2. A diploid cell contains two pairs of chromosomes, which we will call 1 and 2. Assume chromosome! is clearly larger than chromosome 2. Each chromosome pair contains a maternal and a paternal member (e.g. 1 and 1 & 2 and 2"). An allele called G is localized to 1" whereas an allele called g is on chromosome 1P. Allele R is localized to 2m whereas alleler is localized to 2. Using these designations and clearly drawn and labeled chromosomes,...

The figure below shows chromosomes in a cell produced by some organism. Letters represent different kinds of genes; upper/lowercase letters represent different alleles for the same gene: e.g., purple allele (P) vs. white allele (p) for a flower color gene. 1. How many chromosomes do you see? 2. As drawn, is this cell haploid or diploid? 3. On what did you...

Crossing-Over in Meiosis Meiosis is a process of nuclear division that reduces the number of chromosomes in new cells to half the number in the original cell. The parent cell is diploid (2n), and it begins meiosis with a replicated set of chromosomes. During meiosis, this parent cell Homologou will divide twice to create four haploid (1n) cells. pairs During prophase I of meiosis I, homologous pairs of chromosomes pair up and stick together to form tetrads through the process...

1. Represent all chromosomes in a 2n = 4 cell before replication. Number the homologous chromosomes as you would in a karyotype (e.g., Chromosome 1, Chromosome 2). 2. Gene F is on Chromosome 1 and gene G is on Chromosome 2. This cell carries two different alleles of gene F (called F and f), and two different alleles of gene G (called G and g). Label these alleles on the unreplicated chromosomes that you drew above. 3. In the space...

3. (4 pts). A diploid somatic cell of a hypothetical eukaryote contains two pairs of homologs in its nucleus (2N = 4). One pair of homologs is metacentric and the other pair is submetacentric. The metacentric pair is heterozygous at two gene loci and each locus is on a different arm. At one locus, the alleles are identified by the letters “A” and “a”. At the other locus, the alleles are identified by the letters “B” and “b”. The upper...
2. Which of the following occurs during mitosis but not during meiosis I?
2. Which of the following occurs during mitosis but not during meiosis I? a. The chromosomes are pulled to opposite poles of the spindle apparatus. b. The chromatids of each chromosome are separated. c. The nuclear envelope breaks down. d. Both synapsis and crossing over take place. e. The diploid number of chromosomes is reduced to the haploid number.3. Table 1 shows the stage and number of cells and chromosomes per cell at the end of the stage in a 2n - 24 organism. u...

Nameindulia Los Drosophila Genetics Predictions-L113 (20 pts.) Part I. Meiosis and Punnett Squares Remember, whenever you use Punnett Squares to solve genetics problems, be sure you are completing each of the following steps: 1) Identify the genotypes of the parents. 2) For the specific traits of interest, figure out what kinds of haploid gametes each parent can make. In each gamete, there should be one allele for each trait of interest. If there is more than one trait, make sure...
