These chromosomes are present in equal pairs and they can be defined as thread-like structures which are found inside the nucleus of every cell.Complete answer:A chromosome is microscopic and is present in each cell’s nucleus, and in the form of thread-like structures.Structurally, each chromosome is composed of DNA that is tightly coiled around special proteins called histones.Option A: In humans, there are 23 pairs of chromosomes and not autosomes. Therefore, this is the incorrect option.Option B: All living organisms have chromosomes. Humans have 23 pairs of chromosomes.Out of these, 22 pairs are called the autosomes – these are similar in males and females. Therefore, this is the incorrect option.The 23rd pair of chromosomes (sex chromosome) called “allosomes” differ between the sexes.Males have one “X” and one “Y” (44A+ XY) chromosome, while females have two copies of the “X” (44A + XX) chromosome.Option C: In humans, 46 chromosomes are found which is 23 pairs of chromosomes and not allosomes. Therefore, this is the incorrect option.Option D:In humans, there are 22 pairs of autosomes, but not 44 pairs. Therefore, this is the incorrect option.Thus, the correct option is (B) 22.Note:In humans, each of the parents contributes one of their sex chromosomes to their offspring, so that the child gets half of its chromosomes from the mother and half from the father. A chromosome houses DNA in a cell, and contains elements necessary for processes like - segregation and replication.Recently Updated PagesBasicity of sulphurous acid and sulphuric acid areMaster Class 12 Business Studies: Engaging Questions & Answers for SuccessMaster Class 12 Economics: Engaging Questions & Answers for SuccessMaster Class 12 English: Engaging Questions & Answers for SuccessMaster Class 12 Maths: Engaging Questions & Answers for SuccessMaster Class 12 Social Science: Engaging Questions & Answers for SuccessBasicity of sulphurous acid and sulphuric acid areMaster Class 12 Business Studies: Engaging Questions & Answers for SuccessMaster Class 12 Economics: Engaging Questions & Answers for SuccessMaster Class 12 English: Engaging Questions & Answers for SuccessMaster Class 12 Maths: Engaging Questions & Answers for SuccessMaster Class 12 Social Science: Engaging Questions & Answers for Success
