When two different alleles occur in a cell?

A heterozygous condition.


Why would defective recessive alleles be retained in the gene pool?

Defective recessive alleles can be retained in the gene pool because they may not affect individuals who are carriers of the allele (heterozygotes). Additionally, in small populations, genetic drift can lead to the retention of defective alleles. Finally, if the defective allele provides a selective advantage in certain environmental conditions, it may persist in the population.


Hurlington disease is an autosomal dominant disorder that affects the nervous system if a man is heterozygous for the alleles that cause the condition and has children with a woman who lacks then?

If a man who is heterozygous for the Hurlington disease alleles has children with a woman who does not have the alleles, there is a 50% chance that each of their children will inherit the disease allele. Since Hurlington disease is autosomal dominant, inheriting just one copy of the disease allele will result in the individual being affected by the disorder.


What term is used when both alleles are different?

The condition called in a case when you have a two different types of alleles is called as Heterozygous and when this is exactly the opposite that is when it has the alleles for the same source we describe such a condition as a Homozygous. This two terms are of most importance when you take the genetics


Organism that has two diffrent alleles for a single trait?

An organism that has two different alleles for a single trait is called heterozygous. This means that the organism inherited different versions of the gene responsible for that trait from each parent.

The heterozygous condition.


When two alleles of a pair are identical it is a condition if the two alleles are different this is a condition?

When two alleles of a pair are identical, it is referred to as homozygous. When the two alleles are different, it is referred to as heterozygous. Homozygous individuals have two identical alleles (e.g., AA or aa), while heterozygous individuals have two different alleles (e.g., Aa).

An allele that is not expressed in the heterozygous condition is?

If it's not a heterozygous, the alleles would either be two capital letters (TT) or two lowercase letters (tt). This is because the organism has either both two dominant alleles or two recessive alleles.
