प्रश्न
Give the basic features of the mechanism of inheritance.
उत्तर
Genes present on the chromosomes control characters or traits. A gene controls a character and has two or more forms and one form may be dominant over the other. An individual has two similar or dissimilar forms of a gene controlling a trait, one inherited from each parent. The two forms of a gene separate during gamete formation so that each gamete has only one form. These two forms of a gene are brought together in the zygote when gametes fuse at the time of fertilisation.
