Final answer:
In Biology, female sheep's egg cells (gametes) have 26 chromosomes. As gametes are haploid cells with half the total number of chromosomes, adult sheep somatic cells have 52 chromosomes, which is answer C.
Step-by-step explanation:
The subject of this question is Biology, specifically related to chromosomes and cell reproduction. If female sheep have egg cells with 26 chromosomes, we are discussing their gametes, which are haploid cells containing half the total number of chromosomes present in somatic (body) cells. Since the egg cells have 26 chromosomes, the adult sheep, being a diploid organism, would have 52 chromosomes (26 pairs) in each of its somatic cells, as each cell must have two sets of chromosomes – one from each parent. Therefore, the correct answer is C. 52 chromosomes in each cell of an adult sheep.
