Heritable variation is required for which of the following
Which of the following statements is supported by this observation? A) Natural selection had not occurred very frequently in the wild dog populations. B) There was enough heritable variation in the wild canine species to create a variety of features. C) Heritable variation is low; otherwise the there would be more wild dog species.Terms in this set (17) Which of the following pieces of evidence most strongly supports the common origin of all life on Earth? -all organisms reproduce. -all organisms use essentially the same genetic code. -all organisms have undergone evolution. -all organisms require energy. -all organisms show heritable variation. Outline the process of evolution through natural selection. Understanding: Natural selection can only occur if there is variation among members of the same species. 1. populations produce more offspring than can survive; 2. individuals show variation in heritable traits; 3. there is a struggle for survival, often due to competition for resources;

Natural selection needs some starting material, and that starting material is heritable variation. For natural selection to act on a feature, there must already be variation, and that variation must be able to be passed on to offspring.The greater the heritability of a population’s phenotypic variation, the more susceptible it is to the evolutionary forces that act on heritable variation. We call the diversity of alleles and genotypes within a population genetic variability.

Asexual reproduction and cloning do not require heritable variation. Explanation: Heritable variation is required for evolution. Evolution is the process by which species change over time and adapt to their environment. Without heritable variation, there would be no genetic diversity that could lead to the emergence of new traits and new species.Which of the following statements is an accurate combination of postulates 1 and 2 of natural selection? Heritable variation does not exist among individuals in a population. Drug resistance exists among all individuals in a population. Heritable variation exists for traits among individuals in a population. The appropriate unit for defining and measuring genetic variation is the: Population.
