SCIENTIFIC INQUIRY The diagram in quest ion 6 represents just a few of the chromosomes of a meiotic cell in a certain person. Assume the freckles gene is located at the locus marked F, and the hair-color gene is located at the locus marked H, both on the long chromosome. The individual from whom this cell was taken has inherited different alleles for each gene ("freckles" and "black hair" from one parent, and "no freckles" and "blond hair" from the other). Predict allele combinations in the gametes resulting from this meiotic event. (It will help if you draw out the rest of meiosis and label the alleles by name.) List other possible combinations of these alleles in this individual’s gametes.

- 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. After meiosis is complete, how many chromatids and chromosomes will be present in one of the four progeny cells?arrow_forwardMeiosis Explains Mendels Results: Genes Are on Chromosomes Discuss the pertinent features of meiosis that provide a physical correlate to Mendels abstract genetic laws of random segregation and independent assortment.arrow_forwardThe chromosome constitution number of this individual is 2=6.

- Meiosis DrawingIn this assignment you will track and draw the chromosomes of a diploid organism through all the stages of meiosis. Make sure you label the alleles for genes on the chromosomes the whole way through - every chromatid should have labeled alleles. For meiosis, both crossing over and independent assortment can occur. For the purpose of this exercise, assume that there is a single crossover event on the long chromosome between the A and D genes. Only show crossing over after its fully occured. There are no crossover events on the short chromosome. Regarding independent assortment, there are two possible outcomes in meiosis if there are two homologous pairs of chromsomes. Include both independent assortment possibilities - one on the left side and one on the right. Fill in the possible gamete genotypes for each outcome. If you do this correctly you should end up with 8 different types of gametes.arrow_forwardThe drawings below represent four possible cells produce by meiosis in a cell pf the genotype AaBb. Examine the figures below and answer the questions that follow: 1. How many different types of cells are produced at the end of Meiosis I? A *Write your answer as a word, not a number 2. Is there any other way you could have arranged the chromosomes? For example, a. Could A and a be arranged so that both go to the same cell after Metaphase I (Yes/No)? B b. Could B and b be arranged so that both go to the same cell after Metaphase I (Yes.No)? C c. Could A and B be arranged so that both go to the same cell after Metaphase I (Yes/No)? D d. Could A and b be arranged so that both go to the same cell after Metaphase I?(Yes./No) E 3. Are the daughter cells haploid, or diploid? F 4. Do the daughter cells have the same genetic composition as the original cell (Yes/No)? G 5.

- 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.

- In human spermatogenesis, mitosis of a stem cell gives rise to one cell that remains a stem cell and one cell that becomes a spermatogonium. Draw four rounds of mitosis for a stem cell and label; the daughter cells. For one spermatogonium, draw the cells it would produce from one round of mitosis followed by meiosis. Label the cells, and label mitosis and meiosis. What would happen if stem cells divided like spermatogonia?arrow_forwardDuring zygotene stage of meiosis I, a remarkable pairing of chromosomes occurs. Look at the bottom part of As shown in which “mitosis: growth of the body” has produced cells with four different types of chromosomes. The black ones came from the sperm nucleus. The red ones came from the egg nucleus. If one of these nuclei were to undergo meiosis, which chromosomeswould pair during zygotene (which are homologous)— the long black one with the short black one or the long black one with the long red one?arrow_forwardGerm cells are specialized cells that develop into gametes. Gametes are produced through the process of meiosis. If the haploid number for monkeys is 27 chromosomes, how many chromosomes does a cell undergoing division have at each of the following phases?
