The correct answer is "applying cold compresses to the affected area".

Most of the people stang by a bee or wasp experience a localized reaction and only 3% of the people will exhibit an allergic reaction. The normal localized reaction includes reddening and swelling of the skin, along with a local itching and pain.

Although these reactions will probably start disappearing within a few hours, there are several things that the person could do to alleviate the pain and discomfort. The most important thing to do is to apply ice or cold compresses to the affected area, to reduce the body's inflammatory response.

Answer:

D. If all of the offspring are short-tailed, the unknown individual is the homozygous dominant genotype.

Explanation:

The short tail phenotype is completely dominant over the long tail phenotype. When a short tailed salamander with unknown genotype is crossed with a homozygous recessive long tailed salamander, the cross is called testcross. Lets assume that the allele "S" gives "short tail" phenotype while the allele "s" gives "long tail" phenotype.

If the "short tailed salamander" with unknown genotype is homozygous dominant (SS), the process of the testcross will express only dominant trait (cross 1). On the other hand, if the "short tailed salamander" with unknown genotype is heterozygous dominant (Ss), segregation of alleles during gamete formation would form two types of gametes (cross 2). The 50% progeny would express the "long tail" phenotype while rest 50% will express the "short tail" phenotype.
