Abstract

Relations were defined between the values of reproductive traits of females (easiness and effectiveness of matings, reproduction maturity age, littering date, length of littering interval, number of pups born and reared in litter and pup losses during rearing) in successive reproduction seasons, considering polymorphic forms (2n = 50, 49 or 48), caused by Robertsonian translocation, of karyotype of arctic fox females. The type of vagina mucus resistiveness curve in females during oestrus in successive reproduction seasons was additionally examined. Repeatability indexes of reproduction traitsof females were low (0.191 - number of matings, 0.215 - number of pups born, 0.246 - number of pups reared, 0.248 - littering date, 0.277 - length oflittering interval) and medium (0.434 - pup losses, 0.487 - type of vaginamucus resistiveness curve). The frequency of polymorphic karyotype forms in analysed animals differed from its average values on other farms and reached: 10.6% (2n = 48), 38.2% (2n = 49) and 51.2% (2n = 50). Females with fusion karyotype (2n = 48 and 2n = 49) were characterized by better reproductive performance, especially by better fecundity and lower pup losses.
