One advantage of having a cloned flock

Answers

Answer:

Producing transgenic animals has practical advantages, such as using less than half of experimental animals for the production of an envelope.

Explanation:

Currently it is only possible to add genes, the transgenic sheep that exist are found to produce human proteins. However, it is convenient for some proteins to remove endogenous proteins from milk. For example, for human serum albumin.

There is a high demand for some human proteins for the treatment of various diseases. Small quantities can be produced in cell cultures but the cost is very high. Higher amounts can be made by bacteria or yeasts, but proteins are difficult to purify and that is why some of the advantages of having transgenic animals is the amount of protein produced.

it eliminates certain genetic diseases or bad traits for the flock.

c to determine mating patterns in organisms
d to identify traits that are acquired during an organism’s life

Answers

The pedigree's purpose is to understand patterns of inheritance in organism. Examination of the pedigree utilizing the standards of Mendelian legacy can decide if a characteristic has an overwhelming or passive example of legacy. Families are frequently built after a relative harrowed with a hereditary issue has been distinguished.

The purpose of pedigree is to trace the ancestory. Therefore, the correct answer is B, i.e., to understand the patterns of inheritance in organisms. it helps in knowing that what characters are passed to the offsprings, what disease may be transferred to the offsprings, and also the mode of inheritance of the disease.
