Does DNA replication occure immediately before asexual reproduction before sexual reproduction or before both?
Any form of biological reproduction, whether sexual or asexual, is going to involve the replication of DNA. You can't have new cells without new DNA.
Asexual reproduction increases genetic variation-the raw material on which natural selection operates?
Asexual reproduction decreases genetic variation which is the raw material on which natural selection operates. This is because asexual reproduction produces identical offspring to the parent.
Why do algae and fungi shift to the sexual mode of reproduction before the onset of unfavorable conditions?
due to unfavourable conditions they may not be able to go through asexual reproduction,so to providi resistance againsts these conditions they under go sexual reproduction.here there comes diversity and variationswhere genes become strong and can live,survive through these conditions
Where does replication of a genome take place?
genomic replication, or DNA replication, is performed by multiple enzymes that together are called a replicase. This replication takes place within the nucleus of a cell
What are two advantages of asexual reproduction?
1. It does not require another organism to mate with the reproducing one 2. This can possibly be initiated when the organism is mature than in a sexually reproducing animal which depends on finding a mate for reproduction, thereby reducing the span of the time before reproduction and making the increase in population quicker

What process must occur before asexual reproduction begins?
DNA replication
How can an organism produced by asexual reproduction be unique?
It cannot. Asexual reproduction is where a simple organism splits itself into exactly two halfs. Each half looks identical to the original organism before asexual reproduction.

Asexual reproduction decreases genetic variation which is the raw material on which natural selection operates. This is because asexual reproduction produces identical offspring to the parent.
Is it true that DNA replication can also be called mitosis?
DNA replication is technically not part of mitosis. Mitosis is simply the splitting of the nucleus. DNA replication however is part of the interphase, which is part of the cell cycle. The DNA replication is also known as the S phase in the interphase. In this part, the DNA is replicated creating two sets of all genetic information.
Is a zygote a premature egg?
A zygote is a fertilised egg cell. It is when it is only one cell so before asexual reproduction begins. After it reproduces it eventually becomes a foetus.

What is a sexual and asexual reproduction?
The term "asexual reproduction" means that new plants are created without the need for gametes. Self-pollination is not asexual reproduction -- the same plant merely provides both of the gametes used.The two main forms of asexual reproduction (apomixis) arevegetative (budding, rhizomes, aerial stems, or bulb division) andnon-vegetative, which includes parthenogenic or androgenetic seeds (agamospermy).
Why do starfish break so easily?
the can't have sex Who ever wrote that before this is stupid. Starfish can partake in both sexual and asexual reproduction. Sorry but I don't know the answer.
What is an example of an organism that can alternate between asexual and sexual reproduction?
Some plants (especially flowering plants), mammals (such as humans, lions, etc.), almost all reptiles, most insects and most fish (eg. Guppy) undergo sexual reproduction.
What characteristics do zygomycota have?
1. Multinucleate hyphae w/o septa (except in reproduction structures). 2. Fusion of hyphae leads directly to zygote formation in the zygosporangium. 3. Zygote meiosis occurs just before germination. 4. Most common type of reproduction is asexual.
