genetics, but it may be determined by more than one gene, or by a combination of genetics and the environment. You should not use toe length to demonstrate basic genetics.

Is the toe length a myth or a fact?

Toe length: The myth. This is sometimes said to controlled by one gene with two alleles, with the allele for S dominant to the allele for L. There is no good evidence for this myth; the small number of studies of toe length give contradictory results.

Which is more dominant, tall height or recessive trait?

For this reason, the dominant versions will always win over the weaker ones. For better understanding, let’s say “T” represents the tall height allele and “t” represents dwarfism allele. Following this, the tall height gene will be “TT” that is 2 copies of a similar allele or “Tt” that is a copy of each allele.
