Chapter 15, Problem 11TYU
Summary Introduction
To analyze: Benefits of having similar segments on X and Y chromosomes.
Introduction: Humans are diploid organisms having 23 pairs of chromosomes out of which the last two, X and Y-chromosomes are known as sex chromosomes whereas the rest are known as autosomes. These sex chromosomes are passed on from parents to progeny as they carry the genes which are important for the development of traits and characteristics in the offspring. The females have both XX- chromosomes whereas the males have XY-chromosome.

Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
