Genetics for Management

摘要: Publisher Summary This chapter discusses the genetics of management, which helps in designing strategies to protect human impacted marine mammals. The advantage genetic analyses is that data are easier collect and few constraints put on quality a sample or its origin. DNA relatively tough molecule, adequate samples can be obtained from tiny amounts variety tissues such as skin, blood bloodstains, hair follicles, placenta, excrement, baleen, modern ancient bone, some circumstances, formalin-preserved tissues. For instance, mtDNA ca . 1000-year-old bowhead whale ( Balaena mysticetus ) bones have been obtained. More recent historical bone baleen St. Lawrence Island Bering Sea used for both SNP analysis. Management-oriented studies use primarily (1) genotypes microsatellite loci within 3×10 9 so base pairs (bp) mammalian nuclear genome (2) sequence portion 1.6×10 4 bp mitochondrial genome; subsequence also known haplotype. Mitochondrial (mt) multicopy, circular, cytoplasmic mammals inherited intact mother. In contrast, microsatellites part biparentally.
