What kind of variation must exist in a population that has a wide range of phenotypes?

TestNew stuff! What kind of variation must exist in a population that has a wide range of phenotypes? How can a wide range of phenotypes increase the chances that some will survive? A wide range means that the population has a lot of genetic variation.

Why does a wide range of traits increase the chance that some individuals will survive in a changing environment?

2. How can a wide range of phenotypes increase the chance that some individuals will survive in a changing environment? a. Populations with many phenotypes tend to be very strong and hardy.

What are phenotypic variations?

Phenotypic variation, then, is the variability in phenotypes that exists in a population. For example, people come in all shapes and sizes: height, weight, and body shape are phenotypes that vary. ... All organisms can have phenotypic variation. In plants, flower color and leaf shape are examples of variable phenotypes.

What contains the genetic variation for the entire population?

Population geneticists study the variation that naturally occurs among the genes within a population. The collection of all the genes and the various alternate or allelic forms of those genes within a population is called its gene pool.

What causes variation in the phenotypes in offspring?

Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

What is variation How is variation created in a population?

Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

When the population of a species differs from the other it is termed as variation?

variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).

What are the 3 types of phenotypes?

With one locus and additive effects we have three phenotypic classes: AA, Aa and aa.

What is the importance of phenotypic variation in a population?

Phenotypic variation is essential for evolution . Without a discernable difference among individuals in a population there are no genetic selection pressures acting to alter the variety and types of alleles (forms of genes) present in a population.

What is types of variation?

There are two forms of variation: continuous and discontinuous variation. Characteristics showing continuous variation vary in a general way, with a broad range, and many intermediate values between the extremes.

What is genetic variations?

Genetic variation is the presence of differences in sequences of genes between individual organisms of a species. It enables natural selection, one of the primary forces driving the evolution of life.

What is variation in gene expression?

Variation in gene expression constitutes an important source of biological variability within and between populations that is likely to contribute significantly to phenotypic diversity. Recent conceptual, technical, and methodological advances have enabled the genome-scale dissection of transcriptional variation.

Which type of reproduction is responsible for genetic variation?

Sexual reproduction has the potential to produce tremendous genetic variation in offspring. This variation is due to independent assortment and crossing-over during meiosis, and random union of gametes during fertilization.

What is variation in population?

Genetic variation in a population describes the existence in that population of different alleles, or alternative forms, for a given gene. ... Phenotypic variation describes differences in the characteristics of individuals of a population.

Is all phenotypic variation heritable?

Misconceptions of the Heritability Concept

al., 2008). Heritability is not the proportion of a phenotype that is genetic, but rather the proportion of phenotypic variance that is due to genetic factors.

What are the 3 types of genetic variation?

There are three sources of genetic variation: mutation, gene flow, and sexual reproduction.
