Why are Four sperm formed for every one egg?

millions of sperms are formed for every one egg.
But the answer may be the egg is big and the sperm is smaller.

4 sperm are formed during meiosis while only 1 egg is fully functional. Although 4 haploid cells are produced, 3 will die and become polar bodies.

I was thinking of a menstrual cycle. while 1 egg is produced in about a month, millions of sperms are produced.

Probably, mithril... I was going to ask that 2
About that last question. If I were to pick one it would be bacteria, because it can live in a lot of places where humans can not. But, in my opinion you can not compare a domain(Bacteria) to a species(Homo sapiens). Anyway, i guess your answer will do.
Except for the one with s1 and s2 they are all fine

on the worksheet she gave us, it says S1 and S2, i guess the teacher made a mistake.... it probobaly was supposed to be G1 and G2 ..... so in G1 it would still have 40 chromosomes and in G2 it would have 80, right?

And for the Monohybrid cross, Wouldnt that involve two genes, Because arent you crossing one gene with another gene, total of two genes involved

It's the same gene, unless it's a trick question, then you should answer as 1 pair of homologous genes.
From g2-the m-phase, the chromosomes are doubled.
