If a queen were to mate with four males and there was a matched mating
, only 12.5% of the offspring would be diploid males.
During the last stage of colony sexuals are produced and mating
is done after mating
queens went to diapause and remaining males and workers die in the colony.
Since each mating
offers an opportunity to father off-spring, males can generally increase their fitness by mating
with many females, and high mating
rates are thus typically associated with high male reproductive success.
"Generally, those males exposed to other males prior to mating
reproduced more successfully than those who had not.
In spite of this diversity, multiple mating
involving reciprocation, long-term storage of allosperm, and the ability to digest allosperm are common among many hermaphrodite species (Baur, 1998; Michiels, 1998).
In spite of the attention paid to the reproductive behavior of spiders, relatively little is known about either the frequency with which males recharge their pedipalps or the mating
rates of species that can mate several times.
The females prefer jacks to avoid physical abuse during mating
To further confirm that IUM 99-3617 was MATa in mating
type, MFa and STE 20a genes were sequenced by an ABI PRISM 310 automatic sequencer using Big Dye Terminator (Applied Biosystems, Monza, Italy) and the primers, forward and reverse strands previously reported (4).
MaLes have wider heads and stronger jaw muscles than females and these are used in mate-to-mate combat, especially when females are close to mating
. Genetic analysis also shows that most monogamous pairs of sleepy lizards produce litters fathered by one male, suggesting successful mate-guarding.
Scientists believe animals stand to have genetically varied offspring by mating
with an individual unlike most of the population.
A unique, patented RF connector series with slide-on mating
and a floating front end that moves during the mating
process has been developed to solve this problem.
So although Sweitzer has come close to catching the creatures mating
, he has had to settle for stumbling upon pairs that seem to be on the verge of reproduction--animals that provide only indirect hints about how por- cupines find and pick mates.
