No. Males are quite a bit larger. Females weigh from 350 -600 pounds. Males can weigh nearly 1200 pounds.
600% of 1200 = 600% * 1200 = 6 * 1200 = 7200
1200-600=600
1200/2=600
But your question is nicely answered in Wikipedia under: http://en.wikipedia.org/wiki/Effective_population_size 1/Ne = [1/600 + 1/400 (when there are 200 males and 200 females)] / 2 = [5/1200] / 2 = 0.00208... so that Ne = 480 for these 1000 ainmals. If the sex-ratio differs, you just follow the other example and formula given under the above mentioned link. Cheers, Ulrike
12 metres is 1200cm. 1200:54 is 600:27 = 200:9
1200
Big males can weigh over 600 pounds, but average 450-500. Females around 300 pounds. They can be over ten feet long for males, including the tail, and eight feet for females.

Depends on the subspecies. Males of the Siberian and Bengal subspecies can be 500-600 pounds, while the Sumatran males rarely reach 300. Females are around 3/4 as large as males.
adult males range between 550-1,300lbs adult females range between 600-1,160lbs
The males range around 600 to 900 pounds and females are 400 to 650 pounds.
