Thread: Varying foetus' size

  1. #1

    Varying foetus' size

    It is noticeable the large variance in foetus' sizes between Roe females at any particular point of the season. Does the variance relate to when the mating took place, or when the embryo implanted? i.e. is the period between fertilisation and parturation constant within a day or two?

    What species you talking about? Remember Roe have delayed implantation.

    ??? The question does mention both roe and delayed implantation.

    My mistake. Why should young be the same size?

    The embryo has an 'embryonic clock' and decides itself when to implant into the second stage of pregnancy. Tells you all about it here:
