features of chromosomal Theory of inheritance_??

$\huge{{\mid{\fbox{\tt{ANSWER}}\mid}}}$

features of chromosomal theory of inheritance are as follows:

• Like the hereditary traits the chromosomes retain their number, structure and individuality throughout the life of an organism and from generation to generation. The two neither get lost nor mixed up. They behave as units.

• Both chromosomes as well as genes occur in pairs in the somatic or diploid cells. The two alleles of a gene pair are located on homologous sites on homologous chromosomes. Both chromosomes as well as genes segregate at the time of gamete formation such that only one of each pair is transmitted to a gamete.

• A gamete contains only one chromosome of a type and only one of the two alleles of a trait.

• The paired condition of both chromosomes as well as Mendelian factors is restored during fertilization.
