What else can I help you with?
Smooth coat is dominant to wire coat in terriers. You have a smooth coated terrier. How can you determine if your terrier is a carrier for wire coat or is homozygous for smooth coat?
You would have to breed it to a wire coat ( W_ x ww ) and if there are any puppies born with a wire coat then you know that your smooth coat carries the recessive gene.
If a dominant homozygous reproduced with a heterozygous could their offspring be recessive?
Let's see what combinations can be formed.HH, HH, Hh, Hh.So, yes their offspring can contain the recessive allele.(THe offspring can be a carrier of the recessive allele.)However, since it is impossible for the offspring to be homozygous recessive,the recessive trait/gene will not show in the offspring's phenotype.Hope that helps!
How do you prove if something is heterozygous?
The carrier must be Homozygous because if he were hetero it must be Hh and the dominant gene is expressed but homozygous gives them the possibility of hh (only a carrier) or HH (definitely a carrier) Don't totally understand the previous answer; however, I understand the question to mean that you want to know if you are homozygous or heterozygous for a certain trait. If you express a recessive phenotype, that is you have blue eyes for example, you are definitely homozygous for that trait. If one of your parents has a recessive trait, like blue eyes, and the other parent expresses a dominant trait, like brown eyes, AND if you have brown eyes, you can be sure that you are heterozygous. Otherwise it is impossible to tell until you have children. Then you can work backwards from you and your spouse, look at their parents and your parents and then figure the only possible way all those conditions could exist is if you are heterozygous or if you are homozygous for that trait.
What is a person with one recessive allele and one dominant allell for a trait called?
Heterozygous.
Another plant is said to be heterozygous for flower color what does this mean?
homozygous means that the alleles that make up the genotype are the same, for example homozygous dominant would have two dominant alleles (RR) or homozygous recessive would have two recessive alleles (rr). the alternative would be heterozygous, where the genotype contains both a dominant and a recessive allele (Rr). so a homozygous plant would either have two dominant alleles or two recessive alleles for the seed colour. Now the way to find out whether it is homozygous dominant or homozygous recessive is to do a cross with a homozygous recessive plant and look at the seed colour (the phenotype). if the the original genotype is homozygous dominant the offspring seed colour will show the dominant seed colour becasue it will be heterozygous. But if the original plant is homozygous recessive the offspring will show the recessive phenotype.
In biology an individual who has one copy of a recessive autosomal allele that causes disease in the homozygous condition?
carrier
A male who has normal vision marries a female who is a carrier for colorblindness can they have a colorblind daughter?
Assuming that the man who has normal vision is homozygous for normal vision, the couple's daughter will either be homozygous for normal vision or heterozygous (normal vision but carrier for color blindness) for normal vision. In light of this, the couple's daughter will not be color blind.
What is a person who has one recessive allele for a trait and one dominant allele for the same trait and is able to pass in the trait on to their offspring?
That is heterozygous. Some scientist call these "hybrids"(no joke)The person is heterozygous for that trait and will have the dominant phenotype.An organism with both a dominant and recessive allele for a specific trait is called an heterozygote. They are heterozygous for this trait.
What is a carrier in?
Genetically, a carrier is someone who is carrying a defective allele but doesn't display any of it's characteristics. For example: If a male (with chromosomes X and Y) has a dud X chromosome, he will undoubtedly show the characteristic that come with it. However, if a female (with chromosomes X and X) has the defective X chromosome, the symptoms will not be displayed due to the other, intact X chromosome. (assuming that the characteristic is recessive and not dominant) The female is a Carrier A carrier refers to someone who has a recessive gene that is not expressed (heterozygous). Such a trait is only expressed when an individual has two recessive genes (homozygous recessive). In humans, the gene for albinism is recessive. Any of us with normal pigmentation may be carriers for this trait. Parents who are both carriers will have a 1 in 4 chance of havibg an albino child. Genes (alleles) do not have to be "defective " to illustrate carriers. People with hitch-hiker's thumb are homozygous recessive. People with straight thumbs may be carriers (heterozygous) or have two dominant genes. "Carrier" can also refer to a molecule which transfers an ion or functional group to another molecule, e.g. NADP is a hydrogen ion carrier, Coenzyme A is an acetate carrier.

Is a person who is homozygous recessive for a recessive genetic diseases a carrier?
No, because he or she cannot pass the gene on to his or her offspring (because he or she does not have a copy of the gene).

No, because he or she cannot pass the gene on to his or her offspring (because he or she does not have a copy of the gene).
