Practice Quiz - Punnett Square, Variation, and MutationsVersion en ligne Practice Quiz - Punnett Square, Variation, and Mutations par Benjamin D Morgan 1 How many boxes would say BB? a 1 b 2 c 4 d 0 2 Brown is dominant to green. What is the probability of these parents having green offspring? a 1/4 b 2/4 c 3/4 d 4/4 3 The dominant trait is a yellow pea seeds b green pea seeds c there is no dominant seed d Jolly green giant 4 To be a yellow seed genotype must be a aa b Aa c AA d AA or Aa 5 A Punnet Square will a tell you exactly what your offspring will look like b increase the chance you pass on recessive traits c predict genotypes and phenotypes in offspring d have no purpose but for Taylor to give us extra assignments 6 How do two purple flowers produce white flower offspring? a They cant have white flowered offspring b Both flowers are heterozygous and can pass on the white allele c They are both homozygous Dominant d They do not have the recessive allele in their genotype 7 Both parents in this Punnet square a are homozygous dominant b are homozygous recessive c are heterozygous d have blue eyes 8 What allele combination should go in the missing box? a AA b Aa c aa d none of these 9 If B = brown hair and b = blonde hair, what is the probability of brown hair? a 25% b 50% c 0% d 75% 10 T - tall and t = short In the punnett square below, what belongs in the missing square a tt b Tt c Bb d TT 11 Dominant alleles are represented by a: a male gene b lowercase letter c recessive trait d capital letter 12 BB, Bb, and bb are examples of _________________ a Dominant b Homozygous c Genotype d Phenotype 13 This is the expression of alleles. It is the observable trait we can see _________________ a Dominant b Homozygous c Genotype d Phenotype 14 In some animals, brown eyes (B) are dominant over blue eyes (b). Which of these genotypes will complete the Punnett Square to the right? a B b bb c Bb d BB 15 What would go into punnet square 1 a Bb b BB c bb d all choices 16 What would go into punnet square 2 a BB b Bb c bb d all choices 17 What would go into punnet square 3 a BB b Bb c bb d all choices 18 What would go into punnet square 4 a BB b Bb c bb d all choices 19 What would go into punnet square 1 a WW b WB c BB 20 What would go into punnet square 3 a WW b WB c BB 21 What would go into punnet square 2 a RR b RG c GG 22 If two organisms reproduce sexually, then their offspring will exhibit a genetic makeup that is - a identical to only one parent b identical to all of its siblings c a unique combination of traits d the recessive traits of each parent 23 How many parents does asexual reproduction involve? a one b two c three d four 24 The offspring from asexually reproduced organisms are? a Different than their parents b Identical to parents c Like a combination from both parents d A different species 25 utations are a source of _______________. a Variation b Disease c Polypeptide 26 Any change in the sequence of DNA is... a Transgenic Shift b Single Genotype c Monohybrid Trait d Mutation 27 Are all mutations bad? a yes b no 28 Mutations: a are permanent changes in the DNA sequence or structure b produce allelic variation c are more likely to neither harm or help the organism d all of the above 29 Which of the following is heterozygous? a FF b tt c Gg d RR 30 Which of the following is homozygous recessive? a rr b AA c TT d Ff 31 Which of the following is homozygous dominant? a Jj b Rr c MM d ee 32 Mark is heterozygous. If B is for brown hair, and b is for blonde hair, what is Mark's phenotype? a Brown Hair b Blonde Hair c Brown and Blonde Hair d Black Hair 33 Mark is heterozygous. If B is for brown hair, and b is for blonde hair, what is Mark's genotype? a BB b bb c Bb d bB 34 Genetic variation describes offspring that have different traits, such as Paulie and Nicole. Offspring with different traits must be a result of a asexual reproduction b sexual reproduction 35 Why do Paulie and Nicole have so many different traits? a Paulie got more DNA from their mom, while Nicole got more DNA from their dad b Paulie and Nicole both got half their DNA from mom and half from dad, but they get different genetic combinations c Paulie and Nicole are not actually related d Paulie's DNA has a lot of mutations, which are very common 36 What is another reason for genetic variation besides sexual reproduction? a Partial mating b Asexual reproduction c Unequal chromosome distribution d Mutation 37 Sara has red hair. No one else in her family has red hair except her grandmother. How is this possible? a Red hair is random and cont connected to past generations b The genetic information for red hair was destroyed in the rest of Sara's family c Sara shares DNA with Grandma, but not her own parents d Grandma passed down some genetic information from her DNA to Sara 38 A pure plant that has a genotype of GG is crossed with a pure plant that has the genotype gg. What are all the possible genotypes of the offspring? a GG, gg, and Gg b only Gg c only GG d GG and gg 39 The differences in the sets of alleles between individuals in a population a genetic variation b gene c allele d none of the above 40 An organism's appearance or other detectable characteristic a genotype b phenotype c allele d genetic variation 41 Genetic variation allows for... a Species to change over time b Populations to survive c Differences in a population d All choices 42 What causes genetic variation? (pick all correct choices) Choose one or more answers a Mutations b Sexual Reproduction c Asexual Reproduction d Mitosis e cell division 43 A mutation occurs at the genetic level. What does this cause? a The gene (allele) makes a different protein b The gene (allele) codes for a different trait
