SEXUAL REPRODUCTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which process creates genetically DIFFERENT offspring?
A
sexual
B
asexual
Explanation: 

Detailed explanation-1: -Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.

Detailed explanation-2: -Sexual reproduction also results in genetic variation among siblings. When a parent forms a gamete, only one chromosome from each homologous pair is included at random. So, an offspring might inherit a different combination of chromosomes (and alleles) compared to its siblings.

Detailed explanation-3: -Reproduction is the production of offspring. There are two main forms: sexual and asexual reproduction. In sexual reproduction, an organism combines the genetic information from each of its parents and is genetically unique. In asexual reproduction, one parent copies itself to form a genetically identical offspring.

Detailed explanation-4: -Recombination increases genetic diversity by putting pieces of slightly different chromosomes together. Next, the newly recombined homologous chromosomes are divided into two daughter cells. Then the sister chromatids are pulled apart into a total of four reproductive cells.

Detailed explanation-5: -Asexual reproduction generates offspring that are genetically identical to a single parent. In sexual reproduction, two parents contribute genetic information to produce unique offspring. Sexual and asexual reproduction have advantages and disadvantages-which is why some organisms do both!
