Genetics:
The interaction of an organism's genes with the environment causes resemblances and differences between related organisms.
Reproduction
Sexual Reproduction
Disadvantages
In the Pittsburgh Post-Gazette article "Zoos call on wild elephants," the author states that it's extremely difficult to get animals to mate when they're not in the wild.They've been successful with very few elephants, but even when they do succeed, there isn't enough differences in the DNA because all the baby elephants have the same father.
Advantages
In the Los Angeles Times article "Scientists look at woolly mammoth genes to see why they died out" the author informs "that an advantage of sexual reproduction is genetic variety." Without diversity in genetics, animals wouldn't be able to adapt to environmental changes as quickly and/or as easily.
Asexual Reproduction
Disadvantages
In the Washington Post article "It's a long story: How we got the best and brightest fruits and veggies" the author describes "Each banana plant is cut from the roots of a single mother plant. It is then replanted and turns into a large banana plant" This doesn't help because the clones have the exact same DNA, which is unable to adapt to protect itself from pest and diseases.
Advantages
In the Wahington Post article " All-girl Salamanders" the author describes "that mothers make copies of themselves rather than mating with boy salamanders." This saves time and energy not having to find a mate.

Heredity: The transmission of genetic characteristics from parents to offspring... (This is not a physical thing)
Genotype: The science of heredity, dealing with resemblances and differences of related organisms resulting from the interaction of their genes and the environment…In other words: The interaction of an organism’s genes with the environment causes resemblances and differences between related organisms.(This is not a physical thing.)
Phenotype: the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.

Genome
Chromosomes
DNA/Genes
-
The basic physical unit of heredity, a linear sequence of nucleotides along a segment of DNA that provides the coded instructions for synthesis of RNA, which, when translated into protein leads to the expression of heredity character
Any of several threadlike bodies, that carries the gene: Humans have 23 pairs, designated 1 to 22 in order of decreasing size and X and Y for the female and male sex chromosomes respectively

Artificial Selection
Natural Selection
Another example for natural selection is a deer mice its fur changed from a dark brown to a light brown in order to hide from their prey in the sand.
-
Red bugs vs Green Bugs, this is an example of natural selection, red bugs are more preferred by birds instead of the green ones. So the green bugs can reproduced causing the red bugs to reduce in quantity.
-
Breeders Breeding a massive cow and a good producing cow, this creates the desirable cow that the breeder(s) wants.
-
The Brassicas (cabbage, broccoli, cauliflower, brussel sprouts, collard greens, and kale) are another example of artifical selection.
