Explain how the independent alignment of homologs, and also crossing-over during the first meiotic division, each contribute to
BartSMP [9]

Answer: Homologous chromosomes are randomly distributed to daughter cells, this means different chromosomes segregate independently of each other. And they exchange segments of DNA during crossing over. This recombination creates genetic diversity because genes from each parent are exchanged.

Explanation:

Meiosis is a type of cell division that produces gamete cells, which are sex cells (egg and sperm)

Chromosomes that form a pair and are found together are called homologous chromosomes, and they are inherited from each parent. During prophase of meiosis I, the homologous chromosomes exchange segments of DNA in a process called crossing over. This recombination creates genetic diversity because genes from each parent are exchanged. <u>It results in new combinations of genes on each chromosome.</u>

After that, during the anaphase of meiosis I, the two chromosomes line up on the equatorial plane of the cell. Then, they are separated and each will go to a new daughter cell. So homologous chromosomes are randomly distributed to daughter cells, <u>this means different chromosomes segregate independently of each other.</u>

What does it mean if a population is in Hardy-Weinberg equilibrium? Be specific.
Andrej [43]

Answer:

The Hardy-Weinberg law states that in a sufficiently large population, in which matings occur randomly and that is not subject to mutation, selection or migration, gene and genotypic free frequencies are kept constant from one generation to another, once a state of equilibrium has been reached, which in autosomal loci is reached after one generation.

It is said that a population is in equilibrium when the alleles of the polymorphic systems maintain their frequency in the population throughout the generations.

Where does transcription take place in the cell
bixtya [17]

In a prokaryotic cell, transcription and translation are coupled; that is, translation begins while the mRNA is still being synthesized. In a eukaryotic cell, transcription occurs in the nucleus, and translation occurs in the cytoplasm.
