A) autosomes
B) allosomes
C) genome
D) karyotype
Correct Answer: B
Solution :
Sex chromosomes are also known as allosomes. These are the chromosomes that operate in the sex determining mechanism of a species. Two types of sex chromosomes are found X and Y both of these differ in shape, size, DNA content and sedimentation rate. In birds and lepidopteran, they are called Z and W. Autosomes are present in all somatic cells and are not related to sex determination. Genome refers to all the genes contained in a single set of chromosome, ie, in a haploid nucleus. Each plant through its reproductive cells contributes its genome to its offspring. Karyotype is denned as a number and structure of the chromosome in the nucleus of a cell. The karyotype is identical in all the diploid cells of an organism.
