Stuck Sperm Cells lining the epididymis secrete a glycoprotein (beta-defensin) that coats sperm and facilitates their passage through cervical mucus. There are two common alleles for human beta-defensin: a wild-type allele (wt) and an allele with a deletion (del). To find out if this genetic variation could affect fertility, Gary Cherr and his colleagues tested the ability of sperm from men with different genotypes to pass through a gel barrier. The barrier was designed to simulate cenrical mucus. The researchers placed sperm on one side of the gel, then used a video camera to record how many passed into the gel over time. FIGURE 41.12 illustrates their results. FIGURE 41.12 Effect of beta defensin genotype on the ability of sperm to penetrate a gel that simulates cervical mucus. Sperm from 16 men was tested: 4wt/wt, 6wt/del, and 6 del/del. Fresh sperm were placed on one side of the gel, and a video camera was focused on a region 2.75 mm into the gel. The number of sperm in this region was recorded at one-minute intervals for six minutes. Sperm numbers shown are averages. Bars indicate range. After four minutes, how many sperm from men with a wild-type allele were in the camera's view an average?

Which statement is most correct regarding the difference between mitosis and meiosis? O Meiosis can produce any cell type, while mitosis can only make gametes (sperm/egg cells) * 1 p Mitosis essentially clones a cell (makes an identical copy), while meioisis is a more O complex process that divides up a cell's set of chromosomes into gametes (sperm/egg cells) ODNA replication is required for mitosis but not for meiosis Dyads are seen in mitosis but not meiosis
Women sometimes develop benign tumors calledovarian teratomas or dermoid cysts in their ovaries.Such a tumor begins when a primary oocyte escapesfrom its prophase I arrest and finishes meiosis Iwithin the ovary. (Normally meiosis I does not finish until the primary oocyte is expelled from theovary upon ovulation.) The secondary oocyte thendevelops as if it were an embryo. Development isdisorganized, however, and results in a tumorcontaining differentiated diploid tissues, includingteeth, hair, bone, muscle, and nerve. If a dermoidcyst forms in a woman whose genotype is Aa, whatare the possible genotypes of the cyst, assuming norecombination?
