Answer:
D) Beta galactosidase will not be produced.
Explanation:
Promoter is necessary to start the transcription of the structural gene. The position of promoter is important because the gene which is downstream to promoter will be transcribed and the gene upstream to the promoter will not be transcribed.
Lac operon has three structural gene lacZ, lacY, and lacA. Lac Z codes for β galactosidase, lac Z codes for permease and Lac A codes for transacetylase. So if promoter for the lac operon moves between the beta-galactosidase (lacz) gene and the permease (lacy) gene, then the beta-galactosidase gene will not be produced because it is places upstreamed to the promoter.
Answer:
Selective breeding combines ideal traits of animals to replicate in offspring
Explanation:
Selective breeding is the process which involves choosing parents with particular characteristics to breed together and produce offspring with more desirable characteristics. It is also known as artificial breeding and provides both plants and animals with greater variation and higher chances of survival. Selective breeding can be used to produce plants with bigger and tastier fruits and vegetables, crops with greater resistance to pests and diseases, and bigger animals that can be used for meat or milk production. The process of selective breeding is of great importance to the farmer today as it has brought about greater economic advantages.
In the instance of the black-breed boar and the white-breed sow being matched for mating, the reason is to combine these desirable traits in their offspring. The black-breed boar produces quality meat while the white-breed sow has quality fertility. Mating between these two breeds will produce offspring which has both traits of quality meat production as well as quality fertility.
