What is the difference between a gene allele Chromosome and trait?
Wiki User
∙ 7y ago
Alleles are alternate versions of genes that code for certain phenotypes, or traits.
The traits of an individual are a result of the interaction between their genotype (alleles) and the environment.

What unusual result suggested that the eye-color trait is located on the X chromosome?
The correlation between the trait of the white eye color and the male sex of the affected F2 flies; there were no corresponding allele present on the Y chromosome.
Does sickle cell disease require two allele or multiple alleles?
Sickle cell disease is an autosomal reccessive sexlinked trait so, a female msut have 2 recessive alleles to have the trait and a male needs only one allele (this is because there is no corresponding site for this allele on the Y chromosome. The female can be a carrier of the disorder with the defective allele on one X chromosome and a normal allele on the other X chromosome. Female carrriers can have a mixture of normal and abnormal redblood cells.
What genotype must the person have who possessed the recessive phenotypes?
The genotype is homozygous recessive or the recessive trait is on the X chromosome and has no corresponding allele on the Y chromosome.
Why does a sex-linked trait only require one recessive allele on the X chromosome of a male to show the phenotype?
because the male only inherits one X chromosome (from his mother), his other sex chromosome is Y (from his father)
An allele that is dominated or cover up by another allele is called what?
It should be a dominant allele--a dominant allele's trait will be expressed over the recessive allele's trait.
Which trait will a male exhibit if he carries a recessive allele on the X chromosome?
A male carrying a recessive allele on the X chromosome will exhibit the recessive trait. This is because the Y chromosome generally does not have matching genes for the X chromosome, unlike the other 22 pairs if chromosomes in the nucleus.
What unusual result suggested that the eye-color trait is located on the X chromosome?
The correlation between the trait of the white eye color and the male sex of the affected F2 flies; there were no corresponding allele present on the Y chromosome.
What is the difference between the dominant and recessive allele for a trait?
An individual must have 2 recessive alleles in order for a trait to show up. One must only have 1 dominant allele in order for a trait to occur.
Snice the allele for colorblindness is located on the x chromosome which type of trait is colorblindness?
Sex linked

The genotype is homozygous recessive or the recessive trait is on the X chromosome and has no corresponding allele on the Y chromosome.
Sex linked traits are primarily found in?
Males, because they have one X chromosome, in which the traits are carried on. Therefore, if they have one allele they will have that trait because they do cannot have another allele to affect it.
What is difference between a dominant trait and a recessive trait?
A recessive trait is a trait that is not shown or expressed physically but is retained within the persons genes, whereas a dominant trait is a trait which opresses the recessive trait and is prodominantly shown or expressed physically. For example it is possible for two red-haired parents, both with recessive dark haired genes, to have a dark haired child. they must both have the recessive gene or the dominant gene of red - hair will be expressed in the child

because the male only inherits one X chromosome (from his mother), his other sex chromosome is Y (from his father)
What is member of a gene pair that determines a specific trait is?
an allele
Why can there only be only two forms of a gene in any cell?
Basically, because there are two sexes. One gene allele is on one chromosome from dad and the other allele is on the chromosome from mom. If more than two alleles for a trait, only two can be represented in the genome of the organism.
