Question 24 (2 points) Mendel's law of segregation can be explained by a specific event that...
Question 12 (2 points) Which of the following events of meiosis leads to the creation of haploid cells by the end of Telophase 1 of meiosis? 1) sister chromatids separate during Anaphase II 2) homologous chromosomes synapse and cross over during Prophase 3) homologous chromosomes separate during Anaphase 4) random fertilization 5) nondisjunction
Recall Mendel's law of segregation for autosomal alleles D and d and consider the behavior of homologous chromosomes in meiosis. During which stage of M phase do these two alleles segregate from one another? (Assume no crossovers between homologs.) - prophase I - anaphase I - metaphase I - telephase I
QUESTION 14 Which of the following behaviors of melotic chromosomes is responsible for Mendel's law of segregation? OCondensation of chromosomes during metaphase 1 OSegregation of homologous chromosomes during anaphase OSegregation of sister chromatids during anaphase I O DNA replication in interphase OPairing of homologous chromosomes in prophase QUESTION 15 Which of the tolowing best explains why some autosoma trisomies, such as trisomy 21, are viable in humans, while others die as very early embryos? O The extra gene dosage of...

alagy and Early Develapment Leberatory 2. Identify Homologous Chromosomes and Sister Chromatids in appropriate phases. What are homologous chromosomes? Are they present in all cells? If not, which cells lack homologous chromosomes? Are they present in all stages of mitosis? Are they present in all stages of Meiosis 1? Meiosis II? How do the terms haploid and diploid relate to the presence/absence of homologous chromosomes? What are sister chromatids? During what phase of the cell cycle do sister chromatids form?...
Please let me know which of the following are right from question 1&2 1)What is the most likely phenotype of a loss of function mutation in a proto-oncogene? (you may select more than one answer) Increased cell division, decreased cell division, cancer, non-disjunction QUESTION 2 Which of the following behaviors of meiotic chromosomes is responsible for Mendel's law of segregation? Condensation of chromosomes during metaphase 1 Segregation of homologous chromosomes during anaphase chromatids DNA replication in interphase Pairing of homologous...
Simulate meiosis by drawing One pair of chromosomes and no crossing over Instructions: Set up your cell. The cell you start with should be: A diploid cell It should contain 1 pair of homologous chromosomes It should be in G1 of the cell cycle, before DNA replication occurs Be sure to show 2 genes that are both heterozygous . Go through the steps of meiosis. Be sure to show and label these in your pictures: Label homologous chromosomes and sister...
