Be sure your essay is at least one paragraph long, but you are welcome to write more. Be specific in your response by referencing chromosomes and cell phases to support your explanation. You may look back at your summary questions to help you complete this essay. Please provide your answer in the space below. hp ΣAbout sexual reproduction: Involves one parent where a new individual develops being an exact copy of the parent also known as clone and no gamete or reproductive organ is involved O Only the mother contributes with the oocyte or egg where a new individual is formed with an exact copy of the mother's genes O Involves two parents, where each parent contributes with special germ cells or gametes that once united in fertilization, a new individual develops receiving genetic material from both parents and the product of gene recombination O Involves the father only which contributes with special germ cells or spermatozoa that once fertilized, a new individual develops receiving genetic material from the father and the product of gene recombination Next » « Previous
- | The Role of Meiosis Key Idea: There are two types of cell division in eukaryotes, mitosis and meiosis, but only meiosis produces cells that are genetically different to the parent cell. New cells are formed when existing cells divide. There are two forms of cell division in eukaryotes, mitosis and meiosis. Mitosis produces two identical daughter cells from a parent cell. Meiosis is a special type of cell division, and produces sex cells (gametes or spores) for sexual reproduction. In sexual reproduction, sex cells from two parents combine to form an individual that is genetically different to its parents. The sex cells in humans, called eggs and sperm, are produced by meiosis. Events occurring during meiosis creates gametes with unique combinations of gene variants and so creates genetic variability. Sexual reproduction rearranges and reshuffles the genetic material into new combinations. This is why family members may look similar, but they'll never be identical (except for…Hi can I get help with this question please? I am stuck!! Topic is sexual reproduction and it’s physiology. Scenario: Hefty Harry is tall, muscular, produces sperm, and he has a thick beard, high concentrations of circulating testosterone, and a penis. In other words, he very much looks like a man. However, when he got his genome sequenced, he and everyone else were extremely surprised to learn that he has two X chromosomes. He comes to ask you how this could be possible. You tell Hefty Harry that it’s possible...(see image)Based on Standard NGSS MS-LS3-2: Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation. In reference to the attached image, can you create a model that shows how it is possible that the twins ended up with such different traits yet have the same parents? Keeping in mind that the twins are a set of fraternal twins.
- A diploid organism has chromosomes. Use colours or symbols to show which chromosomes are which throughout each stage. Draw and label the chromosomes, sister chromatids, centromeres, spindle fibres, tetrad, crossing over and nucleus where appropriate.

She already had 6 children, and all 14 of her children were conceived via in vitro fertilization (IVF). IVF involves removing eggs from the ovary, fertilizing them with sperm in a petri dish, and transferring the resulting embryos back into a uterus to develop. It is common for two or three embryos to be transferred into the uterus of a woman undergoing IVF to increase the chances of at least one of them surviving. When Ms. Suleman became pregnant with her octuplets, Dr. Kamrava had transferred 12 embryos. His license was revoked in 2011.Multiple eggs are required for IVF to produce functional embryos because some eggs are not fertilized or do not develop normally after fertilization.
