Biol 180 - Exam 1 [3/9 ]QUIZ TEST MOD 004 with Verified Answers 2023

pure line correct answers In genetics, a strain that produces offspring identical to the parents when self-fertilized or mated within the strain. Pure lines are homozygous for the gene under study. hybrid correct answers the offspring of parents from two different strains, populations, or species parental generation correct answers the adults used in the first experimental cross of a breeding environment F1 generation correct answers first filial generation. The first generation of offspring produced from a mating (i.e., the offspring of the parental generation) monohybrid cross correct answers a mating between two parents that are both heterozygous for one given gene recessive correct answers referring to an allele whose phenotypic effect is observed only in homozygous individuals dominant correct answers referring to an allele that determines the same phenotype when it is present in homozygous or heterozygous form reciprocal cross correct answers a cross in which the mother's and father's phenotypes are the reverse of those examined in a previous cross particulate inheritance correct answers the concept that inheritance is based on genes that do not blend together in offspring but instead remain separate or particle-like gene correct answers (1) In a molecular context, a section of DNA (or RNA, for some viruses) that contains the regulatory sequences and coding information for the transcription of one or more related functional RNA molecules, some of which encode polypeptides. (2) In Mendelian genetics, the hereditary determinant of a trait, such as flower color or seed shape in pea plants allele correct answers a particular version of a gene genotype correct answers all the alleles of a gene or genes present in a given individual principle of segregation correct answers the concept that each pair of hereditary elements (consisting of alleles of the same gene) separate from each other during meiosis. One of Mendel's two principles of genetics homozygous correct answers having two identical alleles of a gene heterozygous correct answers having two different alleles of a gene
