Is it possible for someone to have a trait in their genotype but not have it show up in their phenotype?
You might be surprised to learn that, for some traits, the phenotype might not occur as often as the genotype. For example, say everyone in population W carries the same allele combinations for a certain trait, yet only 85% of the population actually shows the phenotype expected from those allele combinations.
What is a person who has the gene for a particular trait but doesn’t show that trait?
A hereditary carrier (genetic carrier or just carrier), is a person or other organism that has inherited a recessive allele for a genetic trait or mutation but usually does not display that trait or show symptoms of the disease.
Why are you unable to determine your genotype for a dominant trait that you possess?
Bottom line is you can’t always figure out genotype from phenotype with a dominant trait because dominant traits can happen with two different genotypes.
Which word describes having one of the same allele of a particular gene?
Homozygous = Homozygous is a genetic condition where an individual inherits the same alleles for a particular gene from both parents.
What is an allele that expresses itself and inhibits the expression of others?
According to Mendles law of inheritance, the dominant factor can express itself completely and suppresses the other’s traits. The heterozygous condition carries both dominant and recessive alleles, the presence of dominant allele masks the expression of the recessive allele.
When the genotype consists of a dominant and a recessive allele?
An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. In our example, this genotype is written Bb. Finally, the genotype of an organism with two recessive alleles is called homozygous recessive.
When an allele determines the appearance of an organism?
Alleles contribute to the organism’s phenotype, which is the outward appearance of the organism. Some alleles are dominant or recessive. When an organism is heterozygous at a specific locus and carries one dominant and one recessive allele, the organism will express the dominant phenotype.
