A whole-genome scan for quantitative trait loci affecting teat number in pigs.
A whole-genome scan was conducted using 132 microsatellite markers to identify chromosomal regions that have an effect on teat number. For this purpose, an experimental cross between Chinese Meishan pigs and five commercial Dutch pig lines was used. Linkage analyses were performed using interval mapping by regression under line cross models including a test for imprinting effects. The whole-gen...
متن کاملIdentification of quantitative trait loci affecting reproduction in pigs.
The objective of this research was to identify chromosomal regions harboring QTL affecting reproduction in pigs. A three-generation resource population was developed by crossing low-indexing pigs from a randomly selected control line (C) with high-indexing pigs of a line selected for increased index of ovulation rate and embryonic survival (I). Differences between Lines I and C at Generation 10...
متن کاملEvidence for quantitative trait loci affecting ovulation rate in pigs.
Fifty-five microsatellite markers were scored in an F2 population of pigs (n = 114 females) developed at the University of Nebraska. The population was produced by crossing a line previously selected for 10 generations using an index of ovulation rate and embryonal survival and a line selected at random. The lines were from a common base population and differed by 6.7 ovulations and 3.1 fetuses...
متن کاملMapping of Quantitative Trait Loci (qtl)
What is a QTL? A Quantitative Trait Locus a region of the genome that is associated with an effect on a quantitative trait. Conceptually, a QTL can be a single gene, or it may be a cluster of linked genes that affect the trait. Using the methods for QTL detection to be discussed below, it is not possible to resolve the difference, and use the term “locus” to refer to a chromosomal region. Are Q...
متن کاملDetection of quantitative trait loci for teat number and female reproductive traits in Meishan × Large White F2 pigs.
A quantitative trait locus (QTL) analysis of female reproductive data from a three-generation experimental cross between Meishan (MS) and Large White (LW) pig breeds is presented. Six F1 boars and 23 F1 sows, progeny of six LW boars and six MS sows, produced 573 F2 females and 530 F2 males. Six traits, i.e. teat number (TN), age at puberty (AP), ovulation rate (OR), weight at mating (WTM), numb...
