Two individuals produce offspring with a combination of genes from both parents by fertilization
a process that produces haploid gametes (i.e. egg and sperm) to maintain the correct number of chromosomes
What is the advantage of sexual reproduction?
Increases genetic variability (produces genetically unique offspring)
(This is more advantageous in fluctuating environments, i.e. environments that change a lot)
What does it mean to say that gametes are haploid?
They have half the number of chromosomes of that organism.
How many chromosomes does a human gamete have?
used by sperm to move
Is an egg much larger than sperm, or sperm much larger than egg?
Egg is much larger than sperm.
What does it mean to say that an egg is non-motile?
It can't move on its own.
Differences between sperm and egg:
Egg is much larger
Sperm moves on its own using flagellum; egg cannot move on its own
