The parent the offspring will be a clone of the parent so lets do the so um so in 10 it says What is the source of variation in a sexual reproductive. It occur in plants a eukaryotic organism as well.

Two reasons for the appearance of variation among the progeny formed by sexual reproduction may be as follows1 The progeny formed by sexual reproduction is the result of the combination of the genetic material from two different individuals.

How does variation occur in asexual reproduction. It does create exact genetic copy -- BEST CHOICE. It splits open releases a daughter cell and dissolves. Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomesThe offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent.

There is no difference in the level of genetic variation produced by the two types of reproduction. All forms of life reproduce through one of two means. They divided as following.

Cases of this sort however being rare in nature. Asexual reproduction occurs when a single organism has an offspring. O It quadruples its DNA and other contents and then divides in four.

Genetic variation occurs mainly through DNA mutation gene flow movement of genes from one population to another and sexual reproduction. Asexual reproduction is a reproduction method used by some living things that allows a single parent to divide and produce progeny. Many scientists believe that HGT and mutation are significant sources of genetic variation the raw material for the process of natural selection in prokaryotes.

The consensus now says that fertilization is two half-se. Sexual reproduction has been a problem to explain because it seems to make more sense for a female to send all of her genes into the future rather than just 50 together with the males 50. As others have stated sexual reproduction is usually better for evolution since it allows for genetic diversity and can result in an organism having a trait which will allow is to be better adapted for an environment or fight off disease easier.

The differences between sexual and asexual reproduction. There is more genetic variation in organisms that reproduce sexually. What happens to the parent cell during binary fission.

If bacteria reproduce through asexual reproduction how does genetic variation occur. Sexual reproduction alllows the mix of genes whereas asexual reproduction does not have genetic shuffling occur. Asexual reproduction involves only one parent with little or no genetic variation while sexual reproduction involves two parents who contribute some of their own genetic makeup to the offspring thus creating a unique genetic being.

Asexual reproduction is the primary form of reproduction for single-celled organisms such as archaea and bacteria. One example of asexual reproduction is binary fission that. As the expected degree of variation between gametes from predominantly asexual organisms is high every sexual event that occurs produces a new unique multilocus genotype.

The only situation in which this argument fails to hold is that of recent asexual lineages being derived from strict selfers. Sexual reproduction increases genetic variation in offspring which in turn increases the genetic variability in species. Asexual reproduction limits the spread of harmful characteristics because the offspring is only inheriting from one parent so therefore it will be inheriting only those characteristics.

Sexual reproduction is a process in which the genetic material from two individuals male and female combine to form the offspring. 1 mutations mitosis gene expression binary fission 1 gene transfer 2. Asexual reproduction is in bacteria.

Asexual reproduction occurs when an organism produces an offspring that is an exact copy of itself with the same genetic material. - making A a possibly choice Asexual reproduction occurs in eukaryotes but not all of them - making b a possible choice c. Advantages and disadvantages of sexual and asexual reproduction.

So its exactly the same a sexual reproduction through binary fission which is the way that it will split apart and budding um it will reproduce and it will be exactly the same. Variation refers to the differences between members of the same species. Due to the fact that environments are unstable populations that are genetically variable will be able to adapt to changing situations better than those that do not contain genetic variation.

Although HGT is more common among evolutionarily related organisms it may occur between any two species that live together in a natural community. Which statement about sexual and asexual reproduction is true. Does variation occur in asexual reproduction.

Here the divide so fast there variations are available within a week. Having variation within a species means that if the. In asexual mode of reproduction variations is possible as here the parent divided up binary either forming 2 daughter cell or multipe daughter cells.

There is a lot of genetic variation in organisms that reproduce only asexually. Continuous variation is variation that has no limit on the value that can occur within a population. Imagine this kind of variability expanded to include all the families you know.

You can see the effects of this genetic variability if you look at the children in a large family and note how each person is unique. Asexual reproduction requires only one parent and the cells divide by budding regeneration or fission.
