Your answer would most likely be letter
B. Biosphere
Answer:
35%
Explanation:
If two genes are 30 map units apart, 30% of the produced gametes will be recombinant.
A mating between an individual homozygous dominant for both traits (AB/AB) and one homozygous recessive for both traits (ab/ab) is conducted.
The F1 will be heterozygous for both genes: AB/ab.
The F1 progeny is then test-crossed to a homozygous recessive individual:
<h3>AB/ab X ab/ab</h3>
<u>The possible offspring will be:</u>
- Parental (70%): AB/ab and ab/ab
- Recombinant (30%): Ab/ab and aB/ab
Since 30% of all the gametes produced by the F1 individual will be recombinant, 70% will be parental. As there are two types of parental gametes, each of them will have a frequency of 35%.
<u>The offspring that will have a dominant phenotype for both traits has the genotype AB/ab with a proportion of 35%.</u>
Answer:
A .They result in sudden gene frequency changes.

Answer:
After mitosis is over, each of the daughter cells continues its separate life.
Explanation:
One or both can be started or continued through differentiation, ie. processes that give different cells special structures and functions. A cell destined to become a nerve cell moves in one way of differentiation, and a cell destined to be a muscle cell moves in another.
A variation of this mechanism involves a special type of cell called a stem cell. The stem cell divides by mitosis, whereby one daughter cell remains the stem cell and continues to divide again and again, while the other difference in certain cell peaks is determined in the tissues.
Answer:
(d) None of the above
Explanation:
The pH of your stomach must be highly acidic, because the optimum pH for pepsin, the chief stomach enzyme, is 1.5.
(a) and (b) are wrong, because both conditions are basic.
(c) is wrong, because pH 7 is neutral.
