5  | 
    Clearly    identifies all prenatal development, including where the events are occurring.    This includes fertilization and implantation.  | 
    Identifies    three factors that affect embryonic and fetal development structures—one of    each chromosomal, hormonal, and environmental.  | 
    Clearly    explains parturition events.   | 
    Fully    describes hormonal and nerve control of lactation.  | 
    Fully    describes each reproductive technology that assists in enhancing reproductive    potential, reducing reproductive potential, and monitoring embryonic or fetal    development.  | 
  
4  | 
    Clearly    identifies most prenatal development and includes where the events are occurring.    This includes fertilization and implantation.  | 
    Identifies    three factors that affect embryonic and fetal development structures—one of    each chromosomal, hormonal, and environmental.  | 
    Clearly    explains parturition events.   | 
    Describes    hormonal and nerve control of lactation.  | 
    Describes    a reproductive technology that assists in enhancing reproductive potential,    reducing reproductive potential, and monitoring embryonic or fetal    development.  | 
  
3  | 
    Identifies    some prenatal development and includes where the events are occurring. This    includes fertilization and implantation.  | 
    Identifies    two factors that affect embryonic and fetal development structures—two    of either chromosomal, hormonal, or environmental.  | 
    Explains    some of the parturition events.   | 
    Describes    only hormonal, not nerve, control of lactation.  | 
    Describes    only two of the following reproductive technologies that assist in enhancing    reproductive potential, reducing reproductive potential, and monitoring    embryonic or fetal development.  | 
  
2  | 
    Lacking    much detail of prenatal development, does not include where the events    are occurring.  | 
    Identifies    two factors that affect embryonic and fetal development structures—two    of  either chromosomal, hormonal, or environmental.  | 
    Names    only the parturition events.   | 
    Describes    only some of the hormonal control of lactation, does not describe    nerve control of lactation.  | 
    Describes    only two of the following reproductive technologies that assist in enhancing    reproductive potential, reducing reproductive potential, and monitoring    embryonic or fetal development.  |
