2022 Genetics Final Exam: BIOL 301(BIO 3303) Final Exam Mendel performed many types of crosses, including those in which the same genotypes are crossed but the sexes of the parents are switched. Th... ese are known as What is the process of synthesizing single-stranded RNA from template DNA? What is the process of synthesizing proteins from mRNA sequences In peas, the round allele is dominant over the wrinkled allele. if a plant with round peas is crossed to a plant with wrinkled peas, all of the resulting plants have round peas. What is the genotype of the parents in this cross? In peas, the yellow allele is dominant over the green allele. If a plant with yellow peas is crossed to a plant with green peas, the resulting plants are 50% yellow and 50% green. What is the genotype of the parents in this cross? what genotypic ratio would you expect to see among the progeny of a monohybrid cross A couple has three children. What is the probability that they would have three boys Humans have a gene, "T", that is involved in muscle formation of the tongue. Individuals with the one allele can roll their tongues, while individuals with the other allele cannot. If both parents can roll their tongues, but their child cannot, what can be said about the mode of inheritance? In peas, axial (A) flower position is dominant to terminal (a), tall (L) is dominant to short (l), and yellow (Y) is dominant to green (y). If a plant that is heterozygous for all three traits is allowed to self-fertilize, how many of the offspring would be dominant for all three traits? In peas, axial (A) flower position is dominant to terminal (a) and tall (L) is dominant to short (l). If a plant that is heterozygous for both traits is allowed to self-fertilize, how many of the offspring would also be heterozygous for both traits? The law of independent assortment would predict that the F2 progeny of F1 heterozygous plants will exhibit a: During which stage or phase of the cell cycle does the cell replicate its chromosomes? Certain kinds of cells (e.g., comes cells in the eyes and bones) mature and differentiate into a slate in which they have a specialized function but do not divide or progress through the cell cycle. These cells are "stuck" in which stage? Which organelle migrates during M phase to form the two opposite poles of the dividing cell and acts as the source of the spindle fiber microtubules? Which structure is responsible for chromosome movement during cell division? During meiosis 1, when do homologous chromosome pairing and recombination occur What type of allele is often detected as a distortion? Morgans analysis of white-eyed male Drosophila mutaitons helped exampl Centromeres are In the nucleosome structure What is the cellular function of ribosomes RNA molecules consist of microtubules are chromosomes consist of DNA synthesis occurs chromosomes separate and move to opposite poles of the cell during diploid cells of humans have 46 chromosomes. How many chromosomes would a human cell have after meiosis most people with the dominant mutant polydactyly allele have extra digits, but atleast 25% have a normal number. what is the genetic explanation in a cell, tRNA can be covalently linked to a histone protein is synthesized during in some plants, a heterozygote is pink, intermediate between the 2 homozygotes red and white. the pink A very common type of red-green colorblindness in humans is caused by a mutation in a gene located on the X chromosome. Knowing that the mutant allele is recessive too the wild type, what is the probability that the son of a woman whose father is colorblind is going to also be colorblind? After which stage of the cell cycle does the cell divide the different forms of genes are called pairing of homologous chromosomes connected and exchange piece with one another DNAbackbone,replication,andwhatbonds? base bond to calculate gametes, phenotype, genotype --> formulas AaBbCc x AaBbCc. Frequency of aaBBCc? of aa? of BB? Cc? What type of allele is often detected as a distortion in segregation rations, where one class of expected progeny is missing? gene interactions in which an allele of one gene modifies or prevents expression of alleles of another gene is known as independent assortment predicts a 9:3:3:1 ratio with 4 phenotypes in F2 progeny. If alleles are epistatic, what would you predict a protein complex that encircles the DNA double helix and DNA polymerase to make sure that the DNA polymerase doesnt fall off while replicating DNA is replicated what does recombination occur?
