Are alleles made up of DNA?
All alleles contain DNA. They are the genes. An allele is one form of a gene. For example, the gene for flower color in pea plants has two alleles, one for purple flower color, and one for white flower color.
What does the term independent assortment of alleles mean when used in the context of genetics?
It is basically a long process of your strands of DNA combining together after a long period of time.
When performing a DNA test to establish maternity do all the alleles have to match?
No, because some of the alleles will match the father; however, all of the alleles must either match one of the mother's alleles or one of the father's alleles.
How can DNA tell if 2 humans are brother and sister?
A basic DNA kinship test can be done, which compares two people on a small set of autosomal genetic markers, called alleles. An allele is a form of a DNA sequence of a particular gene. A person inherits alleles randomly from both parents. Basically, by testing to see how many alleles two people share in common, a conclusion of high or low probablity of relatedness can be drawn. Some values are more common to match with people, while others are not. The rarer the alleles that match up, the more likely a person is related to the comparison. Therefore, if you share a lot of rare alleles with a person, there is a high probability you two are related.
What is the DNA sequence that affects genetic information?
The alleles : Dominant and recessive i think
Is mapping the process that DNA to form new alleles?
no, you must first create a DNA model like a twisted ladder then you find your pattern that was created to form the new alleles.
One of a number of different forms of a gene?
In the form of DNA
Is recessive the process in which DNA changes to form new alleles?
No, recessive traits refer to the inheritance pattern of the allele. In the simple case where a trait is either expressed or not, if it is a recessive trait it will only be the expressed phenotype when it is homozygous. Dominant allele phenotypes will show if the genotype is heterozygous.

How alleles and genes related?
Genes and alleles are related because alleles are inside a gene. Genes are made up by alleles. A gene is DNA. The allele is like piece of DNA inside a gene.
What does genetic recombiation mean?
Genetic recombination is the process by which two DNA molecules exchange genetic information. This process results in the production of a new combination of alleles.
During which process do rare changes in DNA result in genetic diversity?
Mutagenesis
What are two common uses for DNA testing?
DNA Fingerprinting, and Testing for alleles.
What does the term independent assortment of alleles mean when used in the context of genetics?
It is basically a long process of your strands of DNA combining together after a long period of time.
Are alleles different forms of a gene?
No, alleles are different forms of a gene. The gene is the portion of DNA/RNA that codes for a particular trait (chain of proteins). The alleles are the possible code bits that could be in that part of the DNA and different alleles will result in different traits being expressed. E.g., part of your DNA codes for your eye color, and in that part there are a number of different alleles that could be there. A certain allele might make you blue-eyed, while another would make you brown-eyed, etc. This is something of a simplification as many traits are expressed via multiple alleles, but that is the general idea.
3 What is the name of the process in which DNA is copied into a form of RNA?
transcription
When not in the process of division DNA exists in the form called?
Double helix.
