In the F1 generation the males were horned, the females hornless. Here, with regard to the horned character, both sexes were of the same genetic composition, i.e. heterozygous, or if we represent the possession of horns by H, and their absence by h, both sexes were Hh.
Murie on the Otaria, 'Proceedings Zoological Society, 1869, p. 108. Mr. R. Brown on the P. groenlandica, ibid. 1868, p. 417. With Ruminants sexual differences of colour occur more commonly than in any other order. We have seen that in this species the crests and tufts of hair are likewise more developed in the male than in the hornless female. I am informed by Mr.
For the first half-hour it seemed as if the dominion of the cattle-man had ended, but as the swift car drew away from the valley of the Bear and climbed the divide toward the north, the free range was disclosed, with few changes, save in the cattle, which were all of the harmless or hornless variety, appearing tame and spiritless in comparison with the old-time half-wild broad-horn breeds.
In Europe and Asia the opossums lived on lustily, in spite of competition, during the whole of the Eocene period, side by side with hog-like creatures not yet perfectly piggish, with nondescript animals, half horse half tapir, and with hornless forms of deer and antelopes, unprovided, so far, with the first rudiment of budding antlers.
A still more ancient progenitor probably somewhat resembled the Hyomoschus aquaticus for this animal is spotted, and the hornless males have large exserted canine teeth, of which some few true deer still retain rudiments.
Generally, the most vigorous males, those which are best fitted for their places in nature, will leave most progeny. But in many cases, victory will depend not on general vigour, but on having special weapons, confined to the male sex. A hornless stag or spurless cock would have a poor chance of leaving offspring.
Similarly we observe that special kinds of cows, as e.g. hornless ones, are designated by the term 'cow, since the quality of possessing the generic character of cows is met with everywhere in connexion with the essential character of such animals with mutilated horns; since in fact that quality contributes to define their essential character.
They were, in many cases, supposed to belong to the Galloway breed; or, which is more likely, to the Suffolk dun, a variety of the Galloway, and a far better milking stock than the Galloways, from which, it sprung. These polled, or hornless cattle vary in color and qualities, but they are usually very good milkers when well kept, and many of them fatten well, and attain good weight.
On the way back to the house they had an adventure, a sort of adventure, and it brought home to Betsy once for all how much she loved dear, sweet Aunt Frances, and just what kind of love it was. As they crossed the barnyard the calf approached them playfully, leaping stiff-legged into the air, and making a pretense of butting at them with its hornless young head.
'All my news is that I am seeking service, answered Ardan son of Gorla; 'I have come from far since sunrise, and glad was I to see the rays of your lamp stream into the darkness. 'I need someone to herd my three dun cows, which are hornless, said the old man.
