Directions: Use the Reproduction Table Reading from my website. The link is titled 6.2
Reproduction Table Reading. The reading gives you information about each of the 6 organisms.
You can access the reading using your iPad or laptop. You need to read each organism and put
an x in the box with the trait that organism has.

Answer:
•
Reproduction we have talked most about this year
•
Genetic information (the DNA) comes from 2 parents
•
Offspring gets genetic information from 2 gametes
mother’s egg and father’s sperm
•
Offspring gets 50% of the DNA from the mother and 50% of the DNA from the fater
Sperm have 50% of the DNA and Eggs have 50% of the DNA
•
Egg from the mother Sperm from the father.
•
The offspring vary: No 2 offspring are the same
Siblings have the same parents but get a different set of each chromosome
The 23 chromosomes in one sperm are not the same as the 23 chromosomes in the second sperm

Direct Instruction: 6.2 Reproduction
Period:
•
New concept: Only seen in some plants, very small eukaryotes, and prokaryotes like bacteria
•
Genetic information (the DNA) comes from 1 parent
•
Offspring gets all its DNA from one parent
No sperm or egg: Just new offspring
•
2 main methods: Binary Fission and Budding
•
Binary Fission: A single celled organism duplicates its DNA (makes a copy of its DNA) and then divides into 2
identical copies of itself.
A cell splits into two identical CLONES of itself
•
Budding: A bud (part) of the parent organism is removed. The bud grows into a brand new identical organism.
The offspring is identical: The two product cells are the exact same
