How do you know if the recessive gene will be the recessive in the offspring?
If the recessive gene is present in both of the parents.
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!
A recessive lethal gene exists in a population and remains for several generations Which woman could have passed the recessive lethal allele to offspring but not have the disease herself?
a woman who is heterozygous for the gene
If a genetic disorder is carried on a recessive gene which if any will have the disorder?
If a genetic disorder is carried on a recessive gene, offspring will only have the disorder if both parents have the recessive gene.
Is a disorder know as a dominant or recessive?
Dominant disorders can be passed onto the offspring if the dominant gene is present in the offspring.
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).
. Is a person who is homozygous recessive for a recessive genetic disease 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).
How do you find possible phenotypes of offspring?
Mendel Diagrams. If the offspring gets a dominate gene from both parents, the offspring will exhibit traits from the dominate gene. If the offspring gets a dominate gene from one parent and a recessive gene from another, the offspring will exhibit traits from the dominate gene. If the offspring get a recessive gene from both parents, the offspring will exhibit traits from the recessive gene.
The probability of a homozygous recessive offspring resulting from a cross between two homozygous dominant individual is?
It depends on the parents. The parent could have two dominant genes which would give a 0% chance of the offspring being recessive. The only way that the offspring could have a recessive characteristic is if the both parents have one dominant and one recessive gene, a 25% chance. The chance that both parents would pass on the recessive gene (if they have one dominant and recessive gene) is also 25%, because there is a 50% chance for each parent.
Is a person who is homozygous recessive for a recessive genetic disese a carrier?
As long as a persons genotype consists of at least one recessive gene, they can pass it on to offspring to give them the disease, which makes them a carrier. Since this persons genes are both recessive, it is definite that they will pass on the recessive gene.
Is inherited from only one parent the offspring Will have that genetic?
Recessive gene
When is a recessive allel expressed in offspring?
A recessive phenotype is expressed in an offspring that has a homozygous recessive genotype for that trait.
