1 answer:

5 0

Both being forms of reproduction posses some characteristic advantages.
<span>> Asexual reproduction is an easy way to produce more clones (group of clones refereed as rummest). So at the time of calamity asexual reproduction ensures that more and more individuals of same generations are produced overtime with same genetic content and is helpful in survival of any species. Example : E.coli reproduces every 20 minutes through asexual reproduction. </span>

<span>> Sexual reproduction is a way to ensure variability in an organism. It generates variation in the offspring through crossing over and recombination that makes the progeny more suitable to the environmental features and thus is effective means for survival.</span>

Why is mitosis incompatible with the production of sperm and oocytes

Naily [24]

Answer:

Mitosis creates diploid cells, while gametes (sperm and oocytes) are haploid cells

Explanation:

Mitosis is the process by which somatic (non-germ line) cells replicate, and two identical cells, called daughter cells are produced from each division. These cells are diploid, meaning that the cell has paired chromosomes. Meiosis is the process by which gametes, sperm cells and oocytes, are produced and these cells must be haploid, or contain unpaired chromosomes, so that when fertilization occurs, the chromosomes from the sperm cells and the chromosomes from the oocytes can recombine to create unique pairs of chromosomes for the resulting zygote. Thus, mitosis will never be able to create germ cells as germ cells must be haploid.

<em><u>The Grants documented that natural selection takes place in the wild finch population frequently, and sometimes rapidly. </u></em>
The Grants' work showed that variation within a species increases the likelihood of the species' adapting to and surviving environmental change.
