- Somatic cells in organisms of a particular diploidplant species normally have 14 chromosomes. Thechromosomes in the gametes are numbered from 1through 7. Rarely, zygotes are formed that containmore or fewer than 14 chromosomes. For each of thezygotes below, (i) state whether the chromosomecomplement is euploid or aneuploid; (ii) provideterms that describe the individual’s genetic makeupas accurately as possible; and (iii) state whether ornot the individual will likely develop through theembryonic stages to make an adult plant, and if so,whether or not this plant will be fertile.a. 11 22 33 44 5 66 77b. 111 22 33 44 555 66 77c. 111 222 333 444 555 666 777d. 1111 2222 3333 4444 5555 6666 7777A diploid cell has 4C genetic material and 16 chromosomes at the start of cell division.
