A gene is a part of the DNA that identifies the outcome of a certain trait or part of a trait.
A genotype is the actual definition of the gene for each individual.

What could cause a mutant fly embryo to develop two tail ends but no head?
This is called bicoid mutant phenotype, and is caused by a maternal effect gene which is a gene that, when mutant in the mother, results in a mutant phenotype of the offspring regardless of the offspring's genotype.
What is the physical representation of a gene called?
a gene is something that you get off your parents eg. your mum has brown hair and blue eyes and your dad has red hair and green eyes and so you have your mothers genes for your brown hair and your fathers green eyes
What is the genotype for males?
The genotype for males is: "XY"
How can an organism with a genotype Gg could have the same phenotype as an organism with the genotype GG?
Dominant alleles are expressed, even if a recessive allele is also present. In the notation used, a capital letter means a dominant allele - therefore the presence of a P (in either PP or Pp) means the organism will display the trait P creates.
Could 2 people with a widows peak have a child with a straight hairline and could 2 people with a straight hairline have a child with a widows peak EXPLAIN?
Yes to the first one, no to the second one. Firstly, widow's peak is caused by a dominant gene while a straight hairline is caused by a recessive gene. Let 'H' be dominant and 'h' be recessive. So for a dominant gene, the trait still will be expressed whether the genotype of the person is homozygous dominant(HH) or heterozygous(Hh). For a recessive gene however, the trait will only be expressed when the genotype of the person is homozygous recessive (hh). So two people with a widow's peak CAN have a child with a stright hairline, provided both of their genotypes are Hh. This is because by crossing their genotypes, they can have a possibility of having child with the genotype HH(widow's peak), Hh(widow's peak), and also hh(straight hairline). The ratio of these three possibilities however, are 1:2:1. So the odds of having a child with a straight hairline in this case is 1:3. If the two people who have widow's peak have the genotype HH or one of them HH and the other Hh, then the possibility of having a child with a straight hairline is 0. This is because by crossing their genotypes together, the genotype of the child will either be HH for the first case, and HH or Hh for the second case. For two people who have a straight hairline, the genotype of both will definitely be homozygous recessive (hh), thus child will definitely have the recessive gene. Therefore, it is not possible for two people with straight hairline to have a child with widow's peak.

What is recessive gene and dominant gene?
A dominant gene is always expressed if present, and the recessive gene is only expressed with the homozygous recessive genotype. For example, if the dominant gene is red (represented by the letter R) and the recessive gene is white (represented by the letter r), then a homozygous dominant organism's genotype will be RR, and its phenotype will be red. If the organism is homozygous recessive, then the genotype will be rr and the phenotype will be white. If the organism is heterozygous, then the genotype will be Rr, and the organism will be red.
What is the unknown genotype?
Heytoph is the name of the unknown genotype, i hope it works guys!

You can be a carrier of a recessive gene as part of your?
You can be a carrier of a recessive gene as part of your genotype.
Is phenotype determine genotype false?
Yes, this is false. It's genotype that determines phenotype. e.g. If you have the dominant gene for brown eyes and the recessive gene for blue eyes (genotype) you will have brown eyes (phenotype)
What an organsim genotype?
And Organism's genotype is the organism's specific combination of alleles in a any given gene.
