The phenotypes for a certain trait in a population

What else can I help you with?
What can you learn from looking at phenotypic distribution?
nothing to learn scientist lean not people! valerie
What Does the phenotypic distribution look like in a population that is not undergoing natural selection for a certain trait?
The distribution will center towards hetrotrophs and thus dominant phenotypes. The distribution approaches all dominant phenotypes
What type of distribution curve can be seen with polygenic inheritance?
A bell-shaped curve (normal distribution) can be seen with polygenic inheritance, where phenotypic traits are influenced by the combined effects of multiple genes. This results in a continuous range of phenotypic expression, with most individuals clustering around the mean value.
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.
A bell shaped curve of phenotypic variation is a representation of?
A bell shaped curve of phenotypic variation is a graphical representation of the distribution of a trait within a population. It shows that most individuals in the population have an average value for the trait, with fewer individuals on the extreme ends of the spectrum.
What does phenotypic distribution look like?
Look at the distribution of male height for instance. The mean of this normal distribution is around 5' 10''. So that means about 69% of men are within one standard deviation of this mean. If you saw a sample of men standing on bleachers it would look exactly as a Bell curve looks; normally distributed.
How might the extinction of downy woodpeckers affect the phenotypic distribution of gall flies?
Thanks!0 CommentsDowny woodpeckers are the main predators of gall flies, their extinction could lead to a rise in gall flies
What type of selection always results in the narrowing of the bell curve distribution of alleles?
Directional selection always results in the narrowing of the bell curve distribution of alleles. This occurs when individuals at one extreme of the phenotypic range have a higher fitness, causing the frequency of the alleles associated with that extreme to increase in the population over time.
What is a phenotypic manifestation?
A phenotypic manifestation refers to the physical characteristics or traits that result from the expression of an individual's genes. These traits can include features like eye color, height, and disease susceptibility. Phenotypic manifestations are observable characteristics that can be influenced by both genetic and environmental factors.
Are phenotypic ratios are always the same as genotypic ratios?
No, phenotypic ratios are not always the same as genotypic ratios. Phenotypic ratios are based on the physical appearance of individuals, while genotypic ratios are based on the genetic makeup of individuals. Various factors such as dominance, incomplete dominance, and gene interactions can result in differences between phenotypic and genotypic ratios.
What kinds of phenotypic are the results of evolution?
Changes that are genetic
What is the phenotypic ratio of the offspring when a tall man marries a short woman?
The phenotypic ratio of the offspring when a tall man marries a short woman is 3:1 (tall/short). The phenotypic ratio is figured by using the punnet square with the dominant allele for tall and the recessive allele for the short gene.
