AYALA,F.J., 1970 Population fitness of geographic strains of Drosophila serrata as measured by.T numerous tréatments of this concépt from both theoreticaI and experimen-.Drosophila, on thé other hand, havé been quite divérse, ranging from thé.

The upper pórtion of each cagé was an invérted 500-ml polypropylene. The flask pórtion of the cagé provided additional airspacé and a suitabIe holding chamber fór. The semiweekly cóunts were totaled intó a weekly próductivity. The flask wás removed, pIugged with the rayón ball and á flask flies wéight was taken. The. Individual replicate vaIues are givén in the APPENDlX, but for purposés of comparison thé replicate. The particular compound strain utilized here is designated C45. The fitness óf a strain wás calculated as thé proportion of wiId flies. Fecundity estimates wére made by cóunting eggs immediately aftér. The component dáta for stráin A9a are unavailable, and for line A20-17 no. Strains such ás HET IV ánd AJ14a, which were clearly superior in the compet-. CARSON(1961a) was careful to state that the relative population fitness. However, HARTLand HAYMER (1983) have found no significant correlation. ![]() Another potential probIem for any muItigenerational analysis is thé question of. AZO-17 no mating activity was recorded in more than 20 min of observation. Since this is largely a function of male mating activity, it is not hard to imagine. PROUT(1971) admonished that the relationship between a single fitness com-. CARSON(196lb) indicated, this test seems to be measuring an attribute of a. WRIGHT (1969 and earlier) has pointed out that significant selection occurs. Thanks also tó DRS.L. ![]()
