Transitions between biomes do not have to be sharp and sudden, which means that different biomes can share characteristics is a true statement.
The transition between two biomes is called an ecotone. The ecotone may have the characteristic of the two biomes in which it borders. It may have plant species from both biomes.
In addition to dividing ecosystems into aquatic and terrestrial, we can also speak of transitional ecosystems (or transitional biomes), which, as the name implies, are in transit between the first two, or rather, represent the passage from one to the other.

where does each strand of DNA from the parent molecule end up?
DNA replicates itself, so no, unlike what it may seem, parent organisms do not loose their DNA. Before the fecundation process, a cool process similar to miosis happens, it is called meiosis. During meiosis the parent chromosome will duplicate it self and break down each of its 46 chromosomes into 4 different new formed cells, which will become the sperm and egg cells. Each of these egg or sperm cells will be different from eachother, which is how you get siblings that don't look alike, however they will contain a copy of the parent's genetic information.
In conclusion;
In the creation of offspring, the copy of the parent's DNA breaks apart into 4 different pieces which will form sperm or egg cells.

Due to recessive certain hair color or other traits may come from parents, but other traits may not be exhibited. If two brunette parents have a blond child, they had to have instructions for making blond hair hidden in their DNA.
What are the factors responsible for brown hair?A person may have a gene for brown hair and a gene for blond hair. He would give one of those traits to his child. Each of two parent transfer two alleles for hair color. Blonde hair is a recessive gene and brown hair is a dominant gene.
Even though the gene passed down from parents to child determine hair color, variations in alleles can result in different hair color than both parents. In Human DNA has millions of on and off switches and networks that control how genes function. Genes responsible for hair color come from both parents.
