∙ 15y agoI will try to answer what I think this question is trying to ask. the alleles are alternatives form of a gene. Genes are the components of the chromosomes. In other words the chromosomes are packages of genes. Genes are sections were information of an especific part of our body. ex gene for black hair, for dark skin white skin, color of eyes ect.

What an allele?
An allele is an alternative form of a gene that is found at the same location on a chromosome.
Is a chromosome a allele?
No. An allele is the tip of a chromosome.
Is homologous recombination a type of mutation?
No. A mutation can change an allele into any other allele. Homologous recombination can only change an allele to the allele of the homologous chromosome.
How is a chromosome effeced by achondroplasia?
The only difference in the chromosome is the presence of the allele that results in an individual with acondroplastic dwarfism. The chromosome affects the structure of the organism, the allele affects the growth plates of the long bones resulting shortened limbs.
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.

No. An allele is the tip of a chromosome.
A locus the location of an allele on a chromosome?
It defines location of a gene on a chromosome. Also, it means a genetic susceptibility factor. It is usually a part of a chromosome when disease is analyzed and broke down. Cancer or heart disease.
What is dominant the X or the Y?
An allele on either X or Y could be dominant over the allele on the other chromosome, but it is more common for the allele on the X to be dominant, because the Y chromosome is much smaller than the X and contains fewer genes. In many cases, there is no allele for a particular gene on the Y chromosome; so whatever allele is on the Y will be dominant.
Is homologous recombination a type of mutation?
No. A mutation can change an allele into any other allele. Homologous recombination can only change an allele to the allele of the homologous chromosome.

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 allele combination would will have a colorblind child?
carried on the x chromosome

What are pairs called?
A gene pair is called an allele. An allele is an alternative form of a gene that is located on a specific chromosome at a specific place.
What is the probability that a particular allele will be in a gamete?
chromosome segregationIf the character is governed by a single allele and it is dominant, than its probability to be in the gamete is 75%.
A gene on the female chromosome having no allelic partner on the y chromosome would be what?
An individual (male) with an allele on the X chromosome but no corresponding allele on the Y chromosome is described as hemizygous. Genes which are inherited in this way are described as sex-linked or X-linked. An example is hemophilia - the inability of the blood to clot. It is caused by a recessive allele, so males only need to inherit one copy to develop the characteristic. Females can inherit one hemophilia allele and one normal allele, so they can act as carriers of the disease without developing it themselves. See http://en.wikipedia.org/wiki/X-linked_gene
