What else can I help you with?
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 a terms dominant and resicieve mean?
In the context of genetics, "dominant" refers to an allele that expresses its trait even when only one copy is present, overshadowing the effect of a recessive allele. Conversely, a "recessive" allele requires two copies (one from each parent) to express its trait, as it is masked by the presence of a dominant allele. For example, in a trait governed by these alleles, if an individual has one dominant and one recessive allele, the dominant trait will be observed.
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.
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 allele masked by the dominant allele?
An allele that is masked by the dominant allele is called a recessive allele. When an individual has one dominant allele and one recessive allele, only the trait determined by the dominant allele will be expressed. The recessive allele will only be expressed if an individual has two copies of it (homozygous recessive).
Is albinism controlled by a dominant allele or by a recessive allele?
Recessive allele.
Does a recessive allele need another recessive allele to be expressed?
Yes, a recessive allele needs to be paired with another recessive allele in order to be expressed. This is because recessive alleles are only expressed when an individual has two copies of the recessive allele, one from each parent. If an individual has one dominant allele and one recessive allele for a particular trait, the dominant allele will be expressed.
What is the term for an allele that is not expressed in the phenotype of a heterozygous individual?
incomplete dominance source: PH Bio textbook
Is albinism controlled by a dominant allele o recessive allele?
It is controlled by a recessive allele.
What allele is covered up by the dominant allele?
An allele that's masked by a dominant gene is called a "Recessive"recessiverecessive traitThe recessive allele. Often depicted as the "small r" in examples: Rr, R=dominant, r= recessive.
An allele that is hidden by other alleles is called?
i think the answer your lokking for is recessive Recessive is when you have a trait in your genome but it doesn't show in your physical appearance
How is a recessive allele from a dominant allele?
its different because adominant allele is in charge
What is it Dominant allele What is a recessive allele?
A genotype in which there are both a dominant and a recessive allele is called heterozygous.
Why will a recessive allele not show up if?
A recessive allele will not show up if there is a dominant allele present.
In one allele is dominant to a recessive allele?
In a dominant-recessive allele relationship, the dominant allele will be expressed phenotypically over the recessive allele. This means that even if an organism carries one dominant and one recessive allele for a particular trait, the dominant allele will determine the observable characteristic.
What is e difference between a dominate and recessive allele?
The answer is that The difference is that dominant dominates, and recessive is dominated.
