Allele: a version of one gene
Example: curly wing allele = A
Example: straight wing allele = a
“Homo” = Same
Homozygous: having identical alleles or versions of a gene for a t
Example: Homozygous Dominant (AA)
Example: Homozygous Recessive (aa)
“Hetero” = Different
Heterozygous: having different alleles or versions of a gene for a
Example: Heterozygous (Aa)

2. Read introduction and answer pre-lab questions
Pg 2-7
Pg 2-8
Investigation: Sexual Reproduction
1. Each partner will get a nucleus (plastic

cup) with two chromosomes (popsicle
sticks).
2. Close your eyes and randomly pick
one chromosome to pass down to your
offspring.
Male
Nucleus
Female

3. Record the genotype and phenotype
on your handout.
4. Add the traits to your fruit fly cut out
and place on wall next to similar flies.
5. Repeat until you have data for 4

Investigation: Asexual Reproduction
1. Close your eyes and select both
chromosomes from the female’s nucleus and
place them in the offspring nucleus.
3. Record the genotype and phenotype on
your handout.
Female

Investigation: Conclusion
Answer the questions below using
complete sentences.
Conclusion Question
1) Compare the offspring made by
sexual reproduction and asexual
reproduction.
2) Explain why the offspring made by
sexual reproduction differ from
asexual reproduction.
3) Imagine a virus infects both
populations of offspring and kills only
red eyed flies. Which population of
offspring is most likely to survive: the
population of sexually or asexually
