The phenotypes for a certain trait in a population
<3 Joella
What else can I help you with?
What is phenotype frequency?
A ratio of individuals with a particular phenotype to the total number of individuals in the population. Individuals with certain phenotype --------------------------------------------------- (Over) Total # of individuals within the population The distribution of traits in a population
In a population that is not undergoing natural selection for a certain trait what does the phenotype distribution look like?
The distribution will center towards hetrotrophs and thus dominant phenotypes. The distribution approaches all dominant phenotypes
What are the three ways natural selection can affect the distribution of phenotype?
Blah
What phenotype has the greatest frequency in a trait that follows a normal distribution?
a phenotype with the greatest frequency in a trait is enviromental conditions. (G00D !-U<K)
In a population of horses an extreme phenotype is favored and the distribution of genes in that population shifts toward that phenotype This process is called selection?
the process is called an DIRECTIONAL selection.
What can you learn from looking at a phenotype distribution?
nothing to learn scientist lean not people! valerie
What happens when a population is in hardy wienberg equilibrium?
Allele frequency is stable The phenotype frequency does not change.
In a population of horses an extreme phenotype is favored and the distribution of genes in that population shifts toward that phenotype What is the process called?
The process is called directional selection, where one extreme phenotype is favored over others in a population, resulting in a shift in the frequency of genes towards that phenotype over generations.
What are an individual's observable traits called?
genotype or phenotype
The distribution of phenotypes for a typical polygenic trait can often be expressed as?
a bell-shaped curve known as a normal distribution. This distribution shows the range of phenotypes in a population, with most individuals clustering around the average phenotype and fewer individuals at the extremes of the distribution.
What phenotype distribution pattern is common with polygenic inheritance?
A continuous variation of phenotypes is common with polygenic inheritance, often resulting in a bell-shaped curve known as a normal distribution. This means that individuals will exhibit a range of phenotypes with no clear-cut categories.
When the variance calculated from a distribution of phenotypes is zero it means that?
When the variance calculated from a distribution of phenotypes is zero, it means that all individuals in the population exhibit the same phenotype, showing no variability. This lack of variation suggests that the genetic and environmental factors influencing the phenotype are uniform across the sampled population. Consequently, there is no diversity in traits, which can have implications for adaptation and survival.
