Gene dominance is when genes compete with one another to exhibit traits from either parent. Complete dominance is when one allele for a gene is dominant and turns off the other allele for the gene. Incomplete dominance is when neither gene is dominant over the other and the genetic result is...
alleles for a certain gene is heterozygous. So here are some possibilities of eye colour below: A person with two blue alleles will have blue eyes. A person with two brown alleles will have brown eyes. A person with one blue allele and one brown allele will have… Brown Eyes! Yes, this...
What is a dominant allele? Define allele, gene, dominant, and recessive as they relate to patterns of inheritance. Explain the difference between a dominant and a recessive condition. Provide an example. What is a recessive allele? What is the ...
What term describes a gene that is able to affect multiple phenotypic characters? What is the term for the trait not expressed when another allele determines the phenotypes, masking its expression? What is it called when two different genes, when paired, blend together and produce a ...
acid), a complex molecule that codes genetic information for the transmission of inherited traits from male parent and female parent. Alleles are also genetic sequences, and they too code for the transmission of traits from parents. So, what it is the difference between a gene and an allele?
A gene is a portion ofDNAthat determines a trait. A trait is a characteristic, or a feature, passed from one generation to another, like height or eye color. Genes come in multiple forms or versions. Each of these forms is called an allele. For example, the gene responsible for the ha...
The transcriptional factor LBP-1c/CP2/LSF gene on chromosome 12 is a genetic determinant of Alzheimer's disease Although the varepsilon4 allele of the apolipoprotein E gene appears as an important biological marker for Alzheimer's disease (AD) susceptibility, other g... Lambert Jean-Charles,G...
“The gene is a union of genomic sequences encoding a coherent set of potentially overlapping functional products.”Although this may not be exactly what you want in a definition, it is an excellent place to start.If you would like to learn more about ENCODE and modENCODE, check out the ...
One allele may be dominant while the other is recessive, eye color often being cited, with the brown allele being dominant over the blue allele. This phenomenon has been modeled by the Punnett square for almost a century, before any real knowledge of DNA. As the square suggests, two parents...
Alleles are the versions of the gene that the organism receives from its parents. Each organism will get one allele from each parent. Each parent contributes half of the chromosomes for the offspring, and their chromosomes match up to provide the two alleles needed for each gene. There are...
