Examples

  • When a spermatogonium was observed to change to a primary spermatocyte-still diploid-it would be segregated and at the instant it divided into two secondary spermatocytes-haploids, one with an X chromosome and one with a Y chromosome-they would be again segregated and each would be encouraged to develop into spermatozoa. \par
