emmasim [6.3K]

Answer:

Following are the answer to the given points:

Explanation:

  • Unlinked - Nonrecombinant progeny (50%), recombinant progeny (50%)
  • Fully related genetics - 100% non-recombining genetic progeny (parental)
  • Incomplete connection of genes > 50% non-recombinant progeny < 50% crossover offspring. Connected genes

Mendel had established some essential concepts concerning inherited mechanisms such as the patterns of transmission of genes to offspring depending on their chromosomal placements. This same notion of linkage was offered to describe the pattern of the legacy of alleles on its chromosomal position.

Two different chromosomes have specific isoforms – for example, A and B which have two different features. As just a result, 50 percent of gametes are parental throughout type AB, and the other 50 percent of a recombinant in zygotes are quasi (aB & Ab) and 50 percent of the progenies that outcome from this mixture of gametes, therefore, are nonrecombinant in 50% and the cloned in 50 percent of the genetic makeup AaBb.

With two fully linked genes, e.g they exist on the very same chromosome and no cross-over occurs, all gametes are similar to parent types (AB and ab), like they do not split themself nor are diverse and culturally produced (nonrecombinants).

Which of the following are true? Select all that apply.
Bess [88]

Answer:

A. Renin levels increase with poor kidney perfusion

D. Nephrotoxic drugs are a cause of intrarenal failure.

Explanation:

Renin is produced in the kidney for angiotensin aldosterone hormonal system and it is helpful in maintaining the blood pressure and other metabolic activities. However when the renin level is high then it means the kidney has a perfusion issue .

Nephrons are kidney cells. When a drug which is toxic to them gets into the body system then it affects the kidney and may cause kidney failure.
