Chromosomes are made of DNA and protein. DNA is the genetic material that determines the genotype and phenotype of a person. The phenotype is the genes that are expressed and observable.

To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is homozygous recessive. A monohybrid cross of two individuals that are heterozygous for a trait exhibiting complete dominance would probably result in a phenotype ratio is 3 dominant 1 recessive.
The paired chromosomes that determine an individual's gender are called sex chromosomes.
The sex of an organism is determined by the combination of sex chromosomes they inherit. In humans, individuals with two X chromosomes are female, while individuals with one X and one Y chromosome are male. Other organisms may have different combinations of sex chromosomes that determine their sex.
The chromosomes that determine an individual's biological sex are called the X and Y chromosomes.

It is a false statement that "phenotype determines genotype". In fact, it is the opposite. A genotype is the genetics or "instructions" that determine the phenotype. The phenotype is the actual appearance, ex: blue eyes, that is created by a given genotype.
The physical appearance of the entire set of chromosomes of a given animal is a phenotype. A phenotype is a trait that you can observe like the color of a persons eyes.
In genetics, alleles can be classified as either dominant or recessive. The term "homologous" refers to the pairing of chromosomes in meiosis. Whether an allele is dominant or recessive depends on its effect on the phenotype when paired with another allele. Homologous chromosomes do not determine the dominance of an allele.
xy chromosomes mostly fall on male gender.

No, genotype actually determines phenotype.
