The correct answer is C. Gardeners choose which plants they let reproduced based on the plant traits.
Explanation:
In general, selective breeding involves the intervention of humans in the reproduction of species, this includes mainly plant and animal species. Moreover, in selective breeding, humans choose which specific species or individuals reproduce to favor certain traits. For example, a farmer might allow only the biggest cows to reproduce because this will lead to bigger calves. In this context, the option that shows selective breeding is C because this shows the intervention of humans in reproduction by selecting the individuals that will reproduce.

Answer:
Smooth and green seeds
Smooth and yellow seeds
Wrinkled and green seeds
Wrinkled and yellow seeds
Explanation:
This is a typical dihybrid cross involving two linked genes; one gene coding for seed texture and the other for seed colour. The allele for Smooth seed (S) is dominant over the allele for Wrinkled seed (s) in the first gene while the allele for green seed (G) is dominant over the allele for yellow seed (g) in the second gene.
The cross is between a heterozygous smooth, green plant and a homozygous recessive wrinkled, yellow plant
According to the law of independent assortment, each parent will undergo meiosis to produce the following gamtes with genotypes:
SsGg: SG, Sg, sG, sg
ssgg: sg, sg, sg, sg
Using a punnet square to perform a cross between these gametes ( check attached image), a total of 16 offsprings with four different phenotypes will be expected. The phenotypes are as follows:
SsGg: Smooth and green offsprings (4)
Ssgg: Smooth and yellow offsprings (4)
ssGg: Wrinkled and green offsprings (4)
ssgg: wrinkled and yellow offsprings (4)
The answer is anaphase.
Speaking of mitosis, which is a cell division of a single cell into two identical daughter cells, it consists of 4 phases - prophase, metaphase, anaphase, and telophase and cytokinesis. Chromatids are present only in metaphase and anaphase. During metaphase, sister chromatids join together. During anaphase, sister chromatids separate from each other to the opposite sides of the cell.
