The polled trait is far more common in beef breeds than in dairy breeds. CRISPR technology is being developed to create polled versions of dairy breeds. [5] In sheep, the allele for horns in both sexes is partially dominant to the allele for being polled in both sexes, and both of these are dominant to that for polling in the female only. [6]
The Gerudo race is a matriarchal society of warriors that is almost exclusively female, with the only exception being that a male Gerudo is born every 100 years, who then becomes their leader. [ 2 ] [ 3 ] Their tendency to bar interaction with men is due to the belief that it will lead to disaster, with the only male interaction allowed being ...
Often, mentions of dams imply cows which will be kept in the herd for repeated breeding (as opposed to heifers or cows to be sold off sooner). A young female before she has had a calf of her own [2] and who is under three years of age is called a heifer (/ ˈ h ɛ f ər / HEF-ər). [3] A young female cow that has had only one calf is ...
Before 1790, beef cattle averaged only 160 kg (350 lb) net. Thereafter, weights climbed steadily. [8] [9] Cattle breeds vary widely in size; the tallest and heaviest is the Chianina, where a mature bull may be up to 1.8 m (5 ft 11 in) at the shoulder, and may reach 1,280 kg (2,820 lb) in weight.

For example, in livestock breeding, breeders may use inbreeding when trying to establish a new and desirable trait in the stock and for producing distinct families within a breed, but will need to watch for undesirable characteristics in offspring, which can then be eliminated through further selective breeding or culling. Inbreeding also helps ...
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
The etymology of the term "freemartin" is uncertain: speculations include that "free" may indicate "willing" (referring to the freemartin's willingness to work) or "exempt from reproduction" (referring to its sterility, or to a farmer's decision to not bother trying to breed a freemartin, or both), or that it may be derived from a Flemish word for a cow which gives no milk and/or has ceased to ...
Gorilla Great reed warbler. When two animals mate, they both share an interest in the success of the offspring, though often to different extremes. Unless the male and female are perfectly monogamous, meaning that they mate for life and take no other partners, even after the original mate's death, the amount of parental care will vary. [7]
