Answer:
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
Explanation:
Evolution, in genetic terms, involves a change in the frequency of alleles in a population over time. What are the sources of genetic variation? Three sources of genetic variation are mutation, genetic recombination during sexual reproduction and lateral gene transfer.
Answer:
As taxon is part of the taxonomic category it is constructed by individual biological objects. -Species contains a group of individuals with same morphological characters and they can breed among themselves whereas taxon is a group of one or more population of an organism in taxonomical form.
Explanation:
Sister chromatids are separated during meiosis II because homologous chromosomes separate during meiosis I.
<h3>What is Meiosis?</h3>
Meiosis is a particular type of cell division by which gametes (germinal cells are generated) through two division cycles known as Meiosis I and Meiosis II.
During Meiosis I homologous chromosomes are separated, thereby ensuring the correct segregation of sister chromatids during Meiosis II.
In conclusion, sister chromatids are separated during meiosis II because homologous chromosomes separate during meiosis I.
