The mitotic chromosomes of a macropod hybrid

Abstract

In a yard at Hermitage Research Station, Warwick, a male agile wallaby (Wallabia agilis (Gould)) was observed mating with two female red kangaroos (Megaleia rufa (Desmarest)) and by late 1970 these females were carrying furred pouch young of phenotypic appearance intermediate between the species. A mitotic chromosome count of 2n = 18 was obtained for both progeny, male and female, of Wallabia agilis (Gould), (2n = 16) x Megaleia rufa (Desmarest), (2n = 20).
