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…

Summary IntroductionTo determine:Whether the given statement “All traits are inherited in a Mendelian pattern.” is true or false.Introduction:Some traits are transferred to the offspring from their parents; this process is called inheritance. Mendel gave some laws to describe how genetic transmission of traits take place, the inheritance pattern that follows the law of Mendel is known as Mendelian inheritance. Mendel gave the law of segregation, the law of dominance, and the law of independent assortment.
Punnet square problems A=Codominant; B=Codominant; O=Recessive Mary is homozygous for type A blood. Steve is homozygous for type O blood. If they have children, what are the possible phenotypes and genotypes of their children, and what is the probability of each? Mary and Steve have a son, Brad. Brad’s wife, Samantha is heterozygous for type B blood. If they have children, what are the possible phenotypes and genotypes of their children, and what is the probability of each? Stella loves roses and decides to cross her red rose with her white rose. All of the resulting offspring of this cross are pink roses. What can you say about the red and white alleles as a result of this cross? Stella decides to cross two of the pink roses. What are the possible genotypes and phenotypes of the offspring and the probabilities of each? DNA replication, Transcription and Translation problems It is S phase of the cell cycle, and time to replicate the cell’s DNA. Using the following strand of DNA…

Give the sex of the individual. ______________c. Based from the karyotype, identify the name of the genetic condition of the individual. Listdown two (2) distinctive characteristics of the affected individual.
Single gene Mendelian inheritance patterns: if you are told the phenotype of the parents and whether the trait is dominant or recessive etc, be able to predict the genotype of the children. If you are told the phenotype of the parent as well as the inheritance pattern, be able to predict the parent’s genotype. Be able to set up and use a Punnett square to solve problems and make predictions. Be able to explain the major steps in how information from our genes is used to make proteins. Or to show it in a labeled diagram. Be able to explain whatis transcription, translation. Where in the cell do these processes occur? In what order? What type of molecules are being made [DNA, RNA, protein]? What are their building blocks? What is a mutation? How can a mutation in DNA cause a change in a protein? (use the following terms to answer: codon, transcription, translation, mRNA). What is gene expression? Why is regulation of gene expression important for normal…
2. Uniparental disomy is a rare phenomenon in whichonly one of the parents of a child with a recessivedisorder is a carrier for that trait; the other parent ishomozygous normal. By analyzing DNA polymorphisms, it is clear that the child received both mutantalleles from the carrier parent but did not receive anycopy of the gene from the other parent.a. Diagram at least two ways in which uniparentaldisomy could arise. (Hint: These mechanismsall require more than one error in cell division,explaining why uniparental disomy is so rare.)Is there any way to distinguish between thesemechanisms to explain any particular case ofuniparental disomy?
