What are the 2 reproductive strategies?

These two main strategies are known as K-selection (few offspring) and r-selection (many offspring).

What are the 4 stages of the cell cycle?

In eukaryotes, the cell cycle consists of four discrete phases: G1, S, G2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases — G1 and G2, the so-called gap phases — are less dramatic but equally important.

What are the ways to reproduce?

There are two forms of reproduction: asexual and sexual. In asexual reproduction, an organism can reproduce without the involvement of another organism. Asexual reproduction is not limited to single-celled organisms. The cloning of an organism is a form of asexual reproduction.

What is inherited from the mother only?

Our mitochondrial DNA accounts for a small portion of our total DNA. It contains just 37 of the 20,000 to 25,000 protein-coding genes in our body. But it is notably distinct from DNA in the nucleus. Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.

What is the difference between reproduction of yeast and hydra though both organisms reproduce through budding?

Yeast is a unicellular organism while hydra is a multi-cellular organism In the yeast, the bud originates from a small protuberance on the parent body, while in hydra the bud arises due to the repeated mitotic division. The yeast gets their daughter nuclei and it may or not separate out from the parent body,…

What is the similarity between hydra and yeast?

“What is the similarity between Hydra and Yeast ?” Both Hydra and Yeast exhibit budding as the method of reproduction.

What plants have genders?

Ginkgo, kiwi, cannabis, and willow all have individuals that make only pollen or only seeds. Botanically, they are known as dioecious plants, and their strategy ensures genetic outcrossing. Interestingly, many street trees are dioecious, and, to avoid the mess of flowers and fruits, only male trees were often planted.

What requires one parent creating a clone of themselves no diversity large amounts of offspring?

Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent. A single individual can produce offspring asexually and large numbers of offspring can be produced quickly.

What type of reproduction requires male and female?

Reproduction can happen in two main ways: asexual reproduction, which requires only one parent, and sexual reproduction, which needs gametes, or sex cells, from a male and a female made by the process of meiosis.

Which of the following requires both parents of reproduction?

Sexual reproduction requires two parents. Each parent contributes a gamete – a sex cell that has half of the normal DNA of a regular body cell. In males, the gametes are sperm and in females, the gametes are eggs.

Which process produces offspring from two parents?

Sexual reproduction involves two parents and produces offspring that are genetically unique. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. Meiosis is the type of cell division that produces gametes.

Which species can produce offspring that are genetically different from their parents *?

Asexual reproduction involves one parent and produces offspring that are genetically identical to each other and to the parent. Sexual reproduction involves two parents and produces offspring that are genetically unique.

Why are we not identical to our parents?

Remember: everyone has two copies of every gene. Because we receive only half of our mother’s genes (one copy of each gene) and half of our father’s genes, we are not identical to either of our parents. With each pregnancy, the chromosomes from our mother and father combine in different ways.

Why do i look nothing like my parents?

Even though we get all our DNA from our parents, each of us has a unique combination of genes. Sometimes that means we don’t look like them at all. There are tons of genes that shape our appearance.

Why do children never look identical to their parents?

Children inherit pairs of genes from their parents. A child gets one set of genes from the father and one set from the mother. These genes can match up in many ways to make different combinations. This is why many family members look a lot alike and others don’t look like each other at all.

Why do offspring not look exactly like their parents?

Children inherit pairs of genes from their parents. A child gets one set of genes from the father and one set from the mother. These genes can match up in many ways to make different combinations. This is why many family members look a lot alike and others don’t look like each other at all.

Why do some babies only look like one parent?

Looking more like one parent or the other is dependent on the gene versions each parent has. And which ones happen to get passed down. We have two copies of each of our chromosomes and so have two copies of each of our genes.

Why don t moths have mouths?

Evolution didn’t prevent the moth having a mouth. It allowed the mutation, that involved not having a mouth, to persist, presumably (since it eventually prevailed) because it carried some other benefit, we cannot see without studying it.

Why has my anemone split in two?

The anemone splits when it feels it is in danger. ie: bad water conditions or more likely not enough food. It splits when signs are bad as a defense because twos smaller ones have a better chance of surviving than one bigger one.

Will 2 clownfish always pair?

Having two clownfish is always better than one. It keeps the fish happy, and you get to see more baby clownfish after they pair up and lay eggs. But before you start counting how many clownfish fry they will have, you need to know how to pair clownfish.

Does sea anemone has two parents?

When offspring is produced by a single parent with or without the involvement of gamete formation, it is called asexual reproduction. Dolphin:- Sexual reproduction, involve two parents. Sea anemone:- Asexually, through budding. Housefly:- Sexually, involve two parents.

Are earthworms born alive?

Worms do not give birth since babies come from eggs and are not live born. I suppose you can consider forming and depositing the egg-filled cocoon “giving birth.” The process of forming a cocoon full of worm embryos starts when the worms separate after mating.
