Head moulding. Although, head moulding is common in any vaginal delivery, for a primigravid, which is having a child for the first time, is much more significant. The bones of a neonate are soft, flexible, and present gaps between them. These gaps and softness of the bones allow the moulding of the head when going through the vaginal canal. Being the first birth the vaginal canal is tighter and does not dilactate so well leading to a more significant head moulding.
Retrotransposons are class of transposons that contain long terminal repeats and code for an enzyme that synthesize DNA using an RNA template. It is found in all eukaryotes but absent in prokaryotes. About 42% of human genome is made up of retrotransposons. They are particularly abundant in plants, in maize 49-70% genome is made up of retrotransposons.
Answer:
QTL or Quantitative Trait locus
Explanation:
QTL or Quantitative Trait locus are chromosome sequences in which multiple genes contribute to a quantitative trait.
QLT is a locus that correlates with variation of quantitative trait in the phenotype of the population of an organism. It is an statistical method that links two type of information phenotypic and genotypic data in an attempt to explain the genetic variation in complex trait.
Density = mass/volume
X = 10/50
