Concept explainers
When working out genetics problems in this and succeeding chapters, alwaysassumethatmembersof the P1 generation are homozygous, unless the information or data you are given require you to do otherwise.
To assess Mendel's law of segregation using tomatoes, a true-breeding tall variety (SS) is crossed with a true-breeding short variety (ss). The heterozygous tall plants (Ss) were crossed to produce the two sets of F2 data as follows:
Set 1 | Set II |
30 tall | 300 tall |
5 short | 50 short |
(a) Using chi-square analysis, analyze the results for both datasets. Calculate x2 values, and estimate the p values in both cases.
(b) From the analysis in part (a), what can you conclude about the importance of generating large datasets in experimental settings?

- MODIFIED TRUE OR FALSE. In the following items, read each statement carefully. I. The Mendelian pattern of inheritance is a general term that refers to any pattern of inheritance in which traits do not segregate in accordance with Mendel’s lawsII. As an example, a characteristic may be controlled by one gene with two alleles, but the two alleles have a same relationship like the simple dominant-recessive relationship a. The first statement (I) is correct and the second statement (II) is wrong b. The first statement (I) is wrong and the second statement (II) is correct c. Both statements are correct d. Both statements are wrong MODIFIED TRUE OR FALSE. In the following items, read each statement carefully. I. The continuity of life from one cell to another has its foundation in the reproduction of cells by way of the cell cycle.II. The cell cycle is an orderly sequence of events in the life of a cell from the division of a single parent cell to produce…arrow_forwardpls dont copy existing answers or i will dislike your answer thanks Phenylketonuria (PKU) is a disorder caused by a recessive allele. Two carrier individuals have progeny. Answer the following questions in order and show solutions whenever relevant. 1. If they have a normal child, what is the probability that he or she will be heterozygous? 2. If they have three children, what is the probability of having 2 affected children and one normal child?arrow_forwardKeeping it in the family!”- How do you think consanguinity is increasing the risk factors of genetic disorders? Explain with examples (at least two). It won’t be possible to change the tradition all of a sudden. If you are a clinical geneticist, how you will be managing this type of community?arrow_forward
- Question: Red color (R) allele is dominant over blue color (r) for carnations (a type of flower). You will cross a heterozygous red carnation with a blue carnation. Show all your work filling out the required parts of the diagram. Then, select the correct statement below. (Picture below) 1. 75% red - 25% blue 75% heterozygous - 25% homozygous 2. 75% red - 25% blue 75% heterozygous - 25% homozygous 3. 50% red - 50% blue 50% heterozygous - 50% homozygous 4. 25% red - 75% blue 25% heterozygous - 75% homozygousarrow_forwardInstruction - Please answer them correctly - Please answer all of them, they are connected. PEDIGREE ANALYSIS and SYMBOLOGY Examine the pedigree which has X linked Dominant inheritance of disorder. Use letter X* (asterisk denotes disorder) as genotype of the individuals which can be XX, XY, X*X*, X*X and X*Y. a. What is the genotype of IV-6? b. What is the genotype of III-6? c. What is the genotype of II-3? d. What is the genotype of III-8? e. If couple I-1 and I-2 will have a son, what is the probability of having the disorder? f. If couple III-8 and III-9 will have another child, what is the probability of having the disorder? g. Theoretically, if individual IV-3 and individual IV-5 will marry and will have a child, what is the probability of having a child without the X-linked disorder?arrow_forwardPEDIGREE ANALYSIS — please answer all of them, they are all connectedarrow_forward
- True or false? All traits are inherited in a Mendelianpattern.arrow_forwardQuestion:- Why did Mendel observe the principle of uniformity? Because all traits in peas are fully controlled by genotype Because Mendel only worked with discontinuous traits, which give only two classes of phenotypes Because Mendel worked with very large number of progeny All of the abovearrow_forwardHeredity Unit Test 4 of 134 of 13 Items Item 4 Mendel crossed a purebred tall pea plant with a purebred short pea plant and all of the offspring came out tall.

- Autosomal Recessive Problem: What is probability of individual 2 III in pedigree 1 and individual 1 III in pedigree 2 to have an affect child?arrow_forwardHi, I'm having trouble with my study guide for my upcoming genetics exam. If someone could please help with work shown and an explanation it would help so much! Thank you!! 2a. The pedigree below represents inheritance of rare condition. What pattern of inheritance is most consistent with the data? Assign alleles to all individuals to support your answer. If an allele is unknown, assign it a ? symbol. NOTE: Individuals whose phenotype or genotype cannot be determined are assumed to be unaffected and homozygous, unless otherwise indicated. 2b. In addition to the alleles you’ve indicated, describe 2 overall features of the pedigree that make it consistent with your chosen form of inheritance. 2c. Based on your mode of inheritance, what is the probability that the child of couple IV-4 x IV-5 will be affected? Show your work. attached is the pedigreearrow_forwardSolving complex genetic problems with the rules of probability (3 traits) 1.
