Sexual reproduction involves the combining and mixing of genetic traits: specialized cells known as gametes combine to form offspring that inherit traits from each parent.

Gametes can be identical in form and function (known as isogamy), but in many cases an asymmetry has evolved such that two sex-specific types of gametes (heterogametes) exist (known as anisogamy).

While cake is baking, combine the pineapple,1 cup of sugar in a saucepan, and bring to a boil over medium heat stirring constantly. Remove cake from oven and using a fork, pierce holes into cake.

I was watching Love and Death (1975) the other night when Sonja (Diane Keaton) turned to Boris Grushenko (Woody Allen) and implored, "Boris, please! " "Yes," said Boris in a classic Woody comeback, "but as empty experiences go, it's one of the best." See Also: Things we should never do again after turning 50. Over breakfast the next morning with two close friends, George (57) and Carol (64), I sounded them out on the issue: "Can you come up with 10 things that are better than sex?

Or might something else have topped it when we weren't looking?

Which led me to another notion: Is sex still one of the best experiences around? By the weekend, my list of "Things Better than Sex" had grown to 50. Bumping into someone you haven't seen in years and hearing, "You haven't changed a bit! Knowing that in ways no one else can see, you have changed — more than a bit, and all for the better 32.

Remembering the best sex you ever had Do you have something to add to the list? Sex comprises the arrangements that enable sexual reproduction, and has evolved alongside the reproduction system, starting with similar gametes (isogamy) and progressing to systems that have different gamete types, such as those involving a large female gamete (ovum) and a small male gamete (sperm).In complex organisms, the sex organs are the parts that are involved in the production and exchange of gametes in sexual reproduction.Some of the many plausible theories include: that sex creates variation among offspring, sex helps in the spread of advantageous traits, that sex helps in the removal of disadvantageous traits, and that sex facilitates repair of germ-line DNA.Sexual reproduction is a process specific to eukaryotes, organisms whose cells contain a nucleus and mitochondria.
