What are alleles in biology? Genetic Information: Our DNA is the genetic information found in every cell of our body, which we received from our mother and father through the process of reproduction. DNA holds our genes, which determine aspects about us such as our hair and eye color, heigh...
High voltage is applied so that the fluorescent DNA fragments are separated by size and are detected by a laser/camera system. Data analysis software provides a profile of the separation, precisely calculates the sizes of the fragments, and determines the microsatellite alleles present in the ...
SNPs (often pronounced “snips”) are single base-pair changes in DNA that occur at specific places in the genome. For example, most individuals carry the C nucleotide at a specific base position in the genome, but in a minority of indi...
What are genes? What are alleles?Question:What are genes? What are alleles?Down Syndrome:Down syndrome is a genetic disorder characterized by the appearance of another chromosome 21 copy in the karyotype of the individual with the disorder. The occurrence of three copies of chromosome 21 also pr...
There is also genetic testing to look for certain alleles which correlate with Celiac disease, but that is not a reliable diagnosis in and of itself. However it’s diagnosed, only a very small portion of the population – in the low single digits percentage – tests out positive for these....

What are dominant alleles and recessive alleles? A dominant allele will lead to expression of the dominant trait in both homozygous dominant and heterozygous individuals. A recessive allele will only lead to expression of a recessive trait in homozygous recessive individuals.What...
Incomplete Dominance Examples in Humans One example of incomplete dominance in humans is wavy hair. There are two alleles for hair texture, curly or straight. If a person is homozygous for either type of these alleles, they either have curly hair or they have straight hair. However, if a pe...
DNA, Genes, Alleles and Chromosomes The nucleus of the cell containsdeoxyribonucleic acid(DNA) – the "blueprint" of a living organism. Genes are snippets of DNA in the chromosomes that influence inheritable traits such as natural athletic ability. Different forms of genes are called alleles. M...
Even within the myeloid lineage, analyses of these three Idh-mutant mice suggest that these alleles produce phenotypes of varying severity, correlating with 2-HG levels, with Idh2R172 exhibiting the most severe phenotype. We showed that altered DNA and histone methylation; partially block ...
