The obstruction of adaptation in diploids by recessive deleterious
... A deleterious mutation that is recessive is hidden in individuals containing only one copy (i.e., heterozygotes); however, individuals containing two copies (i.e., homozygotes) suffer negative effects. This class of mutation is responsible for a number of human genetic disorders, including cystic fi ...

Salinity affects durum wheat [Triticum turgidum L. ssp. durum (Desf.)] more than it affects bread wheat (Triticum aestivum L.), and results in lower yield for durum wheat cultivars grown on salt-affected soils.

The genetical theory of social behaviour

We start by reconsidering Hamilton’s (Hamilton 1964 J. Theoret. Biol. 7, 1–16 (doi:10.1016/0022-5193(64)90038-4)) results for selection on a social ...
