Sentence examples for long generation interval from inspiring English sources

Trees have long generation interval and breeding is therefore a slow process.

This leads to a moderate to long generation interval, substantial costs and complex logistics for phenotypic recording [ 1].

In Atlantic salmon, such populations are relatively rare, and the production of divergent or inbred lines is a long term undertaking due to the long generation interval.

We thus focused on the oil palm species, for which current conventional breeding is characterized by a long generation interval, due to progeny-tests, and by small populations.

Other factors include the long generation interval of livestock, costs involved, lack of inbred lines, the difficulty of producing 'knock-out's [ 45] as well as possible conservation of LD within small chromosomal regions.

The long generation interval (13 years) for saltwater crocodiles [ 22], coupled with the relative infancy of the industry, means that no deep pedigrees are available for making DNA resources for mapping.

For these species, it is difficult or impossible to generate inbred lines due to long generation intervals and high heterozygosity [ 4], although experimental hybrids have been commercially used in practical breeding programs.

However, the long generation intervals and the difficulty of accurately evaluating traits in early stages have hampered progress through breeding [ 3].

The reason for these high genetic relationships are the long generation intervals in cattle and the low effective population size of 40-50 (personal unpublished studies, estimated from pedigree).

However, traditional breeding has remained a slow process because of long generation intervals and because most traits cannot be correctly evaluated at an early developmental stage.

Given the long generation intervals in cattle the number of generations of intense artificial selection is still small which could result in weak selection signals for alleles with small effects.
