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?

Question 24 (2 points) Mendel's law of segregation can be explained by a specific event that occurs during meiosis. That event is V 1) homologous chromosomes synapse and cross over during Prophase 2) independent assortment of homologous chromosomes at Metaphase I 3) random fertilization 4) sister chromatids separate during Anaphase II 5) homologous chromosomes separate during Anaphasel

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

FLUID o True False 1 pts Question 3 Which of the following statements about MEIOSIS are CORRECT? Only haploid cells are produced Sister chromatids are separated during anaphase I and homologous chromosomes are separated during anaphase II After crossing over (recombination) the sister chromatids are still identical There are two rounds of cell division following only one round of DNA synthesis non-disjunction can occur during either anaphase I or Il 1 pts Question 4

Which of the following is not one of the ways that meiosis can introduce variability into a population via sexual reproduction? meiosis never introduces genetic variation production of diploid gametes independent assortment along the metaphase plate crossing over random fertilization The role of meiosis in Mendel's law of segregation is that it allows crossing over to occur. it allows genes to be duplicated. it separates sister chromatids and exact copies of genes it separates homologous chromosomes and therefore gene alleles...
