There are two types of spermatocytes, primary and secondary spermatocytes (Figure 1). Primary and secondary spermatocytes are ... Each secondary spermatocyte will form two spermatids after Meiosis II. Although spermatocytes that divide mitotically and ... After Meiosis I, two secondary spermatocytes are formed. Secondary spermatocytes are haploid (N) cells that contain half the ...
