New Study Links Ancient Human Remains from Zlatý kůň and Ranis in Genetic Findings

After modern humans left Africa, they met and interbred with Neandertals, resulting in around two to three percent Neandertal DNA that can be found in the genomes of all people outside Africa today. However, little is known about the genetics of these first pioneers in Europe and the timing of the Neandertal admixture with non-Africans.

Study Reveals Genetic Basis of Sweetpotato Flesh Color Regulation

Sweetpotatoes are an agricultural powerhouse that feeds millions globally. However, their complex genetics make it challenging for breeders to understand and improve traits like yield, disease resistance, and nutritional content. A new study reveals insights into the significance of leveraging "allele dosages" in sweetpotato breeding practices.
