Sexual Reproduction
• Two organism are necessary for
reproduction (Mom and Dad)
• Male sex cell (sperm) and female
sex cell (egg) unite to make a
zygote.
Sexual Reproduction
• Offspring contains traits from both
parents (similar to parents but not
identical)
• They receive 50 percent of the
genes from mom and 50 percent
from dad.
