Chapter 46, Problem 11TYU
SCIENTIFIC INQUIRY You discover a new egg-laying worm speties. You dlssect four adults and find both oocytes and sperm in each. Cells outside the gonad contain five chromosome pairs. Lacking genetie variants, explain how you would determine whether the worms can self-feriilize.

Assume the freckles gene is located at the locus markedF, and the hair-color gene is located at the locus marked H,both on the long chromosome. The individual from whomthis 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 combinationsin the gametes resulting from this meiotic event. (It will helpif you draw out the rest of meiosis and label the alleles byname.) List other possible combinations of these alleles in thisindividual’s gametes.arrow_forward

A. Cytokinesis occurs and separates the cytoplasm and its contents into daughter cells. B. Diploid gametes divide to form haploid daughter cells with unique genetic makeup. C. During interphase, homologous chromosomes are duplicated to form sister chromatids. D. Segments of DNA are exchanged between homologous chromosomes during crossing over.arrow_forwardmeiosis is a type of cell division only required in organisms that reproduce sexually. Explain why meiosis is needed (instead of mitosis) for sexual reproduction, and describe one possible advantage of reproducing sexually instead of just copying cells.arrow_forward
