A phenotype is a physical characteristic. For a human an observed phenotype example would be hair colour (e.g brown) or eye colour (green). An observed phenotype is a physical characteristic that can be seen directly or indirectly (internal organs) caused by an individual's genotype.

Diagram that indicates all possible genotypes of a genetic cross?
punnett square
In a punnett square the letters within the little boxes represent?
offspring genotypes
Can two organisms have different genotypes but the same phenotype?
One way is if an allele for the gene in question is dominant. Homozygotes for the dominant allele and heterozygotes will both have the same phenotype.Organisms have the same phenotype, or physical characteristics. They do not, however, have the same genotype, or genetic makeup. If T represent tall, and t represnts short then the organism will have the genotypes TT and Tt. If you make a Punnett square you will have the same phenotype but different genotypes. Unless some weird mutation occurs....
Who observed the first living cell?
Anton Von Leeuwenhoek observed the first living cell in around 1674,although Robert Hooke observed a dead cell in 1663.
How much do the expected genotypes of 100 offspring with the observed genotypes disagree?
If the expected genotypes match the observed genotypes perfectly, there should be no disagreement. If there is disagreement, it can be quantified using a statistical measure such as the chi-squared test to determine the degree of deviation between the expected and observed genotypes. The larger the difference between the expected and observed genotypes, the greater the disagreement.
Describe how phenotypes can be used to predict genotypes in a pedigree?
By observing the phenotypes of individuals in a pedigree (such as their physical characteristics or traits), one can infer the genotypes that may be responsible for those traits. By looking at patterns of inheritance within the pedigree, such as autosomal dominant, autosomal recessive, or X-linked inheritance, one can make educated guesses about the genotypes of individuals based on their observed phenotypes. However, the presence of genetic variability, incomplete penetrance, or phenocopies can complicate the prediction of genotypes solely based on phenotypic information.
What was the result when Morgan mated fruit flies with the genotypes?
When Thomas Hunt Morgan mated fruit flies with specific genotypes, he observed deviations from the expected Mendelian ratios, indicating that certain traits were linked on the same chromosome. This led to the discovery of genetic linkage and the concept of gene mapping.

Which genotypes have dominant phenotypes?
The genotypes in which one or more alleles is dominant.
If the parent genotypes are Aa and Aa is there only two possible genotypes among the offspring?
No, there are more than two possible genotypes among the offspring when both parent genotypes are Aa. The potential genotypes for the offspring are AA, Aa, and aa, resulting in a total of three different genotypes. The expected ratio from a Punnett square for this cross is 1 AA : 2 Aa : 1 aa.
What are the possible genotypes of the gametes in a genetic cross involving the keyword "genotypes"?
The possible genotypes of the gametes in a genetic cross involving the keyword "genotypes" are determined by the specific alleles present in the parents. These genotypes can be represented by different combinations of alleles, such as homozygous dominant (AA), homozygous recessive (aa), or heterozygous (Aa).
What was the result when Morgan mated fruit flies with the genotypes XrYr and XrY?
When Morgan mated fruit flies with the genotypes XrYr (homozygous for recessive traits on X and Y chromosomes) and XrY (heterozygous for the X chromosome), he observed a 1:1 ratio of offspring. The offspring would consist of XrYr and XrY genotypes, leading to a mix of phenotypes that correspond to the traits associated with those alleles. This experiment helped elucidate the principles of sex-linked inheritance in fruit flies.
How many genotypes do you receive from your parents?
People receive a total of 46 genotypes from their parents.
What are the possible genotypes for blood type A?
The possible genotypes for blood type A are AA and AO.
What term can describe the genotypes of the p generation?
The term "parental genotypes" can describe the genotypes of the P generation in a genetics experiment. These genotypes serve as the initial individuals crossed to produce offspring with specific traits of interest.
Does natural selection act on genotypes?
Indirectly, yes it does. But it can only act on genotypes through their phenotypes.
