A diploid organism is heterozygous for 4 | Class 12 Biology Chapter Principles of Inheritance and Variation, Principles of Inheritance and Variation NCERT Solutions

Question: Why are living organisms classified?
Answer:

A large variety of plants, animals, and microbes found on earth and they differ in size, shape, colour, habitat, and many other characteristics. So, studying each of them is impossible. Therefore, scientists have devised mechanisms to classify all living organisms on certain rules and principles that allow identification, nomenclature, and finally classification of an organism.

 

For example, based on presence of three pairs of legs and 2 pairs of wings, an organism is identified as an insect, it will be given a scientific name and then grouped with other similar organisms. Thus, various groups or taxon include organisms based on their similarity and differences.

 

Therefore, the biological classification helps in revealing the relationship between various organisms. It also helps in making study of organisms easy and organized.

Formula for calculating no. of gametes is 2 to the power n, where n is no of the genes. Here heterozygous for four loci means, four diff genes as alleles for a gene are present on same locus on the homologois pair. So the answer is 2^4=16

So answer is 8 or 16? If 16 please explain I didn’t understand

formula is 2^n.where n=no. of loci .therefore,2^4=16 types of gametes

If a diploid organism is homozygous for two loci then the gametes formed will be say A B C D respectively.Since it\'s a diploid organism the number of gametes will be 2×n. Therefore the number of gametes will be 2×4=8
