Sex-linked trait
As aforementioned, the G is dominant to g.
Parental Genotype: X^G Y (Male) X^g X^g (Female)
Pedigree Analysis
The ratio:
50% Heterozygous Female 2012
50% Male 2013
Description
Here are 2 chinese dragons, of the same species, however, some features appear to be different. The male dragon looks like the shape of the year 2012, and the female one looks like the shape of the year 2013. How can they reproduce offsprings?
Genetic Diagrams may help answer this question.
Conclusion
From two imaginary species, we can set up different genetic diagrams by using our knowledge of monohybrid inheritance.
2 single-allele traits
Blood System is the dragons
The 2012 shape gene is dominant to that of the 2013 one.
Let G = 2012 and g = 2013.
Parents genotype: Gg (male) gg (female)
It is known that the mother is of blood group A and the father is of blood group B.
Genotype: Mother I^A I^O Father I^O I^O
50% Blood Group A
50% Blood Group O
The ratio of the offsprings are as the following:
50% Heterozygous 2012
50% Homozygous 2013
Co-dominant trait
Let G = 2012 and g = 2013
Parents genotype: C^GC^g (male) C^gC^g (female)
Interestingly, the co-dominance effect of the mating of 2012 and 2013 will produce a 2014 shape dragon.
The ratio is of following:
50% heterozygous 2014
50% homozygous 2013
