What is the primary effect of mutations in rabbit genetics?

The primary effect of mutations in rabbit genetics is that most are recessive and can be lethal. In genetics, a mutation represents a change in the DNA sequence, which can alter the function or characteristics of an organism. When these mutations occur, they are often recessive, meaning that two copies of the mutated gene are typically required for the effect to be expressed. If an organism carries just one copy of the mutated gene (heterozygous state), the dominant normal gene often masks the effect, keeping the individual from showing any symptoms or characteristics related to the mutation.

Additionally, some mutations can be lethal, particularly if they affect essential functions or development during critical growth stages. This is particularly notable in genetic disorders or changes that disrupt crucial gene functions. As a result, many mutations can lead to health issues or complications, especially if expressed homozygously.

While some mutations can lead to positive traits or adaptations, the notion that all mutations are beneficial is fundamentally inaccurate. Many mutations do not improve traits like fur quality or overall health; hence, the idea that most mutations enhance fur quality or are always dominant does not reflect the complexities of genetic variation and expression in rabbits.
