Are stretch marks hereditary?

My dad doesn't have any stretch marks but my mum has them all over.. i think i have been cursed with my mums skin (i have stretch marks due to growth spurts, weight gain, muscle gain etc) so i look like a zombie.. My sister doesn't have any stretch marks (not even one!).. how come she doesn't have any and i do? (oh and she has also put on alot of weight while she was pregnant but still no stretch marks anywhere?)... it makes me so upset
