Is cloning by sexual reproduction?
No. Sexual reproduction involves a fusion of the nuclear contents of one gamete (say, a sperm), with the nuclear contents of another gamete (say, an egg). The resulting cell has two alleles, or versions of a gene, for every gene in the (nuclear) genome. This cell (a zygote) thus has a full diploid nuclear genome, having derived half of its genes from its father and half from its mother. During cloning (at least during somatic cell nuclear transfer, which is one type of cloning method), a full diploid nucleus from a somatic cell is transferred to an egg cell that has had its nucleus entirely removed. In this way, all of the nuclear genes come from one individual- whoever the nucleus of the somatic cell's owner was. So, to reword, during sexual reproduction, half the genome comes from the mom and half from the dad, but during cloning, the whole genome comes from one individual, but gets put into an egg that has been emptied (or, enucleated).
During sexual reproduction the new offspring gets some of its traits from its mother and some from its father?
During sexual reproduction, the offspring inherits half of its genetic material from the mother through the egg and half from the father through the sperm. This combination of genetic material determines the traits and characteristics of the offspring.

Cellular Reproduction
Why do organisms favor sexual reproduction?
1. The Random Distribution of Chromosomes in Metaphase I Homologous chromosomes arrange themselves randomly at the equator of the spindle randomly in metaphase I.The consequent random assortment of chromosomes makes new genetic combinations. 2. Crossing Over of Homogolous Chromosomes 3. Mutation
Why we humans look so alike but yet different?
in sexual reproduction,an offspring gets 23 pairs of chromosomes from both parent- as in meiosis cell division.therefore this lead to a differences in the genetic material through which humans were made.NOTE-DURING MEIOSIS CELL DIVISION THE CELL MAKES SURE THE PAIRS OF CHROMOSOMES FROM BOTH PARENT ARE DIFFERENT,THAT LEADS TO VARIATION WITHIN OFFSPRINGS AND PARENTS.CERTAINLY YOU DO NOT LOOK EXACTLY LIKE EITHER PARENT.FACIAL APPERANCE COULD BE THE SAME BUT NOT BEHAVIOURAL PATTERN.IT IS SHARED.
What is the same in reproduction between fish and humans?
Fish and humans both use sexual reproduction. This means that one sperm cell (from the father) and one egg cell (from the mother) combine to form an embryo. Now the embryo gets half of its genetic material from each parent. Sexual reproduction doesn't neccessarily mean an organism "has sex" as we know it, however. Fish release sperm and egg cells into the water instead of physically having sexual intercourse. When the egg is fertilized outside of the mother's body, it's called external fertilization.
Contrast the overall Role of mitosis and meiosis in plant and animal?
Mitosis in both plant and animal cells is responsible for growth, repair, and asexual reproduction, producing identical daughter cells. Meiosis, however, forms haploid gametes used in sexual reproduction, leading to genetic diversity in offspring. Both processes are essential for the life cycle of both plants and animals, but meiosis plays a unique role in sexual reproduction.
Is cloning by sexual reproduction?
No. Sexual reproduction involves a fusion of the nuclear contents of one gamete (say, a sperm), with the nuclear contents of another gamete (say, an egg).

Which type of reproduction results in the greatest amount of genetic variation?
That would be sexual reproduction. Sexual reproduction allows for independent assortment and crossing over to occur. This is fancy language for the genetic material gets mixed up a lot. Since the genetic material gets mixed up, variation will result.
Reproduction from one type of cell?
im not quite sure what you mean here but the there are a few types of asexual reproduction that cell preform two of these i know about are binary fission where the cell splits in to which is where the mother cell get slip including the nucleus and genetic material gets copied and the other is budding where a mother cell grows a cell on the side of it and the nucleus gets copied and moved into the growing cell or budding cel then daughter cell splits off and continues to grow
What is plant reproduction?
Plants reproduce by spreading seeds. These seeds are fertilized by animals, such as bees, also called pollinators. The pollinators (the animals) pollinate the plant. The male cell goes into the ovary and fertilizes the seed. When the time is right, the plant disperses the seed and it gets planted.
How bacteria reproduce?
Bacteria reproduce using two basic methods: Asexual reproduction and Sexual reproduction. Bacteria can reproduce both sexually and asexually. Sexual reproduction involves the joining of two parents and the exchanging of genetic materials. Asexual reproduction involves only one individual or parent. The offspring generated by asexual reproduction are exact duplicates of the parents.Binary Fission is the process by which a bacteria splits into two cells. Each cell gets an exact copy of the parent cell's genetic material. I hope this answered your question! <3
During sexual reproduction the new offspring gets some of its traits from its mother and some from its father?
During sexual reproduction, the offspring inherits half of its genetic material from the mother through the egg and half from the father through the sperm. This combination of genetic material determines the traits and characteristics of the offspring.
Why does sexual reproduction result in greater dicersity among offspring than does asexual reproduction?
Because sexual reproduction involves two seperate creatures, each with it's own chromozones to pass on to the child. In asexual reproduction, there is only one creature, so only one set of chromozones can be passed on. I.E: In humans, both the mother and the father pass on 23 chromozones, so the baby gets 46, half from the mum and half from the dad, so there is more variation. In a strawberry plant, the mother plant is the only entity that can pass chromozones onto the child, so the child will be genetically identical to the parent plant.
Which structure controls cell reproduction?
The part of a plant and/or animal cell that is pesponsible for reproduction is the centrioles.
What is responsible for reproduction?
reproduction are of 2 types sexual reproduction which involves gametes male gametes:-- sperms female gametes:-- ovum these 2 gametes need to be fused together to form an embryo then through mitosis it will divide millions of time to make a baby in plants male gametes:-- pollen grain female gametes:-- ovary in these when pollen gets in another flower due to pollination it forms an pollen tube through the style and fuses with the ovary and forms seeds!! in short the gametes are responsible for reproduction in sexual reproduction
