Answer:
X-linked is a trait where a gene is located on the X chromosome. Humans and other mammals have two sex chromosomes, the X and the Y. In an X-linked or sex-linked disease, it is usually males that are affected because they have a single copy of the X chromosome that carries the mutation.
Explanation:
Answer:
Mitosis produces all animal and plant cells, tissues, and organs excepts for the gametes ( the eggs and sperm). Since mitosis produces genetic clones of the parent cell when it divides, all animal and plant cells that grow from a fertilized egg (zygote) are more or less genetically identical.
Explanation:
Science
<span>Natural selection is when
species learn to adapt to their environment. They could (1) differential
reproduction, that is, not all organisms are able to reproduce to their fullest
capacity because nature cannot simply sustain it and (2) acquire genes, that is
heredity. Certain characteristics of organisms tend to survive if it continues
to strive. If it survives, this trait is passed down to the next generations
forgetting the other traits but only the one who could survive the environment.
Therefore it is true that <span>natural selection is when
‘organisms inherit advantageous traits, and tend to reproduce more successfully
than other organisms’</span></span>
