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 Reproduction Half of the genes for each trait come from the male parent and half come from the female parent

Sexual reproduction § § Sexual reproduction results in genetic diversity due to the large

Sexual reproduction § § Sexual reproduction results in genetic diversity due to the large number of gene combinations that can occur

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.

Animals produce offspring asexually through: It will drop off and attach near the parent.

Animals produce offspring asexually through: It will drop off and attach near the parent. This is very important in forming coral reefs.

Regeneration (starfish) § Many organisms can regrow some missing parts, but only a few can produce complete new organisms. The starfish is one of these.

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.
