Correct! Guanine Question 6 0 / 1 pts Chromosomes are made of chromatin, which of the following is a component of chromatin? You Answered Correct Answer RNA Nucleosomes Question 7 1 / 1 pts In the process of transcription 3 of 7 4/20/17 1:56 PM Module 1 Worksheet: MCELLBIX143-037 Genetics Correct! https://onlinelearning.berkeley.edu/courses/660798/quizzes/1071396 DNA is copied to make another linear molecule called ribonucleic acid Question 8 0 / 1 pts Mendel’s law of equal segregation states that: You Answered Correct Answer A hereditary factor, or gene, is necessary for producing a phenotype. In meiosis, the members of a gene pair separate equally into the eggs and sperm. Question 9 4 of 7 0 / 1 pts 4/20/17 1:56 PM Module 1 Worksheet: MCELLBIX143-037 Genetics https://onlinelearning.berkeley.edu/courses/660798/quizzes/1071396 You just brought a pet hamster home from the pet store. You name the hamster Chocolate because she has brown fur. After a few weeks at home you are surprised when Chocolate has babies. Interestingly, all 12 of her pups have white fur. You do some research and find out that brown fur color is recessive and white fur color is dominant in hamsters. Based on this information, the unknown father of the pups is mostly likely what genotype and phenotype with respect to fur color? You Answered The father is heterozygous and has white fur Correct Answer The father is homozygous dominant and has white fur Question 10 0 / 1 pts In daisies, flower color is controlled by a single gene where purple flower color is dominant and red flower color is recessive. You cross a purple-flower daisy plant to a red-flower daisy plant. In the F1 you observe a 1:1 phenotype ratio of purple-to-red flowered progeny. What are the most likely genotypes of the parents? Correct Answer The purple parent is heterozygous and the red parent is homozygous You Answered Impossible to tell. You would need to self the F1 progeny and observe the F2 progeny ratios to be able to determine the parental genotypes Quiz Score: 6 out of 10 5 of 7 4/20/17 1:56 PM Module 1 Worksheet: MCELLBIX143-037 Genetics 6 of 7 https://onlinelearning.berkeley.edu/courses/660798/quizzes/1071396 4/20/17 1:56 PM Module 1 Worksheet: MCELLBIX143-037 Genetics 7 of 7 https://onlinelearning.berkeley.edu/courses/660798/quizzes/1071396 4/20/17 1:56 PM
