What is an allele that produce a trait in the heterozygous condition is?
homozygous
An organism that has two identical alleles for a trait?
Are known as homozygous. Homozygous individuals can also be called 'purebred'. Organisms with two different alleles are known as heterozygous.
Condition where the pair of alleles for a characteristic are the same?
homozygous
A homozygous condition would be the possession of alleles for?
A homozygous condition would be the possession of alleles for red hair and red hair. A heterozygous condition would be characterized by the possession of alleles for brown hair and red hair.
What is the name of the condition when a person has inherited the genotype HH?
Homozygous dominant.
What are two possibilities for a specific trait?
Allele The specific trait may be either in homozygous or heterozygous condition. The expression of the trait depends on its dominant or recessive condition.
Two identical alleles for a particular gene is what?
I assume that you are looking for the term "homozygous," meaning the two alleles for any given gene are identical.http://en.wikipedia.org/wiki/Zygosity#Homozygous
When two alleles of a pair are identical it is a condition if the two alleles are different this is a condition?
When identical: homozygous. when different: heterozygous.
What refers to the genotypic condition that must be present for a recessive to be visible?
Homozygous. ( generally )
When will homozygous gene be expressed?
A cell can be described as being homozygous for a particular gene when there are identical genes on a pair of chromosomes (humans have 23 pairs). Under these conditions, we would see the expression of the gene under the homozygous condition. If the cell had a heterozygous condition, then there would not be identical genes found in the chromosome pair.
Condition that exists when the heterozygous phenotype is somewhere in between the two homozygous phenotypes?
Incomplete dominance
In biology an individual who has one copy of a recessive autosomal allele that causes disease in the homozygous condition?
carrier
