Which of the following is an incorrect statement?a)Mule and hinny are...
Explanation:
The incorrect statement is D) Hisardale is a cross-breed produced by mating Marino ewes and Bikaneri rams. This statement is incorrect because Hisardale is actually a cross-breed produced by mating Bikaneri ewes and Marino rams.
Let us understand the other options mentioned in the question:
A) Mule and hinny are examples of interspecific hybridization: This statement is correct. A mule is produced by mating a male donkey with a female horse, while a hinny is produced by mating a male horse with a female donkey. Both mule and hinny are sterile, as they have an odd number of chromosomes.
B) MOET is used to increase the herd size in cattle: This statement is correct. MOET stands for Multiple Ovulation and Embryo Transfer. It is a reproductive technology that allows the production of a large number of offspring from a genetically superior female. MOET is used to increase the herd size in cattle, by producing multiple embryos from a single cow.
C) Inbreeding depression is overcome by a single outcross: This statement is incorrect. Inbreeding depression is a phenomenon where the offspring of closely related individuals exhibit reduced fitness. It occurs due to the accumulation of deleterious recessive alleles in the population. Inbreeding depression can be overcome by introducing genetic diversity into the population through multiple outcrosses, rather than a single outcross.
Therefore, the correct answer is D) Hisardale is a cross-breed produced by mating Marino ewes and Bikaneri rams.
Which of the following is an incorrect statement?a)Mule and hinny are...
A cross between members of the different breeds of the same species is called cross-breeding. This allows the desirable qualities of two different breeds to be combined. Hisardale is such a breed of sheep developed in Punjab by cross-breeding Marino ram and Bikaneri ewe. Bikaneri ewes are known as the only lustrous carpet wool-producing breed. The Marino rams are among the most relevant and economical breeds of sheep, much prized for their wool.
