Giant chromosomes, such as lampbrush and polytene chromosomes, are significantly larger in size compared to normal chromosomes. Lampbrush chromosomes are found in oocytes of various vertebrates, while polytene chromosomes are common in dipteran flies like Drosophila. These specialized chromosomes pl

Polytene chromosomes, giant chromosomes found in salivary glands of insects like fruit flies, exhibit unique banding patterns consisting of bands and interbands. Researchers like Balbiani have studied these chromosomes, noting over 5000 bands in Drosophila. The uncoiling of chromomeres in bands form

The concept of genetic linkage is explored through experiments in maize and Drosophila, showcasing how specific traits are inherited together due to their close association on chromosomes. In maize, the phenomenon of linkage is demonstrated through color and endosperm traits, while in Drosophila, co
