- Two haploid yeast with the genotypes HIS4 LEU2 LYS2 and his4 leu2 lys2 were mated to produce diploid yeast. Next, the resulting diploid yeast went through meiosis and formed haploid spores. Read the 4 statements below. For each statement, either put “yes” if you agree with it or put “no” if you don’t. Explain your logic. yes/no 1. Half of the spores will be His+ and half will be His- 2. Half of the spores will be Leu+ and half will be Leu- 3. Half of the spores will be Lys+ and half will be Lys- 4. Half of the spores will be His+ Leu+ Lys+ and half will be His- Leu- Lys-arrow_forwardUse the following information as the basis for answering all questions: A diploid eukaryotic organism has 4 unique chromosomes. Chromosome I is metacentric, chromosome II is telocentric, chromosome III is a submetacentric, and chromosome IV is acrocentric. 16. How many total chromosomes are in a germ cell in the ovary of this organism that is in Metaphase of Meiosis I? 17. How many total chromatids are in a germ cell in the ovary of this organism that is in Metaphase of Meiosis I? 18. How many total telomeres are in a germ cell in the ovary of this organism that is in Metaphase of Meiosis I?19. How many total chromosomes are in a germ cell in the ovary of this organism that is in Anaphase of Meiosis I? 20. How many total chromatids are in a germ cell in the ovary of this organism that is in Anaphase of Meiosis I? 21. How many total telomeres are in a germ cell in the ovary of this organism that is in Anaphase of Meiosis I?arrow_forwardWhich of the following is true in comparing a cell's genetic information at the beginning of Meiosis II towards the end of Meiosis II? O It has twice the DNA of the cell that began meiosis. O It has one-fourth the DNA and one-half the chromosomes as the cell that began meiosis II. O It has the same amount of DNA at the beginning and end of Meiosis II It has half the amount of DNA as the cell that began meiosis.arrow_forward

The resulting zygotes undergo meiotic and then mitotic division to produce asci with eight ascospores. The ascospores in the asci are ordered and reflect the position of the parental nuclei in the zygote. Use the passage to answer the question. Based on the diagram, how many unique ascospores are produced in each ascus resulting from the cross fertilization of two Ascomycetes fungi? A. 1 B. 2 C. 4 D. 8arrow_forward

Mutations that occur during this process would ALWAYS be passed on to the next generation Neither mitosis nor meiosis Both mitosis and meiosis Meiosis only Mitosis onlyarrow_forwardSelect all the true statements about the cell in the drawing. Group of answer choices 1. this cell is haploid 2. this cell has 3 chromosomes 3. this cell is diploid 4. this cell has unduplicated chromosomes 5. this cell has 3 homologous pairs 6. this cell has 6 chromosomes 7. this cell has 12 chromosomes 8. this cell has duplicated chromosomes 9. this cell has 6 homologous pairs 10. this cell has no homologous pairsarrow_forwardWhich of the following differentiates meiosis from mitosis? mitosis is used for the repair of cells, whereas meiosis creates cells for sexual reproduction. In mitosis four identical daughter cells are produced, whereas two genetically different cells are produced in meiosis meiosis is a form of asexual division, whereas mitosis is a form of sexual division mitosis occurs in prokaryotic cells, whereas meiosis occurs in eukaryotic cellsarrow_forward
