Genetics 3333 Exam 3 (practice Questions and Answers) Verified In a Chi-square analysis, what general condition causes one to reject the null hypothesis? Always assume alpha is 0.05 unless otherwise stated. usually when the probability value is less than 0.05 when observed >> expected when observed = expected usually when the probability value is less than 0.5 usually when the probability value is less than 0.005 - CORRECT ANSWER-Usually when the probability valu...

1) Which of the following statements is correct in describing the terms monohybrid cross and dihybrid cross? - ANSWER B) A dihybrid cross involves organisms that are heterozygous for two characters that are being studied, and a monohybrid cross involves organisms that are heterozygous for only one character being studied. 2) What was the most significant conclusion that Gregor Mendel drew from his experiments with pea plants? - ANSWER B) Traits are inherited in discrete units and are not...

BIO 182 Exam 2 Questions & Answers 2023 In a simple Mendelian monohybrid cross, true-breeding tall plants are crossed with short plants, and the F1 plants, which are all tall, are allowed to self-pollinate. What fraction of the F2 generation are both tall and heterozygous? a. 1⁄8 b. 1⁄4 c. 1⁄3 d. 2⁄3 e. 1⁄2 e. 1⁄2 The phenotype of an individual a. depends at least in part on the genotype. b. is either homozygous or heterozygous. c. determines the genotype. d. is the ge...

Cell Theory - ANSWER-Discovered in the 17th century 1. All living things are composed of cells 2. The cell is the basic unit of life 3. The chemical reactions of life take place inside the cell 4. Cells arise from only preexisting cells 5. Cells carry genetic information in the form of DNA. This genetic material is passed from parent cell to daughter cell 6 Kingdoms - ANSWER-Bacteria, Archaea, Protista, Fungi, Plantae, and Animalia Prokaryotic - ANSWER-"before nucleus", lacks a memb...

This assignment and unit are overall awarded a distinction. This is Assignment C of Unit 11 and will talk about human inheritance and predicting genetic traits. In this assignment I have given examples of Mendles pea plants, explained F1 and F2 generation, and carried out and investigate Dihybrid and monohybrid inheritance in mazes have concluded my findings using chi-squared and conclusions. I have used drosophila flies, cystic fibrosis, hemophilia, blood group in this assignment as examples.

An allele masked or hidden by the presence of another is referred to as: - ANSWER recessive When two individuals who are heterozygous for a trait mate, what is the probability that their offspring will exhibit the dominant trait? - ANSWER 75% For the results of Mendel's dihybrid cross to be a 9:3:3:1 ratio of traits, what must the relationship of each gene pair be? - ANSWER The genes must be on separate chromosomes

Allele - Gene for particular trait (T) (t) artificial selection - selective breeding of plants and animals to promote the occurrence of desirable traits in offspring Base pairing in DNA - Adenine, Thymine, Guanine, Cytosine Base pairing in RNA - Adenine, Uracil, Guanine, Cytosine Basic monomers and polymers of nucleic acids - bottleneck effect - A change in allele frequency following a dramatic reduction in the size of a population Central Dogma - DNA-transcription-RNA-translation-protei...
