New clues from 2 million-year-old tooth enamel tell us more about an ancient relative of humans Researchers have extracted 2-million-year-old protein remains from Paranthropus robustus teeth to reveal biological sex and genetic variability.

#Clonal crops, such as #grapevine and #potato have amplified genomic #heterozygosity in clonal propagation, we studied #genetic & #epigenetic landscapes of #hemizygous genes in #crops with contrasting reproductive systems.
