Answer:
Disease resistant traits and selective breeding.
Explanation:
Disease resistant traits in wild plants and animals are helpful if these traits are present in our plants and animals in order to maintain its high quality. We can modify both our meat and plants with the help of selective breeding of high quality plants and animals. Due to selective breeding, we can achieve the desired characteristics through modification in our plants and animals.

Answer:
The correct answer would be zygote...blastocyst...embryo...fetus.
The fertilization of sperm and egg results in the formation of zygote. It receives genetic material from a male as well as a female parent.
It divides with the help of mitotic divisions and results in the formation of 2, 4, 8, and 16 celled stages.
It results in the formation of the hollow spherical ball of cells termed as a blastocyst. The cells are distributed to form the outer layer termed trophoblast and inner cell mass which gives rise to the embryo.
Trophoblast help in the implantation of the blastocyst into the uterine wall.
The cells of the embryo undergo organogenesis during different organs such as heart, brain, lungs et cetera are formed.
In humans, almost 9 weeks after the fertilization the developing embryo is considered a fetus.
The fetus development continues until birth.
