In particular whether one or several males succeed in mating with
a single queen affects the average relatedness among workers 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.
The researchers point out that it generally becomes difficult to study mammalian mate choice because dominant males among them often chase away others for access to female partners, which makes it hard to tell whether females are choosing to mate with certain males or are merely mating with
them by default.
The UL-listed unit features mechanically keyed housing to ensure proper mating and enables rotational blind mating with
approximately 0.09 in.
One focused on the possible value of a detached organ as a barrier to the recipient mating with
(or Ms.) Right Mating with
just anyone isn't good enough.
Scientists believe animals stand to have genetically varied offspring by mating with
an individual unlike most of the population.
If heritable traits of one sex, often called preferences, result in proportionately greater chances of mating with
those individuals of the other sex that possess complementary heritable traits, often called ornaments, then the progeny of these matings tend to inherit genes for both traits.
None of the 5 females whose matings ended between the 1400 h and 1700 h censuses were mating with
new partners during the 1700 h census, but 3 of them were observed mating the following day.
Winners do the lion's share of mating with
available females, whom the dominant males guard from skulking suitors.
In contrast, males appeared to court and attempt mating with
every female encountered (virgin and mated), and a majority of males paired with more than one virgin female mated more than once (64.5%).
The punch line sounds like a joke, but ligers--produced by a female tiger mating with
a male lion--are actual animals and one of the world's more bizarre-looking hybrids, or mixed animal species.
The Basis for Mating Discrimination.--In pairings with silenced Canton-S males, 13.2% (17/129) of Canton-S females mated within 1 h, compared with 1.7% (2/119) mating with
silenced Tai-Y males (P [is less than] 0.001, Fisher's exact test).
As such, it is critical that the laboratory reared males are as competitive as wild males in successfully mating with
Previous research had indicated that males increase chances of mating with
a particular female by spending time with her.
