Every germ cell will take one chromosome from each pair and these may be of either maternal or paternal origin. When two germ cells combine, they will restore the normal number of chromosomes in the progeny, ensuring the stability of the DNA of the species.
Such a mechanism of inheritance is explained in _______________.
1
mutation in species
2
variation in chromosomal number
3
speciation of organisms
4
the results of the Mendel's experiments
