1. a population of birds suddenly decrease their frequency of sexual reproduction
2. meiosis
3. does not impact evolution
4. penguins reproduce sexually, producing offspring that look different from one another
5. an old growth forest with trees that are over 1,500 years old

lol is 100% correct for the genetic variation and evolution quick check in biology
lol is 100% correct!
100%, Thanks to lol.
LOL IS RIGHT<3
lol is still correct :D <3

LESSON 2 Genetic Variation and Evolution
1. a population of birds suddenly decreases their frequency of sexual reproduction
2. meiosis
3. does not impact the evolution
4. penguins reproduce sexually, producing offspring that look different from one another
5. an old-growth forest with trees that are over 1,500 years old
100% correct I promise

L3 genetic variation and evolution
Which of the following scenarios will decrease the genetic variation of a population?
> a population of birds suddenly decrease their frequency of sexual reproduction
Two of the main drivers of genetic variation are mutations and genetic recombination. During which process can these two events occur?(1 point)
> meiosis
If a fish is able to breathe outside of water but does not reproduce, that trait (1 point)
> does not impact evolution
In which of the following scenarios would evolution by natural selection take place? (1 point)
> Penguins reproduce sexually, producing offspring that look different from one another
Which type of environment would tend to reduce genetic variation in a population because of evolution by natural selection? (1 point)
> an old growth forest with trees that are over 1,500 years old
100% :)
