Correct option is A
Correct Answer: (1) Eucalyptus phylacis (Australian Meeup Mallee)
Explanation:
Eucalyptus phylacis (Australian Meeup Mallee) is indeed a rare and endangered plant species, and it has been documented to have exceptionally low genetic variability, as reported by multi-locus molecular studies. Low genetic variability in this species makes it more vulnerable to environmental changes, diseases, and other ecological pressures. The small and isolated populations of Eucalyptus phylacis result in limited genetic diversity, which hinders its ability to adapt to new challenges.
Information Booster:
Eucalyptus phylacis (Australian Meeup Mallee): This species is critically endangered, primarily due to habitat loss, and has one of the lowest levels of genetic variability among Australian eucalypts. Molecular studies have shown that due to its small population size and fragmented distribution, this species faces challenges related to genetic bottlenecks, which limits its evolutionary potential and survival prospects.
Additional Information:
Option (2) - Impatiens parviflora: While this species is rare in some areas, it is not known to have exceptionally low genetic variability. It is more common in temperate regions and does not face the same genetic risks as Eucalyptus phylacis.
Option (3) - Pavo cristatus: The Indian peacock is not endangered, and it is not associated with low genetic variability. In fact, it is widespread in India and has a stable population.
Option (4) - Hydrobates castro (Hawaiian Band-rumped Storm Petrel): Although this species has been documented to have low genetic variability, Eucalyptus phylacis is more widely recognized for its exceptionally low genetic diversity based on multi-locus molecular research.
