Question

What are maternal-effect genes?

They are genes that control early embryogenesis and development
of female but not male offspring.



They are genes that control early embryogenesis and development
of male but not female offspring.


They are genes that are transcribed in the nuclei of the
developing embryo giving rise to fourteen segments in
Drosophila.


They are genes that control early development that are
dependent on the deposition of their products (mRNA, transcription
factors, various structural proteins, etc.) in the egg by the
mother.

Answer 1

They are genes that are transcribed in the nuclei of the developing embryo giving rise to fourteen segments in Drosophila.

Step-by-step explanation:

Maternal effect genes:

- They code for RNAs and proteins that play a key role in the early stages of embryogenesis (cell division, clivating pattern, axial axis orientation)

- Defective mutant alleles are usually lethal or have dramatic effects on the offspring phenotype
