1 Today is Wednesday, December 11 th, 2013 Pre-Class: Using a Punnett Square, cross the following two genotypes: Aa x AA. Now answer these questions: -How many different genotypes did you get? -How many different phenotypes did you get? NOTE: Our quiz has been moved to tomorrow, but the review sheet is still due. Please turn that in. In This Lesson: Monohybrid Cross Review (Lesson 3 of 6)

2 Second Pre-Class Pre-Class: Let P be the dominant allele for purple flowers and p be the recessive allele for white flowers. –Pp x Pp What would be the probability of the third offspring of this cross having purple flowers? [Your answer should be in percent form]

3 Today’s Agenda Review monohybrid crosses. Go deeper into genetics (dihybrid crosses) (maybe). By the end of today you (all students) should be able to complete and analyze a monohybrid Punnett Square with ease.

4 Sequence of Review Step 1: –Lab Group: Complete Quia quiz: Genetics Practice Problems. Step 2: –Individual: Complete Pages of your Genetics Worksheets. Step 3: –Partners: Class review game for genetics.

5 Review Question 1 In humans, brown eyes are dominant to blue eyes. Two parents with brown eyes have a daughter with blue eyes. What is/are the possible phenotype(s) of the parents? –Brown eyes.

6 Review Question 2 In humans, brown eyes are dominant to blue eyes. Two parents with brown eyes have a daughter with blue eyes. What is/are the possible genotype(s) of the parents? [be sure to select the correct allele letter] –Bb.

7 Review Question 3 In humans, brown eyes are dominant to blue eyes. Two parents with brown eyes have a daughter with blue eyes. What is/are the possible genotype(s) of the daughter? [be sure to select the correct allele letter] –bb.

8 Review Question 4 In mice, brown fur color is dominant to gray fur color. A homozygous dominant male mouse is crossed with a heterozygous female mouse. What is the phenotype of the female mouse? –Brown.

9 Review Question 5 In mice, brown fur color is dominant to gray fur color. A homozygous dominant male mouse is crossed with a heterozygous female mouse. In percentage form, what is the likelihood of the first offspring being brown? –100%

10 Review Question 6 In mice, brown fur color is dominant to gray fur color. A homozygous dominant male mouse is crossed with a heterozygous female mouse. In percentage form, what is the likelihood of the first offspring being heterozygous? –50%

11 Review Question 7 In mice, brown fur color is dominant to gray fur color. A homozygous dominant male mouse is crossed with a heterozygous female mouse. In percentage form, what is the likelihood of the second offspring being heterozygous? –50%

12 Review Question 8 In mice, brown fur color is dominant to gray fur color. A homozygous recessive male mouse is crossed with a heterozygous female mouse. What is the genotype of the male mouse? [be sure to pick the correct allele letter] –bb.

13 Review Question 9 BONUS NON-BIOLOGY QUESTION You may wager any or all of your points. Category: Not Genetics What was the first European country to settle Manhattan? –Holland/The Netherlands

14 Review Question 10 In mice, brown fur color is dominant to gray fur color. A homozygous recessive male mouse is crossed with a heterozygous female mouse. In percentage form, what is the likelihood of the first offspring being homozygous dominant? –0%

15 Review Question 11 In mice, brown fur color is dominant to gray fur color. A homozygous recessive male mouse is crossed with a heterozygous female mouse. In percentage form, what is the likelihood of the first offspring being brown? –50%

16 Review Question 12 In mice, brown fur color is dominant to gray fur color. A homozygous recessive male mouse is crossed with a heterozygous female mouse. In percentage form, what is the likelihood of the first offspring being gray? –50%

17 Closure Any questions? WhipAround for the unit so far!
