  • This way, each parent contributes half of the genetic information for their child. (primaryimmune.org)
  • Dr Takeuchi went on to explain that the oyster's genome is made up of 14 pairs of chromosomes, one set inherited from each parent. (thefishsite.com)
  • This is the way in which one half of the genetic information comes from each parent. (poodleclubofamerica.org)
Congenital1
  • In the literature, congenital malformations are often associated with genetic diseases because they both tend to present during pregnancy, at birth or in early childhood. (who.int)
Disease1
  • DNA provides important information on genetic or hereditary patterns of disease or risk of disease. (cdc.gov)
Cancer3

Genome4
  • Genetic researchers from the Okinawa Institute of Science and Technology (OIST) have mapped the genome of pearl oyster and found that preserving genetic diversity could boost immunity in broodstocks while improving yields. (thefishsite.com)
  • Now, researchers from the Okinawa Institute of Science and Technology (OIST), in collaboration with a number of other research institutes including K MIKIMOTO & CO, LTＤ, Pearl Research Institute and Japan Fisheries Research and Education Agency, have constructed a high-quality, chromosome-scale genome of pearl oysters, which they hope can be used to find resilient strains. (thefishsite.com)
  • They continued genome sequencing to establish a higher quality, chromosome-scale genome assembly. (thefishsite.com)
  • Traditionally, when a genome is sequenced, the researchers merge the pair of chromosomes together. (thefishsite.com)
Autosomal1
Sequences2
  • Chromosome 17p sequences were usually lost only in carcinomas (75 percent). (nih.gov)
  • Genetic sequences of the bases are read in groups of three (called a triplet), with a possibility of 64 configurations or "words" in which to code information. (cdc.gov)
Counselor2
  • Talk to your healthcare provider or a genetic counselor to learn more about uniparental disomy. (chkd.org)
  • You may want to talk to a genetic counselor before or after the test. (healthwise.net)
Researchers3
  • Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. (news-medical.net)
  • Researchers discuss the role of oxidative stress in genetic conditions. (news-medical.net)
  • The researchers found that after three consecutive inbreeding cycles, the genetic diversity was significantly reduced. (thefishsite.com)

Copy3
  • Extreme chromosome 17 copy number instability is a prognostic factor in patients with gastroesophageal adenocarcinoma: A retrospective cohort study. (umassmed.edu)
  • This means 1 copy from the genetic mother, and the other copy from the genetic father. (chkd.org)
  • A clone is an organism that is a genetic copy of an existing one. (who.int)
Prevalence1
  • The higher prevalence of genetic diseases in particular communities may, however, be due to some social or cultural factors. (who.int)
Biological father1
  • Remember that, just like you, your biological father inherited two sets of 23 chromosomes from each of his parents. (helix.com)
Allele1
  • This means that males, who have only one X chromosome, are more likely to express the recessive allele if they inherit it. (proprofs.com)
Traits2
  • In short, we all inherit a unique patchwork of traits from our ancestors-which is exactly why we all have a unique genetic ancestry. (helix.com)
  • In his evolutionary theory, he claimed that genetic traits can be acquired and passed down. (lu.se)
Total4
  • There are 23 pairs of chromosomes, for a total of 46. (mayoclinic.org)
  • This graph shows the total number of publications written about "Chromosomes, Human, Pair 17" by people in this website by year, and whether "Chromosomes, Human, Pair 17" was a major or minor topic of these publications. (umassmed.edu)
  • This "master plan" genetic material is packaged into 23 pairs of chromosomes, for 46 total chromosomes. (primaryimmune.org)
  • Since pearl oysters have 14 pairs of chromosomes, they have 28 in total. (thefishsite.com)
SNPs1
  • We focused on SNPs within or near TACR1/LOC105374811 (chromosome 2) and CTNNA3/DNAJC12 (chromosome 10). (cdc.gov)
Phenomena1
  • Physical growth is characterised by a sum of cellular, biological, biochemical and morphological phenomena, whose interaction is performed by a predetermined genetic plan, which is influenced by the environment 4,5 . (bvsalud.org)
