Babies' Traits: Similar to Parents?

Today's lesson focuses on whether babies of living things inherit their parents' traits. Explore trait variations in desert beetles and predict outcomes based on parents' traits. Engage in discussions about mouse parentage based on shared traits. Consider similarities and differences in baby animals and plants resembling their parents.

1. VARIATION IN TRAITS LESSON 6A Do Babies of Living Things Have the Same Traits as Their Parents? How Do You Know?

2. Review: Trait Variations in Desert Beetles How did variations in the color trait affect which beetles survived in our simulations? Scarab beetles RES.C2.VIT.L3HO.003 Photo courtesy of Pixabay.com Photo courtesy of Wikimedia.com Photo used with permission from BSCS

3. Review: A New Science Idea If living things survive long enough, they can produce young (babies). Today, we ll explore what happens when living things have babies.

4. Todays Focus Questions Do babies of living things have the same traits as their parents? How do you know?

5. What Do You Predict? A green mother beetle and a green father beetle have a baby beetle. What color do you think the baby beetle will be? Mother Father Photograph by Dean Johnson Photo used with permission from BSCS

6. Are You My Parents? Which pair of adult mice do you think might be the baby mouse s parents? Why do you think so? Baby Mouse Possible Parents

7. Data Table of Mouse Traits Adult Mice Number of Legs Number of Ears Fur Color Length of Tail Color of Eyes Color of Nose

8. Which Mice Are the Parents? 1. Share your data in your group and discuss which pair of adult mice might be the baby mouse s parents. 2. Talk about which of the baby mouse s traits are the same as the traits of each pair of adult mice, and which are different. 3. During this discussion, keep our focus questions in mind: Do babies of living things have the same traits as their parents? How do you know? 4. As a group, come up with a sentence that explains which pair of adult mice might be the baby mouse s parents and why you think so.

9. Todays Focus Questions Do babies of living things have the same traits as their parents? How do you know? Baby animals, like the baby mouse, have traits that make them look like their parents, but what about baby plants? Do you think they have the same traits as their parents?

10. What about Baby Plants? If two adult cacti have a baby, what traits do you think the baby cactus might have? Draw a picture of the baby cactus and label the traits you think are the same as the parents traits. Picture of two cacti RES.C2.VIT.L6HO.007 Photo courtesy of Pixabay.com

11. Next Time Today, we investigated whether babies of living things have the same traits as their parents. The data we collected showed that the baby mouse shared most of its traits with the pair of brown mice we think are its parents. Next time, we ll think about why babies of living things have traits that are similar to, but not exactly like, their parents traits.
