Apples as we know them today did not always exist. All apple varieties available to us today are derived from the wild relative Malus sieversii which is indigenous to Kazakhstan. The Romans developed over 23 varieties which they brought with them to England, which then the British brought to the Americas. What process was used to derive all of the varieties of apples we have today?
A. Genomics and DNA sequencing.
B. Gene cloning and by using transgenics.
C. Genetic modification and genetic engineering.
D. Conventional breeding.
E. Inbreeding depression.

The correct answer is letter D. Conventional breeding

Explanation:

In conventional genetic improvement a plant is crossed with another of the same species, with no incorporation of genes from another organism into the plant's genome, requiring repeated crossings until reaching the desired improved cultivar. Only in transgenics or genetic engineering are genes from another organism incorporated into the plant's genome.

Option- (D)

The process which was used to derive all of the varieties of apples that we have today is the conventional form of breeding and that the different methods which are mentioned along with it are more advanced then the conventional form of plants breeding.

Explanation:

There different techniques are used by research workers and scientist to have better results and to have a variety of products for improving there health effects on humans.So, the conventional form of breeding involves those organisms which can get along easily and survive to produce more productive form of products.

Simulating adaptations in a species in this activity, you will discuss in detail the adaptations in a species of rain forest plants. you will build a simulation that explains the changes in the traits of the plant population over 10 years. you will also establish a scientific explanation to justify the changes in the traits of the population, * time to complete: 1-2 hours part a an organism's adaptations are specific to its native environment. an organism that lives in a coniferous forest will have different adaptations compared to an animal that lives in a tropical rain forest. the following graphs show the temperature and precipitation throughout the year for two different forests: a coniferous forest in canada, and a tropical rain forest in belize. evaluate the graphs, and then explain why plants from these two ecosystems will have different adaptations. in your answer, explain the survival challenges that plants face in these two environments.
