What to do if I am facing side effects of the drugs?
Explanation:
Atopic dermatitis: It is the most common form of Eczema and appears as red itchy rash on cheeks, arms and legs. Mostly children suffer from it. It is a chronic condition and may be associated with Asthma and Hay fever.
Note: There is no definite treatment for it but different agents (drugs) along with precautions can alleviate the symptoms.
Pimecrolimus: It is an immunomodulating agent of calcinuerin inhibitor class used for the treatment of atopic dermatitis.
epistatic gene
Explanation:
Some genes mask the expression of other genes just as a fully dominant allele masks the expression of its recessive counterpart. A gene that masks the phenotypic effect of another gene is called an epistatic gene; the gene it subordinates is the hypostatic gene.
Answer: 25 of the chicks will be black
Explanation: Since the chickens are intermediate in colour, that is they are not black, they are heterozygous. Let B represent the allele for black colour and B represent the allele for blue colour, therefore the genotype of a chicken with an intermediate colour is Bb. A cross between two Bb chicken will produce 1 BB, 2 Bb and 1 bb chicks. 1 BB will manifest outwardly as black, 2Bb will manifest outwardly as intermediate colored while 1 bb will manifest outwardly as blue colored chicks.
Since one out of four chicks are black colored, if the two chicken produced 100 chicks, the number of chicks that will be black is 1/4 x 100 = 25. Therefore, 25 chicks out of 100 will be black.
