Biology 101 Bio Beyond Lesson 3 Questions and Answers 100% Solved Select the traits that best describe Priya No Dimples No Widows Peak No Cleft Chin Detached Earlobe Select the traits that best describe Blake Dimples A Widow's Peak Cleft Chin Attached Earlobe Make a prediction describing what you believe their children will look like. For each characteristic... Their children will have traits that resemble either their mother's or their father's traits (either two attached earlobes or two detached earlobes) Given the data you collected from the couple's children, which statement best describes the traits in Priya and Blake's children? For each characteristic, their children will have traits that resemble either the mother or the father's traits. Are there any traits that are found in a parent, but seem to "disappear" in all their children? No Widow's Peak Attached Earlobe Gregor Mendel's experiments centered around growing and observing which plant? Pea Plants Why did Mendel choose to grow pea plants for his experiment? Select all that apply They grow and mature quickly. Their traits are easily noticeable. Based on this cross, what color do you predict the offspring will be? All Purple Select two family trees: one that represents purebred white pea plants AND one that represents purebred purple-flowered plants. 2. Pure purple-flowered plant. 4. Pure white-flowered plant. Purple flowers Judging from the results above, what percent of the offspring should have only Purple flowers? 100 White Judging from the results above, what percent of the offspring should have only White flowers? 0 Light-purple (from mixing both white and purple) Judging from the results above, what percent of the offspring should have light-purple flowers? 0 What is the purpose of self-fertilizing one of the offspring of your first cross? To determine if the white-flower trait may be present but "hidden" in the F1 flowers After crossing two flowers from the F1 generation, what do you predict the offspring will look like? Make a hypothesis and rate your confidence below. Some purple and some white flowers Purple flowers Judging from the results above, what percent of the offspring should have only Purple flowers? 75 White Judging from the results above, what percent of the offspring should have only White flowers? 25 Light-purple (from mixing both white and purple) Judging from the results above, what percent of the offspring should have light-purple flowers? 0 Which of the following explanations best explains how a white flower emerged in the F2 generation? The white flower trait was present in the F1 generation's purple flowers but not visible until the F2 generation. What is the recessive trait in this cross? Green Seeds What is the dominant trait in this cross? Yellow seeds Identify the coat color trait for the dog above: Brown Coat Identify the coat color trait for the dog above: Yellow Coat Label the generations in this family 1= P Generation 2= F1 Generation What is the dominant trait in this cross? Brown Coat What is the recessive trait in this cross? Yellow Coat Which of the following is an example of an allele, or a particular version of a characteristic? Select all that apply. Blue Eyes Brown Hair Cleft Chin Attached Earlobe Pink Flower Yellow seed Which allele is the dominant allele in the image above? The red-flower allele because it is represented by uppercase letters Select the genotype for the following purebred parent plants and their offspring: 1= YY 2= yy 3= Yy Homozygous RR rr pp PP TT YY Heterozygous tT Tt Rr rR Yy Select the dominant alleles R Y Select the phenotype of the following genotypes Rr= Round seeds rr= wrinkled seeds YY= yellow pods yy= green pods Using genotypes, we can now explain why our first cross of two pure breeds (white and purple-flowered pea plants) resulted in all purple flowers. Remember, offspring receive one allele from each parent. Use this to answer the questions below. PP/Purple flowers pp/White flowers Pp/Purple flowers Start by arranging the alleles of two F1 plants into the sex cells below. Plant 1: Pp P p Plant 2: Pp P p Cross two plants from the F1 generation. Use their alleles to create all possible combinations for their offspring below. Pp/PP/pP/pp Label the offspring of this cross with their correct phenotype (appearence). Pp= Purple PP= Purple pP= Purple pp= white What will be the genotype of the purebred wrinkled green-seeded pea plant? 1: yyrr What will be the genotype and phenotype of the offspring of these two plants? Genotype: YyRr Phenotype: Yellow and round Make a hypothesis: What will the offspring of two F1 "YyRr" plants will look like? (Select all that apply) Yellow, round seeds Green, wrinkled seeds Based on these results, which statements fit your observations? Select all that apply. The yellow seed trait can pair with a wrinkled seed trait A green seed trait can pair with a round seed trait Which statement best supports this law? Parents with two different traits for two characteristics have an F2 that can have any combination of traits from both grandparents.
