The process that the cells of a zygote become specialized after it is formed is called differentiation. The other choices given are for other processes. The correct choice is number 4.
First we establish a table of genotypes and phenotypes:
genotype phenotype
AA type A
BB type B
AB type AB
Homozygous type A has genotype AA
Homozygous type B has genotype BB
Now we make the punnett square
A A
B AB AB
B AB AB
So we see that all (100%) of outcomes are type AB.
The correct answer is: 3.Experimenters show a link between adult-onset diabetes and obesity.
