Sexual reproduction promotes diversity of charecters …

Sexual Reproduction involves two parents, thus it involves two different Chromosomes. The offsprings inherit a nuclear set with traits from both the parents. Hence variation arises. Let us look at this way.  Let's take Chromosome 19 (That's the chromosome which decides the colour of your hair.) Your mom is Blonde and has a genotype of BB  Your dad is a Brunet and has a genotype bb. B is the dominant allele while 'b' is the recessive allele. Let's make a Punnett square to see what your genotype. refer (Punnett Square 1)  So you see, You are more likely to be a Blond but since you have a mixed phenotype, it is possible that your future progeny may receive the recessive trait and be brunet.  Suppose you marry a person of a similar mixed Phenotype, hence he/she is also Bb.  (Refer Punnett Square 2) Also, the Nuclear proteins, Adenine, Guanine, Cytokinin and Thymine change their orders to form different gene codes. This also brings variation. Read more on Brainly.in - https://brainly.in/question/1729413#readmore
