Genetic law of facial features genes

In the genetic project of the five senses, the complete double eyelid is also one of the invisible genetic projects, that is to say, if a child's genetic genes contain complete double eyelids, then his appearance will immediately present complete double eyelids. To sum up, if both parents have double eyelids, then the probability of children having double eyelids is higher.

Interestingly, some couples who cut double eyelids gave birth to pregnant children with single eyelids and small eyes in childhood, but as the children grow up, they will give birth to beautiful double eyelids, which is a genetic style that cannot be solved or changed.

Extended data:

As a genetic unit, genes are paired in somatic cells and are highly independent in heredity. Therefore, in the process of meiotic gamete formation, pairs of genes can be separated independently in hybrid cells without interfering with each other, and continue to show their respective functions in offspring through gene recombination. This law theoretically explains the universality of variation caused by hybridization and separation in biology.

In heterozygotes, alleles separate with the separation of homologous chromosomes during meiosis, enter two different gametes, and are passed on to offspring independently.
