How can two plants have different genotypes having the same phenotype?
The simplest way that two plants can have different genotypes, but the same phenotype, is if they both have a dominant allele for the same trait. For example, the genotypes Pp and PP, will both produce the phenotype created by P (for example, pink coloured petals). This is because P is dominant to p, and will always be expressed. Other ways that the same phenotype can be created from different genotypes are when the environment affects the traits, or when the trait is controlled by more than one gene.
How is incomplete dominance expressed in phenotype?
In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
When traits are inherited in an incomplete dominance pattern what is true about the phenotype of the heterozygotes?
A trait that exhibits incomplete dominance, is one in which the heterozygous offspring will have a phenotype that is a blend between the two parent organisms. An example of this is when a homozygous red sweet pea flower crossed with a homozygous white sweet pea flower, their offspring will be heterozygous and have the pink phenotype, rather than either red or white.
Explain how interactions between genes and the environment can affect phenotype-?
Interactions between genes and the environment can influence phenotype by modifying gene expression levels. Environmental factors like diet, stress, and exposure to pollutants can impact gene regulation, leading to different phenotypic outcomes. For example, identical twins with the same genetic makeup can exhibit differences in traits like height or disease susceptibility due to environmental influences.
What ultimately determines the phenotype of an individual?
The phenotype of an individual is ultimately determined by a combination of their genetic makeup (genotype) and environmental factors. Genes provide the instructions for building and maintaining an organism, while the environment can influence the expression of these genes. The interaction between genetics and environment shapes the physical and behavioral characteristics that make up an individual's phenotype.
What are some similarities between phenotype and genotype?
Genotype codes for phenotype. Phenotype is the expressed trait, for example, black fur. The genome that codes for black fur would be BB for example
What is a description for phenotype and example?
The phenotype is a physical characteristic that is expressed by the genes. ----- An example of a phenotype is human blood group.

What is phenotypic variation?
Phenotype variation is slight variations in a phenotype that are caused by the expression of an organism's genes or the influence of environmental factors. A species can have several different phenotypes within it.

Environmental factors like diet, stress, and exposure to pollutants can impact gene regulation, leading to different phenotypic outcomes. For example, identical twins with the same genetic makeup can exhibit differences in traits like height or disease susceptibility due to environmental influences.
The example of the English peppered moth demonstrates what?
B) that a harmful phenotype may become an advantageous phenotype when the environment changes
What is the outward appearance of a trait called?
phenotypeThe physical appearance of a trait is called a phenotype, not to be confused with a genotype( which is your genetic makeup) The way I remember is phenotype and physical both start with a p, and genotype and genetic both start with a g.

Why is phenotype more important than genotype?
Phenotype is the displayed characteristics of the organism, as opposed to the genotype, which is the gene sequence of the organism. Phenotype is important because it includes everything that the organism can do. Whether a plant is pink or red, an example of phenotype, can influence whether or not a bee will be attracted and pollenate it. The presence of cystic fibrosis, a debilitating disorder in humans, is caused by genotype but expressed through phenotype, and can be the difference between death at twenty or a long life to eighty.
How is genotype and phenotype compared?
Genotype is the allele combination and phenotype is the physical appearance of the result of the genotype. Genotype for tallness may be: Tt Phenotype example: Brown hair, blue eyes, widow's peak, etc.
