In humans the alleles for hemophilia h is recessive. Which phenotype is displayed in an individual with the genotype XhY?

Genes that come together with different alleles are called _____.


If two dominant alleles are expressed at the same time this is a case of what?

This is called codominance. In codominance, both alleles are fully expressed in the phenotype of the individual.


When both alleles are expressed in an offspring this is called?

codominance. In codominance, both alleles contribute to the phenotype and are fully expressed in the offspring. This results in a distinct phenotype that is a combination of the traits associated with each allele.


What is it called when one trait is completely dominant over another?

This is called codominance in this case, neither allele is dominant over another, it creates in heterozyogous individuals a phenotype that is not in intermediate, nor the phenotype either of the two alleles create, but rather, a different phenotype.


Using the terms dominant recessive explain the difference between genotype and phenotype?

No, I think you have your terms confused.The terms "dominant" and "recessive" are applied to alleles of a genotype. A genotype is an expression (using upper- and lower-case letters) that shows what alleles an organism has for a particular locus. The two alleles (in most cases) inherited (one from mother and one from father) can either be dominant or recessive. The recessive allele is not fully expressed in the presence of the dominant allele and is only expressed when there are two recessive alleles. The genotype could be called "recessive" I suppose if the genotype is homozygous recessive. But remember that two recessive alleles as a genotype is only one possibility - in which case you can't say the "genotype is recessive".The phenotype is dependent on the genotype. If present, the dominant alleles (in simple Mendelian genetics) will determine the phenotype - what the organism's trait or characteristic is. The phenotype will never be what is coded by the recessive allele unless the genotype is two recessive alleles.

What is an interaction between alleles in which both alleles are expressed more or less equally or a blending occurs called?

Those would be called co-dominant alleles.


What phenotype produces is between the two homologous parents?

The phenotype that is a combination of traits from both homologous parents is called the composite phenotype. It results from the interaction of different alleles inherited from each parent. This can lead to a unique expression of characteristics not seen in either parent.


What are alleles that have an effect on an organisms phenotype?

Alleles that have an effect on an organism's phenotype are called dominant alleles. Dominant alleles mask the effects of recessive alleles in heterozygous individuals, resulting in the dominant allele's phenotype being expressed.


Why is a dominant alleles called a dominant?

because it dominates the phenotype

What is it called when the presence of two different alleles result in an intermediate phenotype?

It is called codominance or incomplete dominance.


In humans the alleles for hemophilia h is recessive. Which phenotype is displayed in an individual with the genotype XhY?

Genes that come together with different alleles are called _____.


What are inactive alleles?

Inactive alleles are versions of a gene that do not produce a functional protein or have reduced activity due to mutations. These alleles may not contribute to the individual's phenotype or may have a diminished effect compared to active alleles. Inactive alleles can result in genetic disorders or variations in traits.


The detectable traits of an organism as determined by what alleles are present is the what?

The detectable traits of an organism as determined by what alleles are present is the phenotype. Phenotype is the observable characteristics of an organism, such as its physical appearance or behavior, which are influenced by both genetic and environmental factors.


If both alleles are equally expressed in a heterozygote the relationship is called?

The expression of more than one allele is referred to as incomplete dominance. For example a flower that is heterozygous red and white will have a pink phenotype.
