Meiosis / Genetics Standards
Meiosis Standards for End of Course Exam (Answer 4/23)
+ √ _
I can describe the process of meiosis (e.g., each egg or sperm cell receives only one representative
chromosome from each pair of chromosomes found in the original cell) and/or product of meiosis
(e.g., egg and sperm cells with only one set of chromosomes).
I can describe that the processes of recombination during meiosis (e.g., segregation, independent
assortment) result in a unique combination of genetic information in the egg or sperm cell.
I can describe the relationship between the unique combination of genetic information in an egg or
sperm cell and the differing characteristics in offspring from a single set of parents.
I can describe the process of fertilization as restoring the original chromosome number (e.g., an egg
and sperm, each with half the number of chromosomes of the original cell, combine to restore the
number of chromosomes from the original cell).
I can describe that the process of fertilization allows for variation among offspring from a single set of
parents.
