Description : What is the difference between a mutation and a genetic variation?
Last Answer : A: A mutation is a change in the DNA sequence, while genetic variation refers to differences in the DNA sequence between individuals in a population.
Description : why does sexual reproduction result in more genetic variation in species?
Last Answer : It combines different sets of DNA, instead of replicating the same set.
Description : How does genetic variation create new species over time?
Last Answer : well they adapt combineing with other spices

Description : In order to see the Hardy Weinberg equation to calculate genetic variation in a population conditions must exist in the population?
Last Answer : All organisms must reproduce
Description : Why does sexual reproduction result in more genetic variation in a species?
Last Answer : It mixes the chromosomes of the two parents
Description : What happens after meiosis to introduce even more genetic variation in sexualy reproducing organisms?
Last Answer : Genetic variation is increased by meiosis Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase
Description : A change in genetic constitution, which arises suddenly and not to segregation and recombination of genes in sexual reproduction is called as: a. Hybridization b. Bud variation c. Mutation d. Non of them
Last Answer : Mutation

Description : The latitudinal extent of India is responsible for the variation in the climatic conditions which prevail in the country. -SST 10th
Last Answer : The Northern plains lie to north of the Tropic of Cancer in the Temperate Zone. The winters are much colder. South India lies below the Tropic of Cancer, in the tropics and gets the direct rays of the sun. Hence it is hot through most of the year. The winters are not so cold.
Description : What is the genetic mechanism that may have been responsible for the base sequence changes between humans and gorillas?
Last Answer : Many genetic changes happened. One involved the joining of two"ape" chromosomes (they have 24 pairs of chromosomes) end to end tomake human chromosome #1 (we have 23 pairs of ... ancestors, even though both peoplesprobably had identical appearance and lived together for severalgenerations of both.
