An Analysis Of Gene-Enzyme Variability In Natural Populations Of Drosophila Melanogaster And D. Simulans, Stephen J. O'Brien, Ross J. Macintyre

Biology Faculty Articles

Nine populations of D. melanogaster and two populations of D. simulans were analyzed for polymorphism in 10 gene-enzyme systems by the technique of gel electrophoresis. In the eight natural populations of D. melanogaster, an average of 54% of the enzymes were polymorphic, and the average heterozygosity was 22.7%. An experimental population of D. melanogaster, which has been maintained in a laboratory cage for 20 years, showed levels of polymorphism equivalent to those of natural populations. The D. simulans populations had much less variability. The possible factors involved in maintaining these polymorphisms are discussed.

Ultrasonic Testing : An Aid To Better Breeding, B M. Goss

Journal of the Department of Agriculture, Western Australia, Series 4

THE ultrasonic tester was originally developed as a metal flaw-detector for industrial purposes, and its usefulness for making carcass measurements on the live pig was first demonstrated about 10 years ago.

Breeding Better Pigs, B M. Goss

Journal of the Department of Agriculture, Western Australia, Series 4

IN the past, pig breeders have tended to select animals on physical characteristics, many of which have little or no relevance to economy of production.

Selection techniques now available open up the possibility of improved pig production efficiency.

The Importance Of Milk Production In Beef Cattle, W J O Wilkie

Journal of the Department of Agriculture, Western Australia, Series 4

IN recent years there has been a great deal of comment on the need for "dairy blood" in the State's beef industry.

There seems to have been some confused thinking on this matter. There is no doubt at all that a beef dam should be able to produce enough milk to do its calf well.

But there is nothing to gain and a great deal to lose if too much emphasis is placed on milking qualities without reference to beef qualities.

The Role Of Fleece Measurement In Selecting Merino Sheep, H G. Neil, R. J. Lightfoot

Journal of the Department of Agriculture, Western Australia, Series 4

MANY things determine how much wool a sheep can grow.

These include the amount and quality of pasture available or how the sheep are fed, the stocking rate, the general health and thrift of the sheep and other management considerations such as cropping and the time of lambing.

First Three Year Average Report For The West Australian Random Sample Laying Test Covering The 4th, 5th And 6th Tests, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

FIRST THREE-YEAR-AVERAGE REPORT FOR THE WEST AUSTRALIAN RANDOM SAMPLE LAYING TEST COVERING THE 4th, 5th AND 6th TESTS

Despite every effort made to provide all entries in individual tests with a uniform environment it is still possible for a particular entry's performance not to be a true indication of its inherent ability.

Random Sample Test results should therefore be viewed on a long term, annual, consecutive basis. If the yearly results for a given hatchery are grouped together and averaged over a period of several years irregularities in performance due to factors other than genetic worth are minimised and a …
