"There has been a lot of work in the past on humans selecting for appearance of animals," says biologist John Fryxell of the University of Guelph in Canada, who was not involved in the study.
Being a condition transmitted by one (or more) recessive gene(s), leucism would appear in camel herds only at a very limited frequency in natural reproductive conditions, whereas the selection for leucism can be obtained in 'close' herds where the reproduction is selected for the appearance of recessive phenotypes.
The haploid test isolates were purposely selected for their appearance in culture (fluffy, of limited rhizomorph growth and coloured white or off-white with minimal dark pigmentation) to contrast with that of the diploid isolates.
Sensory analysis was carried out for selected extrudates for appearance (color, porosity), taste (bran flavor, bitterness and sweetness), off-odor, texture (hardness, crispness and brittleness) and overall acceptability.
In addition, females don't select for physical appearance to the degree that men do.
"The 20-year-old locally-born batsman had been selected for his first senior appearance in any format because Alviro Petersen was unable to return from South Africa in time to take his place in the team.
He was selected for his eighth All-Star appearance.
Mature eggplants fruits were selected for uniformity in size, appearance, and the absence of physical defects.
The 180° arc of the turn was selected for assessment by the appearance of footsteps at the marker region.
Events selected for measurement (pole-bud appearance, membrane reaching yolk, pole cell invagination, amnioproctodeal invagination, amnioserosa exposure, clypeolabrum retraction, clypeolabrum and ventral lobes being even, heart-shaped midgut, and the filling of the trachea) were identified by hand using a graphical user interface.
