(D) Mosaic Forming Factors
5 Signs of aging include​

Answer 1

Certain proteins or mRNAs that are regionally localized within the unfertilized egg and regulate development are called (A) Gene Regulators.

• Gene regulators are involved in gene regulation at various stages such as transcriptional, splicing and translation level.
• These regulate the processes in the unfertilised egg.
• Cytoplasmic determinants regulate the gene expression at embryonic stages as these are found in female gametes.
• Morphometric Determinants determine the shape or traits based on evolutionary history.
• The occurrence of two or more sets of genetically different cells in a single body.
