A RICH AND VARIED GENE POOL
Homosexuality is basically
genetic
 Effects of future genetic
manipulation

Will NOT force genes for
homosexuality to dissipate
 Stay the same or increase at
little


Technology will one day
allow homosexual partners to
have children that are
genetically theirs

BISEXUALITY

2 Features
High ejaculation rate
 Multiple partners


Male


~5% of men are bisexual
More male partners = more
female partners
Will inseminate more females
than heterosexual men
Adolescent homosexual
interactions gives experience
Fewer sperm
Homosexuality is typically
bisexuality (even among
animals)

BISEXUALITY

Female


not unique to the human species
more likely than heterosexual women to have
simultaneous or immediately consecutive male
partners
Trend for bisexual women to have children earlier,
but fewer overall
Less than 1% of women are exclusively homosexual;
80% are bisexual
Exhibit behaviors later in life
Same overall reproductive rate as heterosexual
women

HOMOSEXUALITY
Male




Not unique to humans
Nearly 6% of men show
homosexual behavior
during their lifetime
Inheritance more often
via mother [some genes
on X]
Environmental factors
Necessary experiences
bring out genetic
inclination
 Seduction / force
Female

Only 1% exclusively
homosexual (nonreproductive)
Less than 1% exclusively
homosexual
Sexual knowledge and
experience
Fewer homosexual women
than men

3% women vs. 6% men
More likely to have
concurrent male partners,
but fewer partners overall
than men
More likely to have longerlasting monogamous
relationships

“So why, if bisexuals reproduce
just as successfully as
heterosexuals, are only 6 percent
of men and 3 percent of women
homosexual in modern industrial
societies?”

TAKE OVER

Risks/Dangers
1) injury/death by members
of society due to homophobia
 2) STDs


If these risks were
removed…
There would be no restraints
on the gene
 Reproductive benefits would
increase the population
 “Everybody would be
bisexual”


WHAT WILL SEX IN THE FUTURE
LOOK LIKE FOR HOMOSEXUALS AND
BISEXUALS ?...

Gamete manufacture
2 Women:
1 woman donates host egg
 Nucleus of other woman’s
egg injected in to host egg
 Only have girls (XX)


2 Men:
Need egg donor and
surrogate
 Nucleus from egg replaced
with nucleus 1 man’s
sperm
 Whole sperm from man 2
injected into egg
 Either boy or girl


THE FUTURE
“In the twenty-first century, infertility will have
no meaning even for people who are exclusive
homosexuals and produce no gametes”
 Even with risks of disease removed, genes for
homosexuality will not take over the gene pool
 Choice of parents / individuals will keep us safe

DISCUSSION QUESTIONS

3.
Did any of the information presented today
surprise you?
In your experience, has the perception of
homosexual behavior changed? Why or why not?
The authors proposed that technology will
eliminate infertility. Do you believe this could
occur? What consequences could this have on
the gene pool?
