The answer is C, it results in offspring with genetic variations.
Sexual reproduction is where a male gamete fuse with a female gamete to form a zygote, which is their offspring.
Gamete cells are different to the other somatic (body) cells in an organism, they have only half of the chromosomes. They are products of a kind of cell division called meiosis. They are also said to be haploid cells.
When 2 haploid cells fuse together, the number of chromosomes will add up so that it'll match the correct number of somatic cells of that organism. Because both gamete contains half of the chromosomes, when they fuse together, they produce offsprings with some characteristics from both parents.
The different characteristics from the parents and others are said to have genetic variation. They're different to others in some way, even they're still the same organism.
This can actually help that type of organism survive, for example if a huge disease breaks out, there may be still some organisms with a characteristic which can help them stay alive.
Answer:
One of the parents is heterozygous for red (Rr) and the other is homozygous for white (rr)
Explanation:
The ratio of red flowers to white flowers is roughly 50:50 in this cross (51:47)
Assuming red is the dominant trait, and white is the recessive trait, the parents would be Rr (heterozygous red) x rr (homozygous white).
The resulting punnet square (attached) shows that the genotypes are 50% Rr and 50% rr, which would be 50% red and 50% white. Therefore the parents are RR and Rr.
If red is the recessive phenotype, then the opposite would be true, the white parent would be heterozygous and the red parent would be homozygous.
