What's the difference between ancestral and pedigree?

Ancestral


Definition:

  • (a.) Of, pertaining to, derived from, or possessed by, an ancestor or ancestors; as, an ancestral estate.

Example Sentences:

  • (15) Although most studies emphasise the similarity of the australopithecines to modern man, and suggest, therefore, that these creatures were bipedal tool-makers at least one form of which (Australopithecus africanus--"Homo habilis", "Homo africanus") was almost directly ancestral to man, a series of multivariate statistical studies of various postcranial fragments suggests other conclusions.
  • (16) The conservation of genomic organization, together with the high sequence homology, indicates that the mouse H+,K(+)-ATPase beta and Na+,K(+)-ATPase beta 2 subunit genes originated from a common ancestral gene.

  • (19) Similarities observed between these two genes with respect to both peptidic sequence and intron position strongly suggested that this locus originated from the duplication of an ancestral transcription unit.
  • (20) Our findings substantially increase the evidence indicative of a human-chimpanzee-gorilla clade with ancestral separations around 8 to 6 Myr ago.

Pedigree


Definition:

  • (n.) A line of ancestors; descent; lineage; genealogy; a register or record of a line of ancestors.
  • (n.) A record of the lineage or strain of an animal, as of a horse.

Example Sentences:

  • (1) Pedigree studies have suggested that there may be an inherited predisposition to many apparently nonfamilial colorectal cancers and a genetic model of tumorigenesis in common colorectal cancer has been proposed that includes the activation of dominantly acting oncogenes and the inactivation of growth suppressor genes.
  • (2) Several pedigrees have been reported in which defects of the insulin gene result in glucose intolerance or diabetes in affected members, but the role of insulin gene mutations in NIDDM is unknown.
  • (3) Another feature of TWINAN90 is the optional output of a pedigree file which can be read by the quantitative genetics package FISHER.
  • (4) ESD in conjunction with RB polymorphism would be useful in prenatal and presymptomatic diagnosis, as well as in carrier detection in informative pedigrees.
  • (5) This paper presents a FORTRAN IV subroutine to calculate inbreeding and kinship coefficients from pedigree information in a diploid population without self-fertilization.
  • (6) Histologic examination of one patient from each pedigree showed two characteristic findings in corneal epithelium; the previously designated "peculiar substance" in the cells, and the vacuolated homogeneous substance mostly within the cysts.
  • (7) While Elop has critics who say he did not fix Nokia or much of anything else in his long career in tech, others are likely to point to a pedigree that would also make him the favorite here.
  • (8) The pedigree analysis provided evidence of both a genetic effect (P less than 0.005) and an effect of increased dietary iron (P less than 0.005) on transferrin saturation and unsaturated iron-binding capacity.
  • (9) On the other hand, Sillence OI type I segregated with both COL1A1 (17 pedigrees) and COL1A2 (7 pedigrees).
  • (10) Using 166 pedigrees, reported in nine series available in the literature (including our own), we conclude that balanced insertion cannot entirely explain the familial data, even if we allow for a reduced viability of unbalanced gametes.
  • (11) To study the genetic influence on serum cholesterol levels and early coronary heart disease, 1,134 individuals were screened from 18 Utah pedigrees.
