Answer:
The two previous horses were heterozygous recessive. They carried the genes for OWLs however the genes were recessive therefore the dominate gene gave it's phenotype. I would tell the horse owner that it would be best to breed using different horses, however breeding with the same horses may still lead to healthy results.
Explanation:
This answer revolves around Mendel and his studies. The parents had the gene coding for the disease however it was "out-shined" by the dominant gene, in this case the healthy gene. Therefore the two parents were healthy. Now according to Mendel's research and his punnet square (I suggest you look into it for further explanation) if two heterozygous recessive creatures were to have an offspring there is a high chance that one of their offspring will have the disease seeing as babies in general will receive an allele from the mother and one from the father. So a child having
The principles of genetics were given by Mendel in which he showed how the genes get inherited from the parent to their offspring.
1. The foal was born with OWLs because the parent horse contained the heterozygous recessive genes.
The recessive genes got masked but the dominant gene causing the disease passed to the fowl and caused the OWLs disease.
2. The newborn baby girl will have a XX chromosome and the possibility of having kids further will be 50% odds for a boy and another 50% for a girl.
- The female parent contributes the X chromosome while the male donates the X and Y chromosome.
- If the child has XX chromosome from each parent then it will be a girl while the child having XY chromosome from each parent will be a boy.
