Explain why human offifuing resemble their parents but are not identical to them.

Expert Solution & Answer

Summary Introduction

To explain: Why human offspring are similar to their parents but they are not identical to them.

Introduction: Heredity is the process of the transmission of traits or heritable information to the next generation in the form of DNA. Humans reproduce sexually. During sexual reproduction, the genetic information from both the parents gives a unique gene combination in the offspring. The offspring resemble their parents but are somewhat different in their genetic makeup, which explains the genetic variation.

Explanation of Solution

Humans undergo sexual reproduction and inherit one chromosome of each homologous pair of chromosomes from each parent. Each somatic cell in humans consists of 46 chromosomes, which are two sets of 23 chromosomes each (maternal and paternal set).

During sexual reproduction, most of the variation arises during fertilization and meiosis. During meiosis, the homologous chromosomes randomly align with their homologs at metaphase I. According to the law of independent assortment of chromosomes, each daughter cell shows either maternal or paternal chromosome combinations. Thus, there is a 50% chance that the offspring gets maternal or paternal chromosomes or a combination of both. Secondly, crossing over forms the recombinant chromosomes that consist of a unique combination of genes in the offspring. The next aspect is random fertilization, which could be between any male gamete and female gamete. These factors relate to the fact that the offspring resemble their parents but are not exactly identical.

A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.

With reference to their absorption spectra of the oxy haemoglobin intact line) and deoxyhemoglobin (broken line) shown in Figure 2 below, how would you best explain the reason why there are differences in the major peaks of the spectra? Figure 2. SPECTRA OF OXYGENATED AND DEOXYGENATED HAEMOGLOBIN OBTAINED WITH THE RECORDING SPECTROPHOTOMETER 1.4 Abs < 0.8 06 0.4 400 420 440 460 480 500 520 540 560 580 600 nm 1. The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobin
