An individual that is homozygous dominant for type B blood and little finger shape mates with an individual that is heterozygous

gregori [183]

Answer:

Let "L" be the dominant allele for little finger shape and "l" be the recessive allele for the same.

It is given that a person is homozygous dominant for blood group B and little finger shape. Hence, the genotype would be $I^BI^B$ LL

The other person is heterozygous for blood group A and homozygous recessive for little finger shape. Hence, the genotype would be $I^Aill$

The type of gametes formed by the first parent would be $I^BL$ only.

The type of gametes formed by second parent would be $I^Al$ and il.

The cross is shown in the attached figure.

According to the cross, we get two phenotype:

offspring with blood group AB and dominant little finger shape, and
offspring with blood group group B and dominant little finger shape.
They are present in 4 : 4 = 1 : 1

According to the cross, we get two genotype:

$I^AI^BLl$
$I^BiLl$
They are also present in 4 : 4 = 1 : 1.

upper gastrointestinal scan

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. In upper GI series, the fluoroscopy allows radiologist to see movement of barium through esophagus, stomach, and duodenum as the person drinks.
