WHAT IS THE PROBABLITY OF A HOMOZYGOUS RECESSIVE INDIVIDUAL (ss) producing a gamete with a dominat allele?
A homozygous recessive individual (ss) carries two copies of the recessive allele and does not possess a dominant allele. Therefore, when this individual produces gametes, all gametes will carry only the recessive allele (s). Consequently, the probability of a homozygous recessive individual producing a gamete with a dominant allele is 0%.
How is codominance same as having no dominat?
The genotype of the offspring affects the triple allels setup which causes the living organism it self to not be adaptable to recessive or dominant allels causing damage to the nucleus of each 69 pairs of chromosoms
How do you write genes to express dominat and recessive?
Dominant: upper case letterRecessive: lower case letterUsually the letter that is used is the first letter of the recessive trait, for instance since albinism is a recessive trait, someone who is an albino would have aa. Someone who is not would either be Aa or AA.In other examples you use a upper case letter and a superscript letter, usually the first letter of the name. For instance daltonism, which is recessive and linked to the X chromosome, would be XDXd for a female carrier, XdXd for a daltonic female and XdY for a daltonic male.For blood types, for type O, which is recessive, would be ii. Type A would be either IAi or IAIA. Type B would be either IBi or IBIB and type AB would be IAIB.
What is meant by dominat and ressesivegene give an exampleof each?
A dominant gene refers to a gene that is expressed over another gene in the same position on a chromosome. It will always show its trait in the individual's phenotype if it is present in their genotype. For example, if a person inherits a dominant gene for brown eyes, they will have brown eyes regardless of whether they also have a recessive gene for blue eyes. On the other hand, a recessive gene refers to a gene that is not expressed when there is a dominant gene present. It is only expressed in the phenotype when there are two copies of the recessive gene in the genotype. An example is the gene for blue eyes, which will only be expressed when an individual has two copies of the recessive gene and no dominant gene for brown eyes.
Is green a dominat trait?
Depends on what organism, "green" cannot simply be dominant or recessive, it needs to be put in context of some form or organism - for example: are green eyes dominant over blue eyes in humans, or is green foliage dominant over grey foliage in cacti.
Is angelman syndrome a recessive or a dominant?
It is recessive
Is albinism a dominat or reccesive trait?
Albinism is a recessive trait which will result in a lack of pigmentation in the skin eyes and hair. It occurs about 1 in every 17,000 people in the U.S.

What is it called when a ressesive and dominat gene mix?
When a recessive and dominant gene mix, the dominant gene will typically determine the trait expressed in the offspring. This is known as dominant inheritance, where the dominant gene masks the presence of the recessive gene in determining the phenotype.
Who identified Angelman syndrome?
in 1965 Harry Angelman
When was Harry Angelman born?
Harry Angelman was born in 1915.
When did Harry Angelman die?
Harry Angelman died on 1996-08-08.
Do black people have angelman syndrome?
Yes. All races and both males and females get Angelman Syndrome.
What percentage of babies is born with Angelman syndrome?
One out of 20,000 babbies are born with angelman syndrome.
What is Angelman's Syndrome's scientific name?
Angelman syndrome's scientific name is "AS," or "Angelman syndrome." It is a genetic disorder characterized by developmental delays, speech impairments, and unique behaviors. It is caused by a loss of function in a specific gene located on chromosome 15.
Is Angelman syndrome the same as Down syndrome?
Angelman syndrome is a genetic disorder, as is Down syndrome. But they are not the same. Angelman Syndrome involves a deletion of Chromosome 15, whereas people with Down syndrome have an extra copy of Chromosome 21.
What are the difference between dominant and recessive genes?
Dominant genes will cover up recessive genes. Take a simplified version of eye color for example. Brown is dominant and blue is recessive. Someone might have the allele for both brown and blue, but their eyes will be brown because of the dominent brown gene. If there are two parents that carry the recessive gene, neither will be blue eyed, but they will have a chance of having a blue eyed child if both pass on the recessive gene.
