What's the difference between offspring and polytocous?
Offspring
Definition:
(n.sing. & pl.) That which is produced; a child or children; a descendant or descendants, however remote from the stock.
(n.sing. & pl.) The act of production; generation.
(n.sing. & pl.) Origin; lineage; family.

(9) Subcutaneous polymorphic sarcomas were induced in 8 out 27 offspring of syrian golden Hamsters after treatment of pregnant mother animals at day 15 of gestation with Adenovirus 12.
(10) Here we show that the subsequent survival and reproductive success of subordinate female red deer is depressed more by rearing sons than by rearing daughters, whereas the subsequent fitness of dominant females is unaffected by the sex of their present offspring.
(11) The residual values were positively correlated in parent-offspring pairs and among sibs, both those presumed to be living together and those presumed to be living apart.
(12) The five offspring are ancestors of all known carriers.
(13) We have studied the effect of ampicillin and cloxacillin treatment of mice in the final week of pregnancy on the development of the lymphatic system of their offsprings.
(14) It was caused at the frequency close to 100% in dysgenic offsprings reared above 25 degrees C, of which gonads were morphologically clearly different from those of usual GD sterility, whereas there was no indication of GD-3 sterility at temperatures below 24 degrees C. Temperature sensitive period of GD-3 sterility was estimated to the prepupal stage by shift-down experiment.
(15) The effects of repeated N2O exposures were investigated for offspring of mice exposed to air or N2O (5%, 15%, or 35%) for 4 hours per day on days 6 through 15 of pregnancy.
(16) Whether normal individuals with such a duplication carry increased risk of having offspring with an obesity syndrome is yet to be determined.
(17) Offspring of marmosets reached adult values of 14CO2 exhalation at 8 days postnatally when using [14CO2]-methacetin as substrate and at 30 days postnatally using [14C2H5]-phenacetin in the breath test.

(20) Such conditions may influence the personality of offspring of deaf-mute people.
Polytocous
Definition:
(a.) Bearing fruit repeatedly, as most perennial plants; polycarpic.
(a.) Producing many or young.
Example Sentences:
(1) In polytocous species, animals with reduced birth weights are associated with reduced neonatal survival, which may be related to substandard placental function.
(2) This is particularly true for polytocous species, where it may be necessary to achieve some regulation of litter size by differential embryonic mortality.
(3) In the rat, as in most other polytocous species, fetuses tend to be relatively evenly spaced along the uterine horn, perhaps to minimize possible effects of local overcrowding on placental function and fetal growth.
(4) The pig is an excellent animal in which to study the control of folliculogenesis in a polytocous species, and particularly to examine the inter-relationships between follicles from the same animal.
(5) Although the rat is a polytocous rodent, the female has a regular ovarian cyclicity of 4 or 5 days, with distinct proestrus, estrus, and diestrus phases.
(6) A special problem in prenatal toxicity is the inter- and intralitter variability of the toxic manifestation (especially in polytocal animals).
(7) We examined whether or not the sex of the fetuses of polytocous animals distributes randomly in the position along the uterine horn in 255 mouse litters.
(8) This procedure is pertinent especially for polytocous species such as swine and poultry, for which the occurrence of full-sib families makes the inclusion of dam effects in the model necessary and tests are completed throughout the year.
(9) This model is unique in that atresia can be induced in the single DF of a primate species, and thus avoids the disadvantages inherent to studying atresia of heterogeneous follicles in polytocous species.
(10) This procedure, specific for a hierarchical portion of a model relevant to many animal breeding populations, is pertinent especially for polytocous species such as swine and poultry.
