5. If concerned about one trait (like sickle cell or cystic fibrosis) and the genotype of the pe offapsing or at oan e ed to determine the probability of thephenotpe of any unborn A. Testcross Punnett square Pedigree D. Karyotype 6. Sister chromatids are a. separating during prophase of mitosis c composed of RNA 7. Cells that reproduce through the process of binary fission are a. reproducing sexually b. eukaryotes d. going through meiosis 8. Eukaryotic cells spend most of their cell cycle in this stage. a. prophase b. interphase c. metaphase d. telophase 9. During which phase of mitosis do the chromosomes line up on in the center of the celil? a. anaphase b. telophase d. metaphase 10. Two chromosomes in a nucleus that carry alleles for the same trait in the same positions on the chromosomes but specify different versions of some traits constitute a pair of a. homologous chromosomes b. sister chromosomes c. complementary chromosomes d. heterologous chromosomesExplanation / Answer
Answer 5) Punnett square in genetics is a square diagram through which one can predict the possible outcome of a cross. So if the genotype of parents is known and one focus is on one trait then the phenotype of offspring’s can be predicted.
Answer 6) during the cell division cycle, in metaphase sister chromatids are aligned at metaphase plate which are then separated in anaphase.
Answer 7) Binary fission is from of asexual reproduction which is prevalent in prokaryotes.
Answer 8) Eukaryotic cell mostly spend their time in interphase where they perform necessary function and prepare for the cell division in mitotic phase.
Answer 9) During metaphase stage, the chromosomes line up on the metaphase plate formed at the center.
Answer 10) Homologous chromosomes are the pair of chromosomes each derived from different parent, one from mother and one from father. Homologous chromosomes have same gene at the same loci but with different alleles.
