of myocardial contractile cells is due to the Na+ ions. Sodium ions are essential
for regulation of blood and body fluids, communication of nerve impulses, heart

haploid (n) or triploid (3n)
Explanation:
If none of the chromosomes separate during meiosis, the resulting gametes will either lack chromosome or have diploid number (2n) of chromosome instead of a haploid number.
If an egg without chromosome (o) fertilizes a normal sperm (n), the resulting zygote will have haploid number (n) of chromosome.
If an egg with diploid number of chromosome (2n) fertilizes a normal sperm (n), the resulting zygote will be a triploid with 3n number of chromosome.
