How does cleft lip form?

Answer 1

cleft lip is passed on to other generations due to it being a recessive trait in some people. this means that the gene if not fully recessive will not show up in the physical appearance of the affected person. It is simple to figuer out if you use a Mendellian cross which for people who do not know what this is i will explain. Mendel was a Austrian monk that for years used pea plants to discover a way to find out how the genetics of humans and plants alike work. after years he formualted an equation called a Mendellian cross which is used to find sex-linked crosses, single and double gene crosses, the latter coming up with 16 results and the first haveing 4 results. Cleft lip can be found by using this cross by finding the requierd genes that cause this and if sex-linked can make the process easier. if this was sex-linked then a mendellian cross would show that the women have more of a chance to hide or conceal this deformity within the genetics and the men have a 1/2 chance of showing the physical dyformity and the other half being free of it. this is only based on my limited high school knowledge of bio genetics and may not be perfectly straight forword.

Answer 2

Cleft lip forms during fetal development when the tissue that makes up the upper lip does not completely close, resulting in a gap. This can be due to genetic factors, environmental factors, or a combination of both. Treatment usually involves surgical correction.

Answer 3

if yo mama & daddy has a dominate allele for cleft lip

Answer 4

when the frontonasal and maxillary processes fail to fuse

Answer 5

An embryo 4 to 7 weeks forms facial structures. If this migration and fusion is interrupted (usually by a combination of genetic and environmental factors), a cleft can develop along the lip.
