How can two individuals that have the exact same genotype for a certain trait but not identical when it comes to that trait be possible?

I have the same Bio Question. I THINK it depends on how your DNA reads the genes available.

What is punnett square use for?
A Punnett square is used for determining all possible combinations for an offspring of one trait from two parents. Basically it is the experimental crossbreed between two individuals that shows the probability of the offspring inheriting a certain genotype.
Which best describes probability A. The genotype ratio for a certain trait B. The likelihood that something will happen C. The most likely possible outcome D. The number of offspring with a trait?
b the likelihood of an event occurring apex
How does genotype affect phenotypes?
They are related to each other because...Genes and alleles are the traits inside an object, when using a punnet square, we take the genotype out of that object to make experiments.
How do you answer apunnet square question?
A punnet square is typically used in topics involving genetics, genetic variation and gene expression. A punnet square is a simple way of showing the what possible genotypes are using the genotypes of the parents. This way we can identify the ratio and also identify the chance of having a certain offspring compared to it's recessive/dominant counterpart. To answer a punnet square question you must draw a grid. The easiest grid is usually a 3 by 3 grid. In the top squares put the fathers genotype and in the side squares put the mothers genotype. Then match them up with capitals coming first and you now have possible allele combinations and your genotype and phenotype ratio.

Why natural selection acts on the phenotype rather than genotype?
natural selection is a passive prosess . the mechanism of some individuals to be selected more than others is because they fit their environment more. and phenotype shows the fitness .
Is a gene a genotype that is not mixed?
No. 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 is the pthenotype for each genotype?
Genotypes are the specific allele combinations that an individual contains pertaining to a certain trait. Phenotypes are what is expressed due to the genotype. (recessive/dominant/codominant)
What is the probabilty of certain colors in bag of mm?
The bags do not all contain identical mixes, not is each colour represented equally. It is therefore, not possible to provide a useful answer.
What is a testcross in biology?
a cross between an organism whose genotype for a certain trait is unknown and an organism that is homozygous recessive for that trait so the unknown genotype can be determined from that of the offspring
What does the term allele mean as is used in genetic crosses?
The term allele is different from a genotype because an allele can be singular, but the alleles that an individual (diploid organism) has at a certain locus are called a genotype.
Which best describes probability A. The genotype ratio for a certain trait B. The likelihood that something will happen C. The most likely possible outcome D. The number of offspring with a trait?
b the likelihood of an event occurring apex
What is a testcross?
Gregor Mendel devised the fundamental tool of the test cross. It is an experimental cross of an individual organism of dominant phenotype but unknown genotype and an organism with a homozygous recessive genotype .

In cattle black coat is dominant to white coat color a farmer has a black male of undetermined genotype how can the farmer determine the genotype of the male?
One way to determine the male's genotype would be to breed him to females with a known genotype of Black-Black. If any resultant calves were born with a white coat, you would then know that the male were Black-White. If calves were consistently black coated, you could be fairly certain he was also of the Black-Black genotype.
Do living things on earth share certain identical sequences of bases on their genome?
No
