Mendel Genetics/Genetics Intro

Genetic Traits
... Women have two X chromosomes, one of which usually carries the allele for normal color vision. Therefore, few women are colorblind. Men only have one X chromosome, so if they carry the allele for colorblindness, they will exhibit this trait. Thus, colorblindness is seen more frequently in men than i ...

what causes dominance
... Recessive alleles are found only where two copies are present. So you could imply here that dominant refers to the causal effect of a single allele. What was I going on about again? Oh yeah.... Mendel used d/r to refer as traits. This is on appearances only, and describes no properties to hidden all ...

Population Genetics and Evolution
... Mutation is a fairly uncommon occurrence, which will not significantly change allele frequencies itself, but is the main source of change and therefore evolution. Migration of individuals in or out of a population is the cause of gene flow, which introduces new alleles to a group and removes others. ...

Multiple Alleles

If one were to mate a homozygous red four o'clock flower with a homozygous white four o'clock flower one would expect all the F1 offspring would be red, since red is dominant t ...
