Which type of cell division results in offspring that have different genetic information from the parent?
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.
What sperm is formed during meiosis?
In the male, meiosis takes place after puberty. Diploid cells within the testes undergo meiosis to produce haploid sperm cells with 23 chromosomes. A single diploid cell yields four haploid sperm cells through meiosis.
What is the result of reproduction?
Reproduction (or procreation or breeding) is the biological process by which new individual organisms – “offspring” – are produced from their “parent” or parents. Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction.
What do you call the type of reproduction wherein each fragment of an organism develops into a new organism?
Fragmentation
Fragmentation occurs when a parent organism breaks into fragments, or pieces, and each fragment develops into a new organism. Starfish, like the one in Figure below, reproduce this way.
Why are organisms of the same species likely to reproduce?
People’s DNA is likely to be more like their father or mother’s DNA than their cousin’s or grandparent’s DNA. Organisms of the same species have the highest level of DNA alignment and, therefore, share characteristics and behaviors that lead to successful reproduction.
What happens to a new organism after fertilization?
From fertilization, it is a new organism that is alive and will continue to grow and develop as long as nutrition is provided and its life is not ended through violence or illness. Artistic metal representation of DNA double-helix structure.
Which is the first cell in the development of an organism?
Recall that a zygote is a fertilized egg: the first cell of the development of an organism that reproduces sexually. Therefore, a prezygotic barrier is a mechanism that blocks reproduction from taking place; this includes barriers that prevent fertilization when organisms attempt reproduction.
When do sperm and egg form a new organism?
in a sexual reproduction, the joining of a sperm and egg. zygote. new diploid cell formed when a sperm fertilizes and egg; will divide by mitosis and develop into a new organism. diploid. when a cell has chromosomes in pairs.
