She inherited brown eyes, a dominant allele in both her parents.
Each allele has two forms which are known as alleles. Alleles play an important role as to which characteristics either from mother or father will be passed along to the next generation. The way in which alleles are expressed is the study of genetics.
Recessive alleles are only expressed in the phenotype if the organism is homozygous for the recessive allele (assuming diploidy). If the trait is sex-linked, then it will always show up in males if passed.
Brownian motion, named after botanist Robert Brown. The motion is also known as pedesis which translates from Greek as 'leaping'.
Natural selection acting on a single-gene trait can lead to changes in allele frequencies within a population. If individuals with a certain allele have a selective advantage, they are more likely to survive and reproduce, leading to an increase in the frequency of that allele in the population over time. This process is known as directional selection.
Unless there are factors such as mutation, genetic drift, gene flow, or natural selection that can cause changes in allele frequencies within a population. This concept is known as the Hardy-Weinberg equilibrium, which describes the conditions under which allele and genotype frequencies remain stable over time in a population.
Generation-to-generation change in allele frequencies in a population is known as evolution. This change can be the result of various factors such as natural selection, genetic drift, gene flow, and mutation. Over time, these processes can lead to the emergence of new traits and variations within the population.
The change of genetic information within an organism is known as a genetic mutation. It may also be refereed to as a change in allele frequencies when populations are examined.
The principle is known as Hardy-Weinberg equilibrium. It states that in a non-evolving population, allele frequencies will remain constant from generation to generation unless factors such as mutation, natural selection, genetic drift, gene flow, or non-random mating disrupt the balance.
Genetic drift. It refers to the random fluctuation of allele frequencies in a population due to chance events, particularly in small populations. Genetic drift can lead to the loss or fixation of alleles over time.
This is known as genetic drift. It refers to the random changes in allele frequencies that can occur within a small population due to chance events.

Random changes in allele frequencies in small populations are known as genetic drift. Genetic drift occurs due to chance events, leading to unpredictable fluctuations in the frequency of alleles within a population. In small populations, genetic drift can have a significant impact and may result in certain alleles becoming more or less common or even being lost altogether over time.
Genetic drift is the random change in allele frequencies in a population. It is caused by chance events and has more pronounced effects in small populations where genetic diversity is lower. Over time, genetic drift can lead to the loss of certain alleles or fixation of others in a population.
known as genetic drift. It is a random process that can lead to the loss or fixation of certain alleles in a population over time due to chance events. It is particularly important in small populations where random fluctuations can have a greater impact.
This concept is known as the Hardy-Weinberg equilibrium. It states that, in the absence of evolution forces, allele frequencies will remain constant over generations in a population. It can be used to predict the frequencies of different genotypes in a population if certain conditions are met.
