Suppose that the great green galoofus lizard has fifty-two chromosomes in the nucleus of its body or somatic cells. how many chromosomes will be in the unfertilized egg of a great green galoofus lizard? a) 13 b) 26 c) 52 d) 104

they fuse to form they have half as many chromosomes as a somatic cell of the same individual. b

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
