Assuming no crossing over between the gene in question and the centromere, during what phase of meiosis do alleles segregate?
choli [55]

Answer:

During Anaphase stage

Explanation:

Meiosis is the type of cell division employed during gamete formation when each resulting gamete (daughter cell) has their chromosomal number reduced by half. Meiosis occurs in a two step division; Meiosis I and II. Meiosis I involves the separation of homologous chromosomes (similar but non-identical chromosomes received from each parent) while Meiosis II involves separation of sister chromatids (replicated chromosomes).

Alleles are present on the chromosomes which segregate or separate during the anaphase stage. Alleles received from each parent are separated in Anaphase I of meiosis I, which the identical replicated alleles are separated in anaphase of meiosis II.

Reika [66]

Answer:

An independent variable

Explanation:

An experiment consists of two variables viz: independent and dependent variable. Independent variable is the variable that the experimenter controls in order to influence or effect a change in the measurable variable called dependent variable. As the name suggests, the dependent variable is dependent on the independent variable.

For example, a scientist is trying to conduct an experiment on how the caffeine level in different types of drink affects the time of sleep in individuals. The independent variable in this experiment is the TYPE OF DRINKS because it is the variable controlled by the experimenter in order to influence the time of sleep (measurable outcome).
