Most offspring were from monogamous pairs, but a few cases consistent with polygyny by males or sequential polyandry by females were also found. |
For instance, in the practice of polygyny, each wife is typically allotted her own house, most often within the same compound as the other wives but sometimes elsewhere. |
In the past Coras practiced polygyny, with a man marrying several sisters, but this practice is dying out. |
These days, polygyny is achieved in Western culture through serial monogamy. |
However, the degree of dimorphism in some clades of mammals, including perissodactyls, does not correlate with the degree of polygyny. |
Polygyny is legal, and couples have the option of choosing between monogamy and polygyny when they enter into a civil marriage. |
