What is the difference between a recessive and dominant allele? a dominant allele is expressed whenever it is present. a recessive allele is only expressed when an individual has two copied of that allele. 2. What is the difference between heterozygous and homozygous? heterozygous is with two different alleles. for example itwould be Ll. a homozygous is with two identical alleles. for example it would be LL or ll. 3. Using the class data, assume that 1/3 of the cats with short hair were heterozygous. What is the allele frequency of the L allele? (Show your work) (2x1489)+744=3722 2270x2=4540 allele frequency: 3722/4540 = 0.82 also 82% 4. If all the white cats (all white) counted by the class were heterozygous, what is the frequency of the w (not all white) allele? (show your work) 98+4788 = 4886 total: 2492x2=4984 4886/4984=0.98 also 98% 5. What was the allele frequency for the piebald traits: S and s S= 0.482 s=0.518 Fill in the genotype for each of the cats pictured: Write the coat length and color genotype Llww Llww llww llWw llww Exercise : What are the Odds 1. After rolling the dice in the virtual exercise 100 times: what was the probability of rolling the following results Both Dice added up to: 2 15/100 = 0.15 (15%) 7 18/100 = 0.18 (18%) 9 11/100 = 0.11 11 6/10 = 0.06(6%) Attach a screenshot of your results from rolling the dice 100 times on the virtual exercise: (Take a screenshot and attach to the lab report or paste into it). 2. Using the same Virtual tool, what were the probabilities of the same combinations? Both Dice added up to: 2 1/36 = 2.78% 7 6/36 = 16.67% 9 4/36 = 11.11% 11 2/36 = 5.56% Attach a screenshot of the results Did the probabilities change drastically? No Was the change in probability the same for each combination? Select Answer a Why or Why not? random chances cause small differnces between experimental and theoretical probailities. How is the probability of rolling a 6 on a single die calculated differently than rolling a six as a combination between two die? a single die has a 1/6 change of rolling a 6. two dices had 36 possible combinations and only 5 combinations add to 6, so the probability is 5/36 When flipping a coin, what is the probability you will get heads if the coin is flipped once? once: 1/2 (50%) a When the coin is flipped 10 times? 50% about 5 heads expected When the coin is flipped 25 times? 50% about 12-13 heads expected Why is the probability of flipping a coin twice different than flipping two coin at the same time? a a e each flip is independent. flipping a coin twice and flipping two coins at the same time both make four equally ikely outsomes, but one happens after the other while the other happens simultaneously.
