Because females produce eggs compared to the sperm that males produce, females choose a male with the best , or the ability to produce surviving young.

limited number of eggs; limitless sperm

best genetic quality

Explanation:

Females generally produce a limited amount of eggs. This is as a result of the structure and arrangement of female reproductive organs. On the other hand, males produce an unlimited amount of sperms. This is also a result of the reproductive organs in males. However, females must choose the males with the best genetic quality to produce surviving offspring.

less eggs

Millions of sperm

Viability

Explanation:

During fertilization,the female gametes known as the ovum produces and releases eggs that will wait for spermatozoa from the male to fertilise them.during copulation,millions of sperms are produced and release but it is only the viable sperm with higher speed that are able to get to the viable eggs.viable eggs can stay alive for 1-2 days after which they die off .those fertilize later form foetus in a complex process known as reproductive process.
