Meiosis I.

A pair of homologous chromosomes have what in common?
They have the same genes for the same traits.

Give one advantage of external fertilization and one advantage of internal fertilization.
(External: To compensate with the low survival rate, there are usually more offspring)[Internal: More protected due to having a method of protection from the parent.]

Joe bets Tony $100 that he can predict the score of the football game before it starts. Tony agrees but loses the bet. What was the score Joe bet?
Joe said the score would be 0-0 and he was right. 'Before' any football game starts the score is always 0-0.

Why would an organism want haploids in gametes rather than diploids?
So it can fuse with another gamete of a different gender to form a diploid zygote, allowing for greater genetic diversity.

A black dog stands in the middle of an intersection in a town. None of the street lights are working due to a power failure caused by a storm at night. A car with two broken headlights drives towards the dog but turns in time to avoid hitting him. How could the driver have seen the dog in time?
Who said this happened during the night? Actually, just name the formula for two gametes becoming 1 zygote you'll get triple points :D
