Yes, it is true. answer : true
Answer: 1/64 would be normal
Explanation:
Let the woman phenotype be Yy, since a carrier is usually heterozygous;
Also let the husband phenotype be Yy
Then Yy seperate to yield two alleles "Y" and "y"
So, the cross of the two alleles:
"Y", "y" X "Y", "y"
F1 will be YY, Yy, Yy and yy
From the crossing,
- the normal phenotype are YY,
-the carriers are Yy, Yy
- while yy is recessive.
Since, the probability that one of their offspring is normal is 1/4; for three children, then 1/4 x 1/4 x 1/4 = 1/64
Thus, probability that all three children are normal is 1/64
- penicillin
- aluminum hydroxide
- insulin
- codeine
Answer:
- aluminum hydroxide
Explanation:
Aluminium hydroxide is an antacid gotten by synthesizing and separating the precipitate formed from the reaction between AlCl3 solution with NaOH solution. Aluminium hydroxide is a drug used in treating heartburn and acid indigestiion.
Penicillin, insulin and codeine are gotten from natural organic sources. Insulin is derived from an animal source. Codeine also is derived from organic compounds from plants. Penicillin is a metabolite of some species of Penicillium, which are micro-organisms.
