Which of the following represents hybrid inviability? A) A hybrid offspring is born healthy and fertile. B) A hybrid grows to adulthood but is unhealthy. C) A mule is born but cannot reproduce. D) A zygote forms but does not develop.
Understand the Problem
The question is asking which option correctly defines hybrid inviability, a concept from the study of reproductive barriers in biology. This involves understanding the outcomes of hybridization between different species.
Answer
D) A zygote forms but does not develop.
The correct option is D) A zygote forms but does not develop.
Answer for screen readers
The correct option is D) A zygote forms but does not develop.
More Information
Hybrid inviability refers to a postzygotic barrier where the hybrid zygote does not develop properly and often dies at an early stage. This occurs early in hybrid development, unlike hybrid sterility which affects adult hybrids like mules.
Tips
A common mistake is confusing hybrid inviability with hybrid sterility. Hybrid inviability occurs when the hybrid organism fails to develop fully or reach reproductive age, whereas hybrid sterility occurs when the hybrid is reproductively mature but unable to reproduce.
