Litter size of large white pig
WebIn biology, a species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction.It is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity.Other ways of defining species include their karyotype, … Web9 dec. 2015 · In this study, we focus on litter size and its variability in a Large White pig population. Many studies have reported single nucleotide polymorphisms (SNP) and QTL for the mean litter size of a genotype, and such QTL have been found on all Sus scrofa chromosomes (SSC) except SSC11, SSCX and SSCY (PigQTLdb, ).
