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.
The most powerful genes are said to be?
Dominant, as in dominant and recessive (weaker) genes.
What does it mean to be homozygous dominant heterozygous or homozygous recessive?
Homozygous means "same" so a homozygous recessive trait would be a same [with parents] trait that is not the stronger trait which is dominant. Dominant is stronger showing trait, recessive is weaker trait. If you are dealing with Punnett squares then tt is homozygous recessive and TT is homozygous dominant. Hope this helped...
Do action potentials become weaker with distance?
action potentials are non-decremental and do not get weaker with distance.
Can your thigh muscles get weaker?
If you cease to use them for a while, yes, they will get weaker.
What is the difference between dominant alleles and recessive alleles?
dominant-appears in first generation recessive-seems to dissapear
What is the relation between dominant and recessive alleles?
the dominant trait is the stronger one and the recessive trait is the weaker one
What is a recessive genes?
Recessive is a relative term used to describe the relationship to another allele termed the dominant allele. That traits of the recessive allele will only be shown if the person has two copies of the recessive allele. If a dominant allele is present, then the recessive trait will not be shown.
13 What is the name of a weak trait that is masked by a stronger trait?
The weaker trait is called the recessive trait The stronger one is called the dominant trait
What is the weaker allele in a pair of genes?
Recessive Allele

Are dominant traits more likely to be inheritd then recessive traits?
Yes. When looking at Gregor Mendel's laws of inheritance, the Dominant allele will always be inherited by the offspring, as it is more potent than the 'weaker' recessive allele (unless the recessive allele is present in both parents; this can be in the form of Aa or aa, but it must be present in both for the recessive allele to be present in the offspring). There are other cases, though, such as co-dominance, in which recessive alleles are more likely to be present in the offspring, but speaking in general terms, it is the Dominant (ex. AA / Aa) alleles that show up more commonly in offspring than the recessive (ex. aa) alleles.
If a dog is bred with its sibling does the puppy have a weaker bone structure?
The puppies will have problems because of this inbreeding. One of these can be weaker bone structure. They have these problems because genetic problems that are usually masked by dominant genes are uncovered by two recessive genes that both siblings received from their parents.
The most powerful genes are said to be?
Dominant, as in dominant and recessive (weaker) genes.
What are dominant and recessive alleles?
a dominant allele is an allele that takes over the recessive allele and a recessive allele is a trait that is skipped or held backDominant: Tongue Roller Free (Unattached) Earlobes Farsightedness Astigmatism Freckles Dimples in cheeks Feet with normal arches PTC taster Widow's Peak Double-jointed thumb Broad lips Polydactyly (Extra fingers and toes) Syndactyly (Webbed digits) Achondroplasia (herterozygous: dwarfism; homozyogous: lethal) Huntington's disease Normal skin pigmentation Absence of Tay-Sachs disease Normal Mentation Recessive: Inability to rill tongue into U shape Attaches earlobes Normal vision Absence of freckles Absence of dimples Flat feet PTC nontaster Straight hairline Tight thumb ligaments Thin lips Normal number of fingers and toes Normal digits Normal carilage bone formation Absence of huntington's disease Albinism Tay-Sachs disease Cystic Fibrosis Schizophrenia (Courtesy of "Human Anatomy and Physiology)
The weaker of two genes is called what?
dominant
Is long hair in dogs a dominant trait?
Genetics is incredibly complicated microbiology, and this is an extremely oversimplified introduction to very basic genetic concepts. Please keep that in mind as you read through this page. Many people have dedicated their entire careers to the study of genetics, and much is being learned on a daily basis in the continuing field of genetic research.Genes, the unit of heredity in cells, are inherited from one's parents. They are made up of pairs of alleles in the individual. One gene allele is inherited from the mother (via the egg), and the other one from the father (via the sperm).Capital letters usually indicate a dominant gene allele, or one that is "stronger". Only one dominant allele of a gene pair needs to be present for that allele to be expressed (be evident). Dominant alleles mask, or hide, the recessive ("weaker") allele. The recessive allele must be inherited from both parents in order to be expressed. In other words they must be present as a pair to be shown. Recessives are indicated with a lower case letter.Most visible traits are produced by many genes interacting in the individual. These are called polygenic traits. But some traits are controlled by a single gene. For our theoretical simplified example, we will use a single gene trait.A = dominant allele a = recessive alleleIf A indicates short hair in a dog, for this example, and a indicates longhair, then:AA would be a shorthaired dog with no longhair recessive.Aa would be a shorthaired dog with a longhaired recessive, but you would not know it was carrying the longhaired trait by looking at the dog, since the dominant allele, A, masked the recessive allele, a.aa would be a longhaired dog , since the recessive alleles must be present in a pair to be expressed, however please see * Note below regarding the quantity of hair likely to be present in such a dog that had an Aa parent. As can clearly be seen, it is not possible for the aa dog to carry or pass on the dominant trait, which for this example, is shorthair..Forget all that ! I have been breeding dogs for over 55 years and i can tell you that the long coated dog is a dominate. If you breed 100 years of short coats and you breed one long coat into your short coat, you will get short coats, but if you choose the long coat pup and breed back to your long coat you will get a majority of long coats. Then you breed all long coats for 100 years and bred to a short coat you will retrace your steps in reverse. Once you have long coats you will never ever get a short coat unless you 'outcross' to a short coated breed. example is the American Cocker spaniel which can never go back to its former look. The judges and breeders chose to go with the long coat and now, you will never be able to get what the standards call for. All American Cockers should be thrown out of the show rings for non conformation to the standards of their breed. your answer is YES
