(a.) The condition of having two or more kinds of flowers which differ in regard to stamens and pistils, as in the aster.
(a.) Characterized by heterogamy.
Example Sentences:
(1) It is proposed that, by reducing mating speed, inbreeding changes the rate of this sequence but not its pattern, so the apparent level of heterogamic mating will increase during inbreeding, for a fixed observation period.
(2) Heterogamous marriages, by contrast, show a higher divorce rate and tend to leave therapy prior to termination.
(3) In a multiple-choice mating between two genotypic strains differing in their level of sexual vigor, there is a sequence from heterogamic to homogamic mating.
(4) Observations on the genesis of the ascus by light microscopy and transmission electron microscopy provide no evidence for, what some earlier workers in this field have presumed to be, heterogamous conjugation between a mother cell and its bud.
(5) This principle states that a biallelic polymorphism is maintained if the heterozygote is superior in its degree of "heterogamous self-replication" to the degrees of "autogamous self-replication" of the corresponding homozygotes.
(6) We have observed directly females of Drosophila paulistorum semispecies in choice experiments with both homogamic and heterogamic males.
(7) Younger males increasingly tended to select brides of their own age group until the 1960s, while older males have been increasingly heterogamous since World War II.
(8) Previous heterogamic copulatory experience did not change the degree of sexual isolation; however, females with homogamic copulatory experience showed a significantly higher preference for homogamic males.
(9) An alternative explanation to the pheromonal control of mating through chemoreceptor saturation proposed by Averhoff and Richardson (1974) is offered for the apparent rise in heterogamic mating in their experiments, after several generations of full-sib mating.
(10) Thus these unions are termed "symptom object" relationships and are characterologically heterogamous.
(11) In most of the crosses homogamic matings outnumber heterogamic ones, and deviation from randomness is statistically significant in 11 of 20 crosses.
Heterogamy
Definition:
(n.) The process of fertilization in plants by an indirect or circuitous method; -- opposed to orthogamy.
(n.) That form of alternate generation in which two kinds of sexual generation, or a sexual and a parthenogenetic generation, alternate; -- in distinction from metagenesis, where sexual and asexual generations alternate.
