Description

WHAT ARE THE ADVANTAGES AND DISADVANTAGES OF SEXUAL AND ASEXUAL REPRODUCTION? Is one “better” than the other? To answer this question, you will compare 5 aspects of organisms that reproduce sexually with organisms that reproduce asexually. You will begin your study by looking at two different organisms. Once your comparisons have been made, you will share your information with two other students in class to draw general conclusions about each method of reproduction. 1. Choose one sexual reproducer and one asexual reproducer (or one from the “both” category) from the list below. Read about your two species in the attached PDF entitled “Reproductive Strategies…” Sexual

Asexual

Both Sexual and Asexual

Blue-headed wrasse

Amoeba

Brittle star

Duck leech

Salmonella

Meadow garlic

Grizzly bear

Whiptail lizard

Spiny water fleas

Leafy sea dragon Red kangaroo Sand scorpion 2. Read about your two species in the attached PDF entitled “Reproductive Strategies…” 3. Copy/paste the table below into a new Google Doc and fill it out for the two organisms you pick. All info regarding these strategies can be found in the PDF reading. Sexual Relative complexity! of organism (including size): Number of parents who contribute genetic information to the offspring: Reproductive mechanism:

Asexual / Both

Relative amount of parental care: Genetic variation in offspring: 4. when you complete the table for your two organisms, convene with two other students (preferably students that researched difference organisms) in class and compare/contrast the organisms and strategies you researched. 5. Based on your research today, answer the following independently: a) Differentiate between sexual and asexual reproduction and compare the evolutionary advantages and disadvantages of each. (Hint: refer back to Unit 1 & sexual selection) b) Explain why heritable variation is crucial to Darwin’s theory of evolution by natural selection. c) Differentiate between somatic cells and gametes, and how the function of mitosis differs from meiosis. (you may need to look this one up separately online.)...
