How do organisms reproduce and transfer genes to their offspring?
Sexually or asexually and then genetic info is transferred to offspring.
Asexual results in offspring that are genetically identical. Sexual results in genetic variation.
They inherit 1/2 of their genes from each parent.
How do offspring produced by asexual reproduction and sexual reproduction compare?
Sexually or asexually and then genetic info is transferred to offspring.
Asexual results in offspring that are genetically identical. Sexual results in genetic variation.
They inherit 1/2 of their genes from each parent.
Why do different offspring of the same parent usually look different?
Sexually or asexually and then genetic info is transferred to offspring.
Asexual results in offspring that are genetically identical. Sexual results in genetic variation.
They inherit 1/2 of their genes from each parent.
All living things reproduce one of two ways: ________________ or ______________
Asexual, Living
Sexual, Non-living
Asexual, Sexual
Sexual, Germination
Reproductive process that only requires 1 parent
Asexual
Sexual
Offspring are genetically identical
Sexual
Asexual
Is the simplest form of reproduction.
Sexual

*What do you think is the benefit of reproducing asexually? Explain how asexual reproduction could give some animals an advantage.
Sexually or asexually and then genetic info is transferred to offspring.
Asexual results in offspring that are genetically identical. Sexual results in genetic variation.
They inherit 1/2 of their genes from each parent.
Can produce w/o a mate, can reproduce many times in a small amount of time
Produces a variety of traits

Variations
Gene
______________= Differences in the traits
Traits
Variations
Gene
Have greater genetic variation
Sexual
Asexual
Higher survival rates
Sexual
Asexual
Organisms need to find a mate
Sexual
Asexual
Does not need a mate
Sexual
Asexual
Produce offspring quickly
Sexual
Asexual
Have the exact same genetic makeup
Sexual
Asexual
Problematic with environmental change
Sexual
Asexual
If one organism cannot tolerate change then the rest of the offspring cannot handle it either
Sexual
Asexual
What are some advantages of wild dogs reproducing sexually?
No genetic variation leading to a decrease in their chance of survival in a changing environment.
Greater genetic variation may increase their chance of survival in a changing environment.
The process by which an offspring receives genes from parents is known as _______________
