Answer:
Reproductive isolation refers to the inability of an organism or species to breed successfully with other organism or species.
It may arise from various factors such as:
- Geographical isolation such as river, mountain, etc
- Behavioral changes such as mating time or season, mating rituals, mating location etc.
- Physiological differences such as change in shape of sex organs which causes lack of fit between copulatory organs.
- Genetic differences.
Reproductive and geographical isolations between two populations (of same species) inhibit the flow of genes among them. Slowly, these isolations increase the variations in the gene pools of the two populations.
These genetic variations keep on increasing with time. In addition, as an adaptation to their surrounding or habitat the two populations would develop different behavioral and physiological changes
With time, these differences will increase up to such an extent that the two populations would not be able breed with each other. Hence, it would lead to the evolution of one or both the populations into new species.
in lakes or wetland such as marshes or swamps
Answer:
In a pedigree chart, the line which is horizontal shows the parents which mated and produced the children which are represented in the vertical lines below them.
A pedigree chart can be described as a diagram which illustrated the sequence of ancestors of an individual. Often, a pedigree chart is used to look for genetic traits or genetic disorders which might run in the family history. Pedigree charts are important for understanding the probabilities of the offsprings in which a genetic disorder might occur due to family history.
You end up with decondensed chromosomes and two identical cells. After the process has ended the cells enter interphase and repeat the replication process.
A. It is responsible for keeping the back and legs straight in line when you're related.
