Learning Target: 1. Continue mastering Punnett Squares 2. How do the offspring of asexual and sexual reproduction compare ***Create a face due today*** Science Starter: Patrick recently married Patti. He is considered a purebred for tall head shape (T), which is dominant over a short head (t). If Patti is a short headed woman, what type of heads would their children have? Create Punnett Square to show the possible genotypes and phenotypes. (This is Question #5 on Bikini Bottom Genetics Quiz!)

Sexual/Asexual Reproduction
7.14B Compare the results of uniform or diverse number of offspring from sexual repro- duction or asexual reproduction
3
Reproduction Sexual –diverse offspring – combo from two parents
4
Sexual Reproduction Genetic material is donated from two parents via the sperm and egg
5
Sexual Reproduction Half of the genes for each trait come from the male parent and half come from the female parent
6
Sexual reproduction Sexual reproduction results in genetic diversity due to the large number of gene combinations that can occur
7
Offspring differ from each parent and from each other
Sexual Reproduction Offspring differ from each parent and from each other
8
Asexual – uniform offspring – copy
Genetic material is donated from only one parent Offspring are identical to the parent and to each other
9
Animals produce offspring asexually through:
Binary fission happens when bacteria divide
10
Animals produce offspring asexually through:
Budding (hydra) - Some organisms like sponges, hydra, and coral can form a mass of cells called a "bud" that specialize to form a new organism on the side of the parent.
11
Animals produce offspring asexually through:
It will drop off and attach near the parent. This is very important in forming coral reefs.
12
Regeneration (starfish)
Many organisms can re-grow some missing parts, but only a few can produce complete new organisms. The starfish is one of these.
13
Regeneration (starfish)
As long as any ray of the starfish is connected to the nerve ring, it can form an entirely new starfish. Another example is the flatworm called planaria.
