heavy emigration, disease, famine, and war.
<span>Homologous chromosomes exchange DNA during meiosis in a process called crossing-over. Crossing-over sometimes involves an unequal swapping of DNA. Basically one chromosome in the pair gets extra DNA.</span>
Answer:
See the answer below
Explanation:
First, the image tells that chromosomes are made up of genes or that genes are located on chromosomes. It further showed that genes are translated as proteins in the cell and this protein respectively control the expression of traits.
Secondly, it also showed that during sexual reproduction, the offspring produced usually have the same proteins as the parent and therefore have exactly the same traits as the parent. Only one parent is needed for asexual reproduction.
<u>However, two parents are needed for sexual reproduction where each parent donate chromosomes containing gene to the genome of their offpsring. The mixture of genes ensures that the offspring look different from the parent.</u>
<em>The image further showed that asexual reproduction does not lead to any variation while sexual reproduction leads to variation of the offpsring from their parents.</em>
Answer AND Explanation:
The islands had different environments, and the organisms had adaptations that enabled the organism to live in those environments. The island had been inhabited by its own kind of species found nowhere else in the world. Darwin also noticed that considerable variation exists between members of the same species. Offspring vary from their parents and between themselves.
The answer is C: Inheritance
