Recessive
Recessive:
A recessive gene has some effects on the phenotype only in its homozygous (2c / 2 copies) form, the heterozygous (1c / 1 copy) form is carrying the gene but is not distinguishable from a normal phenotype. Both parents must carry the gene to produce a visual animal.
An exemple (Blizzard) of a recessive gene inheritance probabilities:
​
Blizzard x Normal
=
100% het Blizzard
​
-------------------------------------------------------
het Blizzard x Normal
=
50% het Blizzard, 50% Normal
(as we cannot differenciate the het from the normal, all of them will be poss het Blizzard)
​
-------------------------------------------------------
​​
het Blizzard x het Blizzard
=
25% Blizzard, 50% het Blizzard, 25% Normal
(as we cannot differenciate the het from the normal, all of them will be poss het Blizzard)
​
-------------------------------------------------------
​
Blizzard x het Blizzard
=
50% Blizzard, 50% het Blizzard
​
-------------------------------------------------------
​
Blizzard x Blizzard
=
100% Blizzard
