Calculation of expected and observed heterozygosity ...

(Posted by @timothymillar). The observed heterozygosity is a measure of heterozygosity in the real population and is typically estimated from a sample of multiple individuals of that population. In diploid populations the observed heterozygosity is simply the proportion of heterozygous individuals (see scikit-allel function).. In polyploids the concept of heterozygous or …

Cone Crusher

Cone crushers were originally designed and developed by around 1920 and therefore are often described as cone crushers. As the mechanisms of crushing in these crushers are similar to gyratory crushers their designs are similar, but in this case the spindle is supported at the bottom of the gyrating cone instead of being suspended as in larger gyratory crushers.
