Recessive
The FALSE statement is "A phenotype determines genotype." In reality, it is the genotype that determines the phenotype, as the genetic information (allele combinations) present in an individual's DNA influences their observable traits.
The phenotype for YySs would depend on the specific traits controlled by the Y and S genes. Without knowing the specific traits and their dominance or recessiveness, it is not possible to determine the exact phenotype. Each allele (Y and S) will contribute to the overall phenotype in conjunction with any other alleles present at the respective loci.
The phenotype that is present in most individuals in nature is typically the wild type phenotype, which is the most common and often the ancestral form of a trait within a population. It is favored by natural selection due to its adaptability and overall fitness for survival in the environment.
The observable expression of genes present in an organism is referred to as the phenotype. This includes both physical traits, such as eye color or height, as well as behavioral characteristics. Phenotypes result from the interaction between an organism's genetic makeup and its environment.
The genotype AA represents a homozygous dominant genotype. The capital letter "A" represents the dominant allele, while the lowercase letter "a" would represent the recessive allele. If both dominant alleles are present in a genotype (homozygous dominant) then the phenotype is "A" phenotype. If one dominant allele and one recessive allele are present (heterozygous dominant) then the phenotype is "A". Finally, if both recessive alleles "a" are present (homozygous recessive) then the phenotype is "a". Therefore, the answer to your question is the genotype AA would result in an "A" phenotype because the genotype is homozygous dominant.
The phenotypes present in the F1 generation depend on the phenotypes of the parental generation (and the environment). The F1 generation will display the dominant trait(s). For example, if T is tall and t is short, in the cross TT X tt the F1 generation will have the phenotype corresponding to the T allele (tall).
No. Genotype is the combination of genes present in an organism. It consists of alleles whose visible characteristics is called phenotype. An organism's phenotype is visible and not the genotype as you just can't see a person and tell what kind of genes are present in the organism.
All of the F1 generation are heterozygous, therefore 100% exhibit the dominant phenotype. The F2 generation has a ratio of 1 homozygous dominant: 2 heterozygous: 1 homozygous recessive. This results in a phenotypic ratio of 3 dominant: 1 recessive.

you mean phenotype, and its dominant alleles
