Answer 1

Answer:

1 is the not the true statement

Answer 2

Artificial selection is also called as selective breeding

Explanation:

• (a) artificial selection is the selection of particular character from wild species to the next generation here particular allele and genes are selected which are beneficial for us . artificial selection is also known as selective breeding it can be done in animals and plants both  .

• (IV) is wrong statement about micro evolution.

• ( C) Micro evolution has been discussed above and artificial selection process which leads to evolution is also discussed above in the given passage.

• (d) Different breeds are having different alleles the slected alleles for artificial selection is wild type
