masya89 [10]3 years ago
6 0
Woman's genotype: ii
Husband's genotype: I^A i
-> possible husband's father genotypes are two I^B and I^B i
-> if husband's father has two I^B alleles, the husband will have one I^B allele present, which is not the case. So, there is i allele present. (can also infer that I^A comes from husband's mother)

Child's possible genotypes:
ii, ii, I^A i, I^A i
probability is 1/2

The _____________ is a fluoroscopic examination of the esophagus, stomach, and duodenum, involving oral administration of barium
Dmitry_Shevchenko [17]

Answer:

upper gastrointestinal scan

Explanation:

Upper gastrointestinal series is the radiographic examination of upper gastrointestinal tract. Esophagus, stomach and then duodenum are visible on the X-ray film by the use of the liquid suspension which may be barium or water-soluble contrast.

Fluoroscopy is used during upper GI series. A continuous beam of X-ray rays is passed through body part and is transmitted to the monitor so that body part and the motion of it can be seen in every detail. <u>In upper GI series, the fluoroscopy allows radiologist to see movement of barium through esophagus, stomach, and duodenum as the person drinks.</u>

How is polyploidy different than the mutation of one or two genes
lubasha [3.4K]

Answer:

<h2>Polyploidy is different than the mutation of one or two genes because mutation in one or two genes do not involve the whole set of chromosome as in polyploidy. </h2>

Explanation:

1. Polyploidy:  the condition in which a normally diploid cell or organism gain one ( triploid, 3N) , two ( tetraploid, 4N) or  more additional sets of chromosomes. Polyploidy arises as the result of total non-disjunction of chromosomes during metaphase of mitosis or meiosis, in which the chromosome are not separated during cell division.

2. Mutation: a mutation is a heritable change in the genetic material of an individual.

As given here, the mutation of one or two genes is differ than polyploidy because the polyploidy involves the whole set of chromosome white mutation can be occur in a small portion of chromosome, a single gene, two genes, or large number of genes.  

Polyploidy is different than the mutation of one or two genes because mutation in one or two genes do not involve the whole set of chromosome as in polyploidy.
