Females have two copies of the X chromosome, while males have one X and one Y chromosome. The 22 autosomes are numbered by size. The other two chromosomes, X and Y, are the sex chromosomes.

In the book Carrots Love Tomatoes it says Don't plant tomatoes near corn because the tomato and corn earworm are identical..
Best Answer: That depends on several variables, not the least of which is the type of corn that you planted. Feed corn, for example, ripens later than sweet corn. If you plant iearly n April the corn should be ripe about now. It takes about six months but the weather plays a large part in the equation. Corn doesn't start to grow well until the days (and the nights) are warmer, so if you get a cold, wet spring, or the summer isn't as warm as usual, the harvest will be late.
