The government protects intellectual property rights by enforcing patents on new pharmaceutical drugs. Suppose the government,

AveGali [126]

<h2>The correct answer is: Suffering loss.</h2>

Explanation:

Intellectual Property Rights are certain legal laws framed by the government of a country to ensure that the formulation, procedure of synthesis and monopoly of production of certain novel commodities remain with the inventor or discoverer of the commodities in form of patents.
According to the question, the legalization of the production of a particular pharmaceutical drug solely by the company Merck through patents prevents other companies from producing the same drug by copying the formulation of the drug from Merck.
Hence, the Merck company gets the monopolistic control on the production of the particular pharmaceutical drug and it can determine the price of the drugs as per not only its research and development costs but also as per its profit margin.
This is because Merck lacks any competitor in the pharmaceutical market as far as the particular pharmaceutical drug is concerned, who could produce and sell the drug at reduced prices.
Hence, the price of the pharmaceutical drug would be high causing the consumers to pay more and suffer losses for consuming the drug.

A female fly that has miniature wings and sepia eyes is crossed with a male that has normal wings and is homozygous for red eyes

Eduardwww [97]

Answer and Explanation:

The gene that expresses the size of the wing is X-linked. The dominant allele expresses long wings, XM, while the recessive allele expresses miniature wings, Xm.

The gene that expresses the color of the eyes is autosomal. The dominant allele expresses red color, S, and the recessive allele expresses sepia color, s.

A female fly that has miniature wings and sepia eyes (XmXm ss) is crossed with a male that has normal wings and is homozygous for red eyes (XMY SS).

The F1 are intercrossed to produce the F2.

F1) 1/2 or 50% of the progeny are females and the other 1/2 or 50% are males

100% of the females (1/2 or 50% of the progeny) are long-winged and red-eyed

100% of the males (1/2 or 50% of the progeny) are miniature.winged and red-eyed.

F2) 8/16=4/8=1/2 or 50% of the progeny are females and the other 1/2 or 50% are males

Females (8/16):

3/8 of the females are long-winged and red-eyed, XMX- S-

1/8 of the females are long-winged and sepia-eyed, XMX- ss

3/8 of the females are miniature-winged and red-eyed, XmXm S-

1/8 of the females are miniature-winged and sepia-eyed, XmXm ss

Males (8/16):

3/8 of the males are long-winged and red-eyed, XMY S-

1/8 of the males are long-winged and sepia-eyed, XMY ss

3/8 of the males are miniature-winged and red-eyed, XmY S-

1/8 of the males are miniature-winged and sepia-eyed, XmY ss

Note: The symbol "-" means that in its place might be a recessive allele or a dominant allele. For example, S- means that it might be SS or Ss.
