Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

Expert Solution

Step 1: Introduction

( You have posted more than 1 question, as per guidelines I am solving first question below. Please post remaining question separately. )

Structure of a chromosome : A typical chromosome has centromere and 1/ 2 arms. Chromonema which is coiled structure is present in ground substance called as matrix.

Chromatids are 2 subunits in chromosome which gets separated in anaphase. Telomere is terminal part of each arm of chromosome.

One chromosome will have 2 telomeres. Centromere is a point of attachment for spindle fibres in metaphase and also called as primary constriction.

Draw the stages (prophase, metaphase, anaphase and telophase with cytokinesis) of the two cell divisions in the corresponding boxes of Table 1. No need to include prometaphase. One box is to one stage. For each stage, draw clearly the appearance and configuration of the cell(s) and the chromosomes. Inspect and refer to slides 10 to 11 of the Cell Division PPT for mitosis and slides 14 and 17 for meiosis. Make sure that when the pictures are zoomed in, they will still be clear.
