Hello everyone.
00:01
In today's question, we are examining five evolutionary and genetic concepts alongside examples to identify any inconsistencies between the terms and their provided examples.
00:13
The concepts are population bottleneck, inbreeding depression, inbreeding, gene flow, and founder effect.
00:40
Population bottleneck.
00:41
A population bottleneck occurs when a significant portion of a population is suddenly eliminated, leading to a drastic reduction in genetic diversity.
00:54
For example, 75 % of frogs killed during a cold snap aligns with the definition as it describes a sudden reduction in population size.
01:21
Inbreeding depression.
01:23
Inbreeding depression refers to a decline in population fitness and health due to breeding between closely related individuals, which increases the probability of offspring inheriting harmful, excessive traits.
01:41
Now, the example, you know, a decline in cougar population fitness due to mating with blood relatives is consistent with inbreeding depression.
02:00
Inbreeding.
02:01
Inbreeding occurs when individuals who are genetically closely related reproduce, leading to an increased chance of offspring inheriting identical alleles from both parents.
02:14
Now, in the example, a mouse inheriting both copies of an allele from its grandmother accurately represents inbreeding...
