Henriette van der Dirk van den abeele lovebirds to become associated study leader of her PDH study to sequence the genome of genus Agapornis.

The first species on the list was Agapornis roseicollis and in we collected blood samples of these birds. The genome of Agapornis roseicollis has been sequenced in Please feel free to read it here: Currently, we are busy developing the parentage verification test for all lovebird species.

This will allow breeders and buyers to verify the parents of a bird before it is sold. We also hope to develop a test to determine if a young is a split for a specific color mutation, dirk van den abeele lovebirds before it is sold.

This will, however, be in a later stage of the dirk van den abeele lovebirds and this will be the hardest part since it has never been done before and it will probably take a few years.

This will cost a lot of money. Therefore we need to get some extra money and we will soon start fund raising. The North-West University in Potchefstroom, South Africa has started a study to sequence the genome of the lovebird that will allow the identification of markers useful to verify parentage and to identify the mutations causing colour variations.

The DNA structure of humans, birds, animals, plants, viruses and bacteria are all the same. DNA is densely packaged into chromosomes and each species has a different number of chromosomes.

If we could pull the chromosome apart we will find a double helix structure that is the DNA. Imagine the DNA molecule as a spiral staircase.

Each step of the staircase is a base pair. Chromosome, DNA structure with two genes and the base sequence of Gene 2 The sequence in which the bases are arranged are fixed for a specific species.

However there are areas where the bases differ and this causes genetic diversity. This is called a mutation. A mutation can have either a positive or negative effect. A positive effect includes a colour variant where a negative effect can lead to an inherited disease or abnormality.

This mutation can simply be a substitution of one nucleotide for another e. The easiest illustration of the difference between a gene and a marker is to imagine the DNA as a long stretch of road.

On your travels you will pass through areas where there are towns and areas where there dirk van den abeele lovebirds open fields.

The towns or genes have a specific sequence — there is the supermarket, then the hairdresser, then the liquor store etc. The open areas or junk DNA have no specific function. However there may be a big rock or hill 1. This acts as a marker — it is a fixed object that always look the same and always at the same spot.

A gene is a segment of DNA with a specific function like the town and it needs to be in a specific sequence to be functional. Its function is to produce proteins that are again used in different physiological processes. For example the genes involved in feather colour pigmentation has the function of sending a message to produce pigment for the feathers.

Markers are mostly found in the junk DNA areas. We make use of Dirk van den abeele lovebirds as genetic markers because these changes polymorphisms of one single base nucleotide is inherited from parent to offspring allowing us to identify which individual has sired which offspring. For a parentage verification test the parents and the offspring need to be tested at the panel of SNPs and the data of the three animals are compared.

If the male is the sire the chick had to inherit one copy dirk van den abeele lovebirds the male and if the female is the dam it had to inherit dirk van den abeele lovebirds copy from her.
