Phenotype controlled by multiple genes

Web2. dec 2024 · Pleiotropy occurs when one gene is controlled by multiple alleles and polygenic inheritance occurs when one trait is controlled by multiple genes. Incomplete dominance is the blending of alleles, resulting in a phenotype that is in between the two extremes.

Web13. apr 2024 · Intriguingly, the transcription factors PAX4 and α-PALNRF-1 control the expression of proteasome among other genes in a combinatorial manner, driving cellular adaptation to muscle denervation. Consequently, PAX4 and α-PALNRF-1 represent new therapeutic targets to inhibit proteolysis in catabolic diseases (e.g. type-2 diabetes, cancer).

WebProtein synthesis is controlled by genes, which are contained on chromosomes. The genotype (or genome) is a person’s unique combination of genes or genetic makeup. Thus, the genotype is a complete set of instructions on how that person’s body synthesizes proteins and thus how that body is supposed to be built and function.
