Is a widows peak a trait controlled by many genes?
A widows peak is controlled by one gene that is passed on from both parents. In this case lets say your parents both have a dominant allele for a widows peak(A) so in that case, you would have a 100% chance of being born with one.
What are genotype determinants?
'Genotype determinants' are just another set of words to describe alleles, because an allele is what determines your genes. An allele is basically an alternative forms of a gene. Humans have 2 forms (2 alleles) for each gene (except in sex cells) one from your mom, one from your dad. The allele occupies a fixed position (locus) on the chromosome and, depending on whether or not it is dominant or recessive, it determines the phenotypes- or how the gene will be physically expressed. A Example of recessive alleles: widows peak- you need two 'widows peak' alleles to have that feature physically expressed. If you have 1 widows peak allele and another for 'no widows peak' then the dominant form will be expressed, in this case it means you will not have a widows peak.
Dominant gene plus Dominant gene?
It would be definite that you have that gene or trait.
To have blond hair do both of your genes have to be for blond hair?
not necessarily.ok there are two parents each giving the child one gene. if one gene is recessive and one is dominant the dominant gene will decide the hair color. example the recessive gene is black hair and the dominant gene is blonde the child will most likely have blonde hair because the dominant gene is blonde hair. the dominant gene masks the recessive gene
What is a dominant gene and what is a recessive gene?
Recessive gene is one which is supressed and do not show their characteristics and dominant gene is one which show their characteristics for example if a father has brown hair and mother has black hairs and if their son has black hair then in this case gene which has characteristics of black is dominant and the other which has characteristics of brown colour is recessive

Is the Huntingtons gene inherited as a dominant or ressisive gene?
It is inherited by a dominant gene.
When one gene expresses itself over another the former gene is said to be the DNA?
The gene that expresses itself over the other is Dominant. The former gene is recessive.
What is a homozygus?
When two cells have the same gene type then they are considered homozygous.
