Sex Determination in Drosophila
Drosophila, commonly known as fruit flies, have long been a staple in genetic and developmental biology research. One of the most fascinating aspects of Drosophila biology is their sex determination process, intricately tied to their genetic makeup. The sex of these tiny organisms is dictated by a single pair of sex chromosomes, X and Y.…

Chick embryo development
Chick embryo development is a fascinating and complex process that involves a series of morphological changes from fertilization to hatching. Chick embryos are an excellent model organism for studying development due to their accessibility and similarity to human development. The development of a chick embryo involves six major steps: fertilization, cleavage, gastrulation, neurulation, organogenesis, and…

Fertilization in Sea Urchin
Fertilization in sea urchins is a complex process that involves a series of steps, beginning with the release of sperm and eggs and culminating in the formation of a zygote. The release of gametes is often triggered by environmental cues, and upon contact, the sperm undergoes a series of changes, including the release of enzymes…
