Vedclass · Answer

(A) Polytene chromosomes are giant chromosomes found in the salivary glands of Drosophila (fruit fly) larvae and some other dipteran insects,not in the oocytes of amphibians.Lampbrush chromosomes are observed in the diplotene stage of meiotic prophase-$I$ in the oocytes of many vertebrates,including amphibians.Submetacentric chromosomes have a centromere slightly away from the center,resulting in unequal arms,which gives them an $L$-shape during anaphase.Allosomes are the chromosomes that determine the sex of an organism,commonly known as sex chromosomes.Therefore,the incorrect match is Polytene chromosomes - Oocytes of amphibians.
