in the experiment of following chromosomal dna mvement througgh meiosis, why. do you use non-sister chromatids to demobstrate crossing over? what combinatiobns of alleles could result from a crossover between BD and bd chromosomes? Identify two ways that meiosis contributes to genetic recombination. Why is it necessary to reduce the number of chromosomes in gametes, but not in other cell?
11. Refer to the figure showing a cell with two pairs of homologous chromosomes in prophase I of meiosis. Genes A (alleles A and a) and D (alleles D and d) are located on the longer pair of chromosomes, and gene B (alleles B and b) is located on the shorter pair. BOOB centromere DoD dood 2 chromatids = chromosome How many different combinations of A, B and D alleles are possible in the genotypes of the daughter cells produced from this cell? O 16 8. O O O O
2. In the cells below, draw the two possible arrangements of Abdul's sex chromosomes and the homologous pair of autosomes carrying the gene controlling albinism at metaphase l of meiosis. Ignore the possibility of crossing-over but do show the alleles on each chromatid in your drawing. Be sure to differentiate the autosomes from the sex chromosomes, and draw the sex chromosomes accurately (do not just write "X" and "Y"). 00
14.Each individual chromosome is composed of _______ 15.The exchange of genetic material between homologous chromosomes during crossing-over is: 16. Matching: If a cell has a diploid number of 10 (2n=10), how many chromosomes will be present in each of the following situations (answers can be used more than once). Group of answer choices How many in a set (n)? How many after mitosis (diploid)? How many after meiosis (haploid)?
Which of the following shows differences between chromosome in a cell at metaphase of mitosis with those in a cell at metaphase Il of meiosis? * I The chromosomes in metaphase of mitosis can be diploid but the chromosomes in metaphase II of meiosis always consist of a haploid set. In metaphase of mitosis, sister chromatids of each chromosome are genetically identical but in metaphase II of meiosis sister chromatids are not genetically identical. II III Individual chromosomes line up at the metaphase plate during metaphase of mitosis, but pairs of homologous chromosomes line up at metaphase plate during metaphase II of meiosis. O I and II only O I and II only Il and III only O I, Il and III
The segregation of chromosomes in cell division is a result of O the random way each pair of homologous chromosomes lines up at the metaphase plate during meiosis I O the random distribution of the sister chromatids to the two daughter cells during meiosis II O the random nature of the fertilization of ova by sperm O the random distribution of the homologous chromosomes to the two daughter cells during meiosis II O the random exchange of genetic material between homologous chromosomes
