What is the probability that each child born to two carriers of a recessive disorder allele will have the disorder?

The child will have the disorder, only if the recessive allele from both the parents is transferred to the child. Therefore, the probability is 1/4.

What is a recessive allele?
Recessive allele is a trait that doesn't show in one's phenotype (observable trait) if there is a dominant allelle present. Only when you inherit a recessive allele from both parents (aa for example and not Aa) does the trait show in your phenotype.
What is the probability that a particular allele will be in a gamete?
chromosome segregationIf the character is governed by a single allele and it is dominant, than its probability to be in the gamete is 75%.
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!
What is the percentage of offspring that will exhibit the dominant trait from A crossing of A homozygous dominant and homozygous recessive individual?
The homozygous dominant individual can only pass on the dominant allele and the homozygous recessive individual can only pass on the recessive allele, therefore all offspring will be heterozygous and have the dominant phenotype.
When trait is called recessive?
recessive is when you have another allele that supress the recessive one, you have to thing how this could be done in a methabolic pathway, and you will see that exist many ways for an allele be dominant and the other recessive (you just can say dominant and recessive if you are talking at alleles ,this is genes at the same locus. my mother language is no inglish maybe i have comit many gramatical errors but what i am saying is correc i am student of biotechnology.
Why were heterozygous individuals called carriers for non-sex-linked and x-linked recessive patterns of inheritance?
I don't know and don't care
What is the name of the gene pair that consist of a dominant allele and recessive allele?
The name of the gene pair that consists of a dominant and recessive allele, i.e. (Xx) will be a heterozygous allele. In this situation, the characteristics of the dominant characteristic will mask that of the recessive allele. People have have a heterozygous genotype may be carriers for diseases that reside on the recessive allele.
What does recessive disorder mean?
Recessive allele disorders are just as they sound - they are disorders that are a result of a prevalent recessive allele in one's genetic makeup. A recessive allele disorder will rarely occur since it is dependent on the crossing of two heterozygous parent cells, but it can lead to interesting consequences. An example of a recessive allele disorder is hemophilia - the body's inability to clot blood - and it has affected much of the European royalty in history, such as Queen Victoria of Great Britain.

In humans heterozygotes are referred to as particularly when the recessive allele is associated with a genetic disease?
carriers
What is the probability that a offspring will have wrinkled seeds?
R represents the dominant round allele, and rrepresents the recessive wrinkled allele. :D

What is allele masked by the dominant allele?
The Allele That Is Covered By The Dominant Allele Is The Recessive Allele.
Is it true that people who are heterozygous recessive allele but who have a normal phenotype eill not pass the harmful recessive allele to their kids?
It depends on the genotype of the childs other parent. If your partner is heterozygous as well then there is a 25% chance your child will be homozygous recessive. If they are homozygous dominant then none of your children will have the phenotype of the recessive trait. They will just possibly be carriers of the recessive allele.
What is a sex linked disorder caused by a recessive allele on the x chromosomes?
colour blindness
What is the probability that certain genotypes and phenotypes will occur?
This depends entirely on the genotype of the parents. The probability of getting a specific genotype is the probability of getting the correct allele from mother (1/2) multiplied by the probability of getting the correct allele from father (1/2) multiplied by the number of ways this can occur. The probability of getting a phenotype, if the phenotype is dominant, is the sum of the probability of getting two dominant alleles, and the probability of getting one dominant allele. If the phenotype is recessive, the probability is equal to the probability of getting two recessive alleles.
Is albinism controlled by a dominant allele or by a recessive allele?
Recessive allele.
