What is the condition called when there are many genes that affect a trait which are susceptible to changes due to the environmental factors?
This condition is known as polygenic inheritance. It involves multiple genes contributing to a trait, and the expression of these genes can be influenced by environmental factors. The combination of genetic and environmental influences leads to a wide range of variation in the trait.
Is cleft lip sex linked trait?
No. There are several genes that can result in clefting with varying degrees of severity. And there are effects from chemicals that can increase the severity.
What is multifactorial polygenic threshold theory?
Multifactorial polygenic threshold theory proposes that complex traits are influenced by both genetic and environmental factors. It suggests that multiple genes contribute to the expression of a trait, and a certain threshold of genetic and environmental factors must be reached to manifest the phenotype. This theory is often used to explain the inheritance of complex traits such as height, intelligence, and susceptibility to diseases.
Is sickle cell anemia dominant recessive x-linked recessive a chromosomal error or a multi-factorial trait?
Sickle cell anemia is a recessive genetic disorder caused by a mutation in the HBB gene, located on chromosome 11. It is inherited in an autosomal recessive pattern, meaning a person needs to inherit two abnormal copies of the gene (one from each parent) to have the disease. It is not an X-linked disorder or a multifactoial trait.
Where to find a Punnet Square for Edwards Syndrome?
A Punnett square is a tool used in genetics to predict the outcome of a particular cross or breeding experiment. In the case of Edwards syndrome, a Punnett square would not be applicable as it is caused by a random error in cell division and not by a specific genetic trait passed down from parents. It is a chromosomal disorder caused by the presence of an extra chromosome 18.
Is alzheimer's an autosomal dominant trait an autosomal recessive trait an X linked recessive trait or a chromosomal error?
Alzaymrs is ottosomal dominent
What is a multifactorial trait?
Trait that is controlled by many genes and is also influenced by the environment.
What is the condition called when there are many genes that affect a trait which are susceptible to changes due to environmental factors?
Multifactorial trait
How many people have a cleft chin?
About 5-10% of the global population is estimated to have a cleft chin, also known as a "dimple" or "chin cleft." It is a genetic trait caused by a dominant gene.
Is cleft chin a dominant trait?
Both, depending on the genes of the parents. It can also be on genetic and caused by the child's environment in the womb and in very few cases the child's tongue blocks the palate from fully closing

Of the combination Cc and cc what is the ratio of offspring with a cleft chin to offspring without a cleft chin?
The combination Cc has a 50% chance of having a cleft chin trait, while the combination cc will always result in offspring without a cleft chin. Therefore, the ratio of offspring with a cleft chin to offspring without a cleft chin from the cross Cc and cc is 1:1.
What if both parents have cleft chins and both are homozygous how many children in a family of four will have cleft chins?
All four children in the family will have cleft chins. This is because the parents are homozygous, meaning they have two copies of the gene for cleft chin, and will pass on one copy to each of their children, resulting in all of them inheriting the trait.
How can you get a cleft chin?
One can be born with a cleft chin. Another way one would get a cleft chin, if they wanted it, would be through plastic surgery. A cleft would be bored into the fissure of the chin bone and then one would have a cleft chin.

No. There are several genes that can result in clefting with varying degrees of severity. And there are effects from chemicals that can increase the severity.

Is there a relationship between the frequency of a trait in a population and whether that trait is dominant or recessive?
Some observable traits in humans are dimples, earlobes, tongue-rolling, cleft chin, hairline, and freckles. The relationship between the frequency of a trait in a population and whether the trait is dominant or recessive because in inherited human traits, the offspring can either have dimples or no dimples.
