I think the answer is B, that most amino acids are encoded by more than one codon.
<span>The bottleneck effect is the cause of the sudden shift in the genetic information of the population. Due to the landslide, suddenly high number of the members of the main population died, and this caused genetic drift for reducing the variation in the existing generation, which is now widely different from the original one.</span><span />
The answer is Fossilized Amber.
Answer:
D. The first division will reduce the number of chromosomes by half for each daughter cell, and the second division will move single chromatids to each daughter cell.
Explanation:
Gametes are formed by meiosis in diploid gamete mother cells. During gamete formation, the gamete mother cell in the yeast would undergo meiosis I. During first division (meiosis-I), the process of crossing over during prophase-I creates genetic variations and movement of homologous chromosomes to the opposite poles during anaphase-I reduces the chromosome number to half in each daughter cell.
Two daughter cells are formed by the end of meiosis-I each of which enters meiosis-II. Splitting of centromere and separation of sister chromatids during anaphase-II of meiosis-II results in the movement of single chromatids to the opposite poles of the cells.
