Question 1 Which of the following behaviors of chromosomes explains Mendel's first law (law of segregation)? Two different genes will randomly assort their alleles during the process that gives rise to gametes. Homologous chromosomes separate (segregate) from each other during Meiosis I The two copies of a gene segregate (or separate) from each other during the process that gives rise to gametes. Sister chromatids separate (segregate) from each other during Meiosis II The segregation of each pair of homologous chromosomes during meiosis I is an independent event The segregation of each pair of sister chromatids during meiosis II is an independent event Homologous chromosomes separate (segregate) from each other during MeiosisI

Singular versus plural is a clue that will help you pick the right roman numeral. homologous chromosomes line up next to each other as tetrads along the mid- line of the cell DNA condenses, tetrads form as homologous chromosomes come together and exchange DNA parts in crossing over, nuclear membrane disintegrates A. Early Interphase B. Late Interphase one of each homologous pair reaches the end of the cell, new nuclear membranes form, and the cell membrane begins to pinch in C. Prophase I v DNA condenses in two cells, nuclear membranes disintegrate D. Metaphase I the copies of the chromosomes (daughter chromosomes formerly known as sister chromatids) split apart and move towards the ends of two cells E.

Meiosis Explains Mendels Results: Genes Are on Chromosomes The following diagram shows a hypothetical diploid cell. The recessive allele for albinism is represented by a, and d represents the recessive allele for deafness. The normal alleles for these conditions are represented by A and D, respectively. a. According to the principle of segregation, what is segregating in this cell? b. According to Mendels principle of independent assortment, what is independently assorting in this cell? c. How many chromatids are in this cell? d. Write the genotype of the individual from whom this cell was taken. e. What is the phenotype of this individual? f. What stage of cell division is represented by this cell (prophase, metaphase, anaphase, or telophase of meiosis I, meiosis II, or mitosis)? g.
