Answer:

we can ask questions related to karyotype, such as: how many chromosomes a certain species have? known as chromosome count, how large are the chromosomes of one species compared to another? what are the taxonomic relationships between some species?

Explanation:

when we observe chromosomes, we´re describing the karyotype, which varies among different species, the study of the karyotype is known as karyology, and thought some techniques such as stainings, can provide information such as number of chromosomes, positioning of centromeres, differences in size or distribution of heterochromatic region, taxonomic relationships, among other. in humans, there are 46 chromosomes, and we can see for example the sex chromosomes, and determine the sex and other physical characteristics
