10 Questions
What is the primary mechanism that prevents polyspermy during fertilization?
Cortical granule exocytosis and modification of the egg's extracellular matrix
What is the significance of the mid-blastula transition in early embryonic development?
It marks the onset of zygotic genome activation
What is the consequence of excessive sperm entry during fertilization?
Chromosomal abnormalities and embryo death
What is the role of cytoskeletal elements during the first cleavages after fertilization?
Positioning and segregating organelles and molecules within dividing cells
What is the significance of germ plasm in specifying germ cells?
It influences germ cell fate
What is the primary function of somatic cells in an organism?
To perform various functions for the organism's growth and development
What is the significance of germ plasm in germ cell specification?
It contains molecules necessary for germ cell development and is inherited from the parent
What is the main difference between germline and somatic cells?
Germline cells produce haploid gametes and contribute genetic information to the next generation, while somatic cells do not
What is the purpose of classical experiments in developmental biology, such as those conducted by Wilhelm Roux and Thomas Hunt Morgan?
To understand the concept of germ plasm and its role in germ cell specification
What is the result of germ plasm segregating into cells during embryogenesis?
The promotion of germ cell development and the continuity of the germline across generations
Learn about the differences between germline and somatic cells, and how germ plasm contributes to germ cell specification. Explore the roles of these cells in reproduction and development.
