Genetical and embryological comparison of two mutations which cause foetal blebs in mice

Abstract

SUMMARYMutants with abnormalities which were the consequence of the formation of haematomas during gestation were designated as ‘foetal haematomata’ (fh). Thefhhomozygotes were found to be morphologically and embryologically very similar to myelencephalic bleb (my) mice. It was also found, however, that thefhandmymutants were separate genetic entities due to two independently segregating recessive genes.
