However, it is a myth that sheep cannot lamb without human assistance; many ewes give birth directly in pasture without aid. [8] Balancing ease of lambing with high productivity is one of the dilemmas of sheep breeding. [7] While the majority of births are relatively normal and do not require intervention, many complications may arise.
An adult female is referred to as a ewe (/ j uː / yoo), an intact male as a ram, occasionally a tup, a castrated male as a wether, and a young sheep as a lamb. Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. [ 1 ]
The tapeworm, being monecious, contains both male and female reproductive organs in an individual. Thus each proglottid is a complete reproductive unit. Moreover, one defining feature of the genus is that there are two sets of reproductive organs situated at lateral sides with the associated cirrus pouches and genital pores in each proglottid.
Ovis is a genus of mammals, part of the Caprinae subfamily of the ruminant family Bovidae. [1] Its seven highly sociable species are known as sheep or ovines. Domestic sheep are members of the genus, and are thought to be descended from the wild mouflon of central and southwest Asia.
This list of related male and female reproductive organs shows how the male and female reproductive organs and the development of the reproductive system are related, sharing a common developmental path. This makes them biological homologues. These organs differentiate into the respective sex organs in males and females.
Mob – a group or cohort of sheep of the same breed that have run together under similar environmental conditions since the previous shearing (in Australian Wool Classing). [1] Monorchid – a male mammal with only one descended testicle, the other being retained internally. Monorchid sheep are less fertile than full rams, but have leaner meat ...
A sex organ, also known as a reproductive organ, is a part of an organism that is involved in sexual reproduction. Sex organs constitute the primary sex characteristics of an organism. Sex organs are responsible for producing and transporting gametes , as well as facilitating fertilization and supporting the development and birth of offspring.
Monogamy: One male and one female have an exclusive mating relationship. The term "pair bonding" often implies this. This is associated with one-male, one-female group compositions. There are two types of monogamy: type 1, which is facultative, and type 2, which is obligate. Facultative monogamy occurs when there are very low densities in a ...
