Is apert syndrome dominant or recessive?
Recessive, but dominant in some rare cases.
What is the genotype of a child if the mother is homozygous for the dominant trait and the father is homozygous for the recessive trait?
The dominant parent is most likely homozygous dominant, and the recessive parent has only the homozygous genotype. So the dominant parent can pass on only dominant alleles for this trait, and the recessive parent can pass on only recessive alleles for this trait. So all of the offspring would be heterozygous and have the dominant phenotype.
If about 50 percent of the offspring have the dominant phenotype and 50 percent have the recessive phenotype what are the genotype of the parents?
If the phenotype is recessive then the genotype must be dd.
If one parent has two dominant alleles and another parent has two recessive alleles the offspring will have?

What is recessive and dominant mean?
I am pretty sure the recessive and dominant alleles you are talking about are covered in Biology. Recessive alleles are basically alleles that are received from both parent's DNA that are carries, (dd). However, dominant alleles are (exactly what it says) always expressed. If there is one dominant allele and one recessive allele the dominant allele overpowers the recessive. (DD) and (Dd)overpowers (dd).
Is Marfan syndrome contagious?
Marfan's syndrome is not contagious. A person can only get it by inheriting it from a parent.
Is apert syndrome dominant or recessive?
Recessive, but dominant in some rare cases.
How does a person inherit marfan syndrome?
Marfan syndrome is an inherited disorder that is typically passed down from one generation to the next through an autosomal dominant pattern of inheritance. This means that if one parent carries the Marfan syndrome gene, there is a 50% chance that they will pass it on to each of their children. In some cases, Marfan syndrome may also occur as a result of a spontaneous genetic mutation.

Is Edward's syndrome caused by a recessive gene?
Edward's syndrome is not technically recessive or dominant, because it is not caused by a single gene. Rather it happens due to a trisomy of chromosome 18 (or just of a part of said chromosome). Parent's may be healthy and still have offspring with the syndrome not because its recessive, but because the trisomy arises during meiosis of the gametes. Whatever happens to the gametes affects only the offspring not the carrier parent.
Do you get your eye color from your parent?
Yes you get your eye color from your parent. The parent that carries one dominant gene and one recessive gene for a specific eye color and the other parent carries two recessive genes for a different eye color, you will get the eye color of the parent who carries the dominant and recessive gene. In other words, the dominant gene trumps the recessive gene. In another scenario, if both parents carry two recessive genes for a specific eye color, then you will inherit the recessive gene of that color.
Is Marfan Syndrome common in a specific race?
About 1 in 5,000 people have Marfan syndrome, including men and women of all races and ethnic groups. About 3 out of 4 people with Marfan syndrome inherit it, meaning they get the genetic mutation from a parent who has it. But some people with Marfan syndrome are the first in their family to have it; when this happens it is called a spontaneous mutation. There is a 50 percent chance that a person with Marfan syndrome will pass along the genetic mutation each time they have a child.
What are causes of Marfan syndrome?
It is a genetic disorder and if one parent has it, there is a 50?50 chance that the child will have it.
Is turner syndrome a dominant or recessive?
yes it is a recessive trait
A dominant trait of marfan syndrome?
35 different signs are seen in Marfan syndrome. Most are visible signs associated with the skeletal system. Many grow to above-average height with having long, slender limbs with long fingers and toes. The most deaths involve the cardiovascular system. This gene is dominant. If one parent has it, there is a 50/50 chance that an offspring will have it. Abraham Lincoln was once thought to have had this, but no longer.
Where can one find information on marfan?
One can find information on marfan on its official website. Marfan syndrome is a disorder that affects connective tissue. It is usually passed from parent to child through genes.
