You guys rock! Great effort on our Kahoot!
Tonight: Take a few minutes to read through your study guide to lock down your background knowledge of genetics. Test is tomorrow, Thursday, March 12.
EXTRA CREDIT AVAILABLE: As stated on Remind service, you can get 10 POINTS EC on your test if you study 30 minutes or more for your genetics test, as stated in a note signed by a parent or guardian that you bring me tomorrow.
Selected answers from Study Guide are below. If you need one that isn't shown here, ask me by email this afternoon ( mgoldsmith@ci.stamford.ct.us or MGoldsmith@StamfordCT.gov), or before the test tomorrow!
2. What are some differences between Sexual reproduction and Asexual reproduction?
a.
Number
of parents _____2_____ _____1___
b.
Compare
parents to offspring each contribs1/2 of genes __identical_______
c.
Cell
types taking part _sex cells_ body (somatic)
d. Number of steps does not apply--error
e. (blank) does not apply--error
f. Which
organisms reproduce in each way (answer next parts with yes or no)
g.
Can
humans? __yes__________ _no______
h.
Can
plants? __yes__________ __yes__________
i.
Can
bacteria? ____no__________ __yes____________ 17. How would you symbolize the dominant gene for yellow peas seeds? Y
21. Genetic shorthand: If round shell shape is dominant and shown by R, then how would you write the symbol for the wrinkled recessive gene? __ r
24. What is probability?
The likelihood
of each possible outcome. Ex: Mendel found that the probability of a seed being
green was about 1 out of 4 in every third generation of pea plants. Also, a
branch of mathematics studying the type and number of results to expect in a
given number of trials or chances.
25. What does it mean to say that
something is “random”?
unpredictable,
without reason or pattern
26. Contrast Marfan's syndrome (discussed in class) with AIDS/HIV or Ebola or Influenza or Tuberculosis or Hepatitis C (studied in our Cell Biology unit). How are they caused?
Marfan's Syndrome is a genetic disease, caused when a person inherits the genes that, when expressed, cause the symptoms (heart trouble, elongated features, loose joints, unusual height). AIDS/HIV, Ebola, Influenza, Tuberculosis or Hepatitis C are caused by a virus (except that Tuberculosis is caused by bacteria).
29 . How are meanings of the terms similar and/or different?
32. What is Diversity? In the context of Genetics, "Diversity" refers to a
variety of traits that can be found in
different offspring from two parents. As we examine more traits, we find even
greater diversity. Diversity is beneficial because when members of species have different advantages, abilities and strengths, some of them are more likely to survive no matter what challenges they face. In other words, diversity makes it more likely that the species will survive. ..
1. 36. Nature
vs. nurture -
Scientists often argued about whether an organism’s traits are caused by the
world around them (ex: strong from lots of exercise) or because of the genes
they inherited from their parents (ex: lizard’s green skin, dog’s blue
eyes). Answer (1-5 sentences each) these
questions on a piece of paper that you attach to this guide:
a.
Is
a person’s body height caused by genes or environment? For example, are 2 adults who never grow
taller than 5 feet likely to have a child over 7 feet tall?
Can their child grow taller, however,
because the child got better nutrition than the parents, or because the parents
were exposed to disease or toxins that the child avoided?
For example, height
is affected both by genetic inheritance, and by environmental exposures to
toxins, infectious diseases, and by good nutrition (or the lack of it), etc. 37. Do you agree with this statement or not: “…effective effort drives development. In other words: people get smart by working hard”. From The Efficacy Approach, http://efficacy.org/Strategy/tabid/246/default.aspx#/?CSSTabID=1, The Efficacy Institute, 2012.
Yes
- I’ve seen students and others working
harder and quickly showing objective improvements in test scores and other indicators of mental function. There is plenty of scientific evidence to
back up the idea that people can improve their intellectual function by their
effort.
