Question

Hisardale is obtained by crossing
A) Merino ewes with Bikaneri Rams
B) Bikaneri ewes with Merino Rams
C) Horse with Donkey
D) Superior Bull with superior Cow

Answer 1

Hint:In biotechnology, hybrids are the major application which mainly aims at improving the yield. Cross-breeding is the process where the breeding between the two individuals of different species takes place. In this system, a different variety of individuals can be identified.

Complete answer:
Let’s discuss the given options and find the correct answer.
>Merino ewes with Bikaneri Rams: this statement is wrong because Hissardale is a new breed of sheep developed in Punjab by crossing Bikaneri ewes and Merino rams not by crossing Merino ewes with Bikaneri Rams. hence option A is incorrect.
>Bikaneri ewes with Marino Rams:Hissardale is a new breed of sheep which was developed in Punjab by crossing Bikaneri ewes and Merino rams. Hence option B is correct.
>Horse with Donkey: A mule is produced by the interspecific hybridisation between male donkey and a female horse (mare). In interspecific hybridisation, male and female animals of two different related species are mated. In some cases, the progeny may combine desirable features of both the parents, and may be of considerable economic value. Hence option C is incorrect.
>Superior Bull with superior Cow:Superior males and superior females of the same breed are identified and mated in pairs. In case of cattle, a superior female is the cow or buffalo produces more milk per lactation and a superior male is the bull which gives rise to superior progeny as compared to those of other males. Hence option D is incorrect.

Hence, The option B: Bikaneri ewes with Marino Rams is the correct answer.

Note:Mating of superior male of one breed and superior female of another breed is called cross breeding. Desirable qualities of two breeds can be combined by this process.
