| Question | Answer |
|---|---|
| Offspring | Young organisms that look like their parents |
| What are the two types of reproduction? | Asexual and sexual |
| Asexual reproduction | A single individual is the parent. The parent passes copies of it’s gene to its offsprings so the offspring are genetically identical. Also reproduces quickly and can provide a long number of offspring in a short period of time. |
| Sexual reproduction | There are two parents each parent contributes, half of its genetic information to the offspring so the offspring are genetically different from both parents most multicellular organisms reproduce this way this way also takes more time and fewer offspring |
| Can organisms reproduce both ways | Yes, organisms that can use Both types of reproduction include fungi, many plant, some reptiles and fish and a few types of insects, depends on the environmental conditions on their other factors. |
| Genetic variation | Genetic variation only happens during sexual reproduction. It also increases the chance that some offspring will have new traits that will help them survive a changing environment. |
| Male bluegill create nests for female bluegill to leather eggs. The male bluegill fertilize the eggs with their sperm, male bluegill guard the egg until they hatch. Is this sexual? Or asexual? Or both? | Sexual reproduction |
| Male and female jellyfish release, sperm and eggs into the water. A fertilized egg developed into a larva that will grow into polyp. The polyp will release a portion of its body into the water that will grow into an adult jellyfish. | Both asexual and sexual reproduction |
| Corals can reproduce a variety of ways one way is by a process that can produce a new coral from a fragment. A portion of a coral may be broken off by a boat, a person or an animal the broken piece can grow into a new coral. asexual? sexual ? both? | Asexual |
| Reproduction | Organisms inherit genes, which are segments of DNA on chromosomes the genes inherited from the parent or parents determine the genetic traits of the offspring. Asexual.= one parent, sexually.= two parents |
| Budding | Asexual reproduction when a bud begins to grow on an adult body then it develops a mouth and tentacles and the bud breaks off from the adult and becomes its offspring |
| Prokaryotes are… | Unicellular and reproduce by type of cell division called binary fission |
| Binary fission | A process results into unicellular organisms that are genetically identical to the parent |
| The steps asexual reproduction | First, the parent cell duplicates its DNA (duplicates so the offspring can have the same DNA) then there is the separation of cells, then finally there are two genetically identical cells |
| Genetically identical offspring | Ensures that any favorable traits that the parent has are passed onto the offspring however, if the environment changes a population with low, genetic variation, is less likely to have individuals with traits that allow them to survive |
| Generation time | If certain types of bacteria reproduce every 20 min this is called generation time |
| Gametes | Sexual reproduction uses 2 parents. Each parent produces sex cells. Females eggs, males sperm. |
| Fertilization | When an egg (female) and sperm (male) join together |
| Zygote | A new genetically formed cell from reproduction. This has a complete set of new genetic material that is half of each parent |
| Environmental factors | This can alter reproduction. Things such as light, temperature, and food supply |
