Question 1

is obesity a dominant or recessive trait?

Accepted Answer

Explanation : Neither. Obesity do not  have even cleat trait. Too many factors play roles: lifestyle and diet, physical activity are the most important.

Question 2

is cystic fibrosis a dominant or recessive trait?

Accepted Answer

Recessive: One needs two defective copies of the cystic fibrosis to develop the disease.

Question 3

is gestational diabetes a dominant or recessive trait?

Accepted Answer

Complex disease: Gestational diabetes (gdm), like type 2 diabetes, are related metabolic conditions with strong inherited genetic tendencies --- but multiple genes are involved in their expression (appearance in any person). So gdm is neither a dominant nor recessive trait. Whether a person gets gdm is also strongly impacted by age, weight, exercise levels, dietary factors, which are not genetically determined.

Question 4

my grandmother and my mother both have tested positive for celiac disease. is this a dominant or recessive trait?

Accepted Answer

Neither: While you may inherit the immune risk factor from a parent  that does not guarantee getting Celiac disease. If you have a 1st degree relative with confirmed Celiac disease then there is roughly a 20% chance of developing it in your lifetime.

Question 5

what do you suggest if my grandmother and my mother both have tested positive for celiac disease. is it a dominant or recessive trait?

Accepted Answer

Genetic: you may carry the gene for celiac- It is not a dominant or recessive gene. It is a gene that is associate to a chromosome that has been identified. In order to get the condition, you need to have the gene and an environmental trigger. You can be tested to see if you have the gene. The DR8 gene profile is seen in a large part of the population and may explain why celiac is being seen often.

Question 6

what is the difference between an autosomal dominant and autosomal recessive trait?

Accepted Answer

Input required: In dominant disorders, the dominant member of the gene pair controls how the gene activities are expressed, so the other gene can carry the same or normal information.In recessive disorders, the normal gene compensates for the bad information in the other gene, allowing a person to function normally unless both genes carry the bad information.

Question 7

is marfan syndrome a dominant or recessive gene?

Accepted Answer

Dominant: Marfan syndrome is transmitted in autosomal dominant fashion.

Question 8

is the bcra gene a dominant or recessive gene. can it skip a generation, or two?

Accepted Answer

See below: DNA repair genes, which BRCA 1 and 2 are, do not behave clearly as dominant or recessive, but for practical purposes you could consider these dominant. Not all women with the gene get cancer so it could skip a generation. See this site for more info.

Question 9

sickle trait is a recessive gene?

Accepted Answer

basically yes: The mutation that causes sickle cell disease is a recessive mutation in that you need two copies of the changed gene to have the disease (or one copy plus another mutation on the other gene like beta thalassemia, hemoglobin c, hemoglobin e, etc). If you only have one copy, you have sickle cell trait.

Question 10

is congenital ptosis of the eyelid a dominate trait or is it a recessive trait?

Accepted Answer

Dominant trait: Blepharoptosis can be familial, transmitted as a dominant trait.
