Aoa/hello/ friends! kia haal hai? umeed krta hon sab kheriyat se hon ge....\r
\r
jo bhae pareshan hein egg fertile nae hoty ya female parrot/budgie \r
\r
egg dy dy tu vo khali hoty hein anday bache nae krte...\r
\r
\r
mera experience hai mei 110% yaqeen k sath keh sakta hon kyke \r
\r
mere pass 30 pair hein or mere pass 150 healthy bachon ka flok \r
\r
nikla hai\r
\r
kuch meine sale kr diye kuch meine rakhe hein agy breeding k liye inshaallah uska result b apko next year dikhaon ga\r
\r
try this trick n enjoy increase birds stay happy\r

On the right is a punnett square, a tool to help work out the possible results of a mating. Lets have a quick look at one so we can use them when we cover the types of inheritance in a minute.\r
\r
\r
Let us use the example of a mating between a budgie with the geneotype AA and one with Aa (we wont worry about what they represent at the moment). Each chick from this mating will receive one gene from each parent. So we enter one parents genes into the top boxes, and the others into the boxes on the left hand side. Then copy the top ones down and the left hand ones across to the right, which gives four genotypes.\r
\r
So in this case mating a bird with AA with a bird with Aa produces two possible genotypes: AA and Aa. Later we will look at more complicated examples giving several different genotypes from a single mating.\r
\r
Once we cover the part of budgie genetics where we discover which genes produce which colours, you can use a punnett square to work out the results of matings.\r

\r
Types of Inheritance\r
\r
Now that we know a little bit about genes, lets look at how we can use genetic symbols and punnett squares to work out what genes your budgie has. Remembering that your budgie has two copies of each gene (one from each parent) I thought we would start with the example from the Basic Genetics page; the budgie that has received one gene for green body color and one gene for blue. What colour will it be?.And the answer is..GREEN! This is because blue is a recessive gene. but what does that ually mean?!!\r
\r
Dominant and Recessive Genes\r
\r
Mutated genes are categorised by how they inter with the original (wild type) gene. If a budgie carries both the wild type (eg. green) and the mutated (eg. blue) gene but the bird is green then the mutated blue gene is said to be recessive to the wild type. If the budgie looks like the mutated gene then it is said to be dominant to the wild type.\r
\r
The link below will take you to more information on this and on some dominant and recessive varieties. Grasping this concept will be the foundation of your understanding budgie genetics.\r

\r
Incomplete Dominance\r
\r
In the usual dominant vs recessive gene interions you have three possible genotypes but only two possible phenotypes. As an example:\r
\r
AA - homozygous wild type, appears wild type\r
Aa - heterozygous, also appears wild type\r
aa - homozygous mutated gene, appears like the mutation\r
\r
There is another type of dominance though, incomplete dominance. With this type of inheritance you get three genotypes with three phenotypes:\r
\r
AA - homozygous wild type, appears wild type\r
Aa - heterozygous, appears in-between the two homozygous types\r
aa - homozygous mutated gene, appears like the mutation\r
\r
There are a few examples of this in budgie genetics. If you want to know which varieties work like this, then click here and read on.\r
\r
Multiple Alleles\r
\r
So far we have looked at situations where a gene has mutated once giving two possible alleles of that gene; the wild type and the altered version. But what happens if the same gene mutates more than once, creating three or more alleles?\r
\r
This is exly what has happened with a couple of budgie varieties. There is a gene which produces full strength body color and markings represented by the symbol Dil. It mutated to create a budgie with greatly diluted body color and markings, the variety called dilute - dil. The gene mutated another time and produced a bird with the body color and markings diluted by about 50%, the greywing - dilgw. It mutated yet another .
