●● Now imagine that the same two lizards were sitting on a dune of
white sand. Which lizard do you think the hawk would then most likely
try to catch? Why?
Answer: The hawk would then be most likely try to catch the brown
lizard because of how the color stands out more, in contrast to the white
lizard sitting a dune of white stand.
●● The change in the circled offspring's genotype was caused by a
mutation. A mutation is a change in a gene. Mutations happen when a
mistake is made when a cell's
chromosomes are copied. How might mutations introduce variation into
a population?
Answer: Mutations might introduce variation into a population because
there are new alleles on the genes, which means different characteristics
will be produced within the organism. This affects the population's
genetic variation and it can be passed down on to the next generation.
●● Can a single offspring inherit both chromosomes from one parent?
Answer: No, they are unable to inherit both chromosomes from one
parent because the chromosomes are randomly distributed (aka
independent assortment of chromosomes)
