Hello everyone. And in today's video we have the following problem which of the following examples demonstrates parthenogenesis reproduction. And I want you to recall from previous videos what parthenogenesis reproduction means? Well it is a type of reproduction that occurs using a single gamut. So for example if we have females these females are going to be able to reproduce or create offsprings without the presence of a male. So it is usually done when males cannot be found in just the while or the environment. So females will record to this. So let's go over our answer choices now that we know this so we can use this information problem beginning by answer choice. A. The but from a praying his cell. Well this does that really explain parthenogenesis reproduction? What this is actually explaining is budding which is another type of reproduction as described in the answer choice. So we're going to cancel this out and move on to answer choice B bacteria dividing into two. This is what we call binary fusion and it is a type of division or cell division where bacteria able to reproduce or just divide into two cells with equal DNA. And this is not going to be an example of political genesis reproduction as it's not describing what the process really is. When we know we have answer choice D flowers pollinated by these. Well if a flower or just a plant is able to spread their pollen into other plants. This is going to be sexual reproduction because we have multiple gametes involved. So we're going to actually cancel this out as well as not being the answer. And this all leaves us with answer choice C all female lizards which developed offspring. Well, in this case the all female is going to be the single gamete that we're talking about here, and they're going to be able to develop offspring without depending on the male. So this is actually perfectly explaining the process of parthenogenesis reproduction, and we're going to highlight it as being the answer. So I really hope this video helped you and I really hope to see you on the next one.
