Sexual Reproduction A type of reproduction in which the genetic materials from two different cells combine, producing an offspring The cells that combine are called sex cells Female – egg Male – sperm Fertilization: an egg cell and a sperm cell join together A new cell is formed and is called a zygote

Advantages: Sexual Reproduction Diverse offspring: genetic variation among offspring Half of the DNA comes from mom Half of the DNA comes from dad Due to genetic variation, individuals within a population have slight differences Plants – resist diseases Traits can develop to resist harsh environments that allows an organism survive

Disadvantages: Sexual Reproduction Time and Energy Organisms have to grow and develop until they are old enough to produce sex cells Search and find a mate Searching can expose individuals to predators, diseases, or harsh environmental conditions Fertilization cannot take place during pregnancy, which can last as long as 2 years for some mammals.

Examples: Sexual Reproduction

Asexual Reproduction One parent: organism produces offspring without fertilization Uniform offspring: Because offspring inherit all of their DNA from one parent, they are genetically identical to each other and to their parent

Fission: Asexual Reproduction Fission: Cell division in prokaryotes that forms two genetically identical cells DNA is copied The cell begins to grow longer, pulling the two copies apart The cell membrane pinches inward in the middle of the cell Cell splits to form two new uniform, identical offspring Examples: bacteria, Ecoli, pond critters

Budding: Asexual Reproduction Budding: a new organism grows by mitosis and cell division on the body of its parent The bud, or offspring is identical to the parent The bud, when large enough, can break off of the parent and live on its own Offspring may remain attached and form a colony Examples: Yeast, Hydra, cactus

Regeneration: Asexual Reproduction Regeneration: occurs when an offspring grows from a piece of its parent. Producing new organisms: Sea Stars Sea urchins, sea cucumber, sponges, and planarians Producing new body parts: Gecko Newts, tadpoles, crabs, hydra, and zebra fish

Vegetative Propagation: Asexual Vegetative Propagation: uniform offspring grow from a part of a parent plant Parent plants sends out runners Where the runner touches the ground, roots can grow A new plant is produced even if the runner is broken apart Each new plant is uniform and identical to the parent. Examples: strawberries, potatoes, ivy, crabgrass

Advantages: Asexual Reproduction Enables organisms to reproduce without a mate No wasted time and energy Enables some organisms to rapidly reproduce a large number of uniform offspring

Disadvantages: Asexual Reproduction Because their offspring are identical, there is no genetic variation that can give an organism a better chance for survival Example: If a weed killer can kill the parent, it will also kill the offspring A whole species can be wiped out from a disease Dangerous mutations in DNA – if the parent has the mutation in their DNA, the offspring will have it too.

agenda 1. Come in quietly. 2. You will need your workbook and pick up a Genetics Review from the table. (Review due Thursday) 3. Make sure you have completed the following pages: 1, 2, 14, 15, 16, 17, 18, 19, 21, 23, 34, 35, 36, 37, 38, 39, 40. (Pg. 20 is extra credit) (All pages are due by 12/14…DCA is 12/14 too) 4. Begin Review. 5. If you finish early then you may read pgs. 528-570 in the textbook.
