What ultimately determines the phenotype of an individual?
Phenotype is what traits are expressed by the organism. So what ever is the dominant Genotype of the organism will determine the Phenotype. For example a dominant R gene will be the Phenotype in RR and Rr. However, if the organism has two recessive rr then the recessive gene will determine the Phenotype.
How do you use genotype and phenotype in a sentence?
In genetics,the phenotype is when genes combine to determine dominant traits
Breeding an individual of dominant phenotype with a homozygous recessive individual to determine the individuals genotype?
testcross
What is the phenotype of AAA?
It's impossible to say without more information. The genotype AA is called homozygous dominant for the trait that is encoded by the letter A (or a). Whatever trait A stands for on your homework, the answer is the dominant one is expressed in the phenotype.
To determine the genotype of an individual that shows the dominant phenotype you would cross the individual with one that is?
Homozygous recessive.
To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is?
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.
Can a child be afflicted with a dominant trait if both her parents have a normal phenotype Why or why not?
YES SOMETIMES THAT IS NOT LIKELY.
Why is a dominant allele called dominant apex?
because it dominates the phenotype
Is phenotype determine genotype false?
Yes, this is false. It's genotype that determines phenotype. e.g. If you have the dominant gene for brown eyes and the recessive gene for blue eyes (genotype) you will have brown eyes (phenotype)
Is Aa and AA a dominant phenotype?
Yes, both Aa and AA genotypes represent the dominant phenotype for a specific trait. The presence of at least one dominant allele (A) will result in the dominant phenotype being expressed.
Is it possible to determine the genotype of a plant with a dominant phenotype the trait?
NO, because a dominant phenotype could either be homozygous or a heterozygous.so unless you are sure about the genotype of parents we can't determine it...but we can determine the genotype of a person showing reccessive phenotype, as a recessive trait always expresses itself in a homozygous condition..Read more: Is_it_possible_to_determine_the_genotype_of_a_person_showing_a_dominant_phenotype
Is the phenotype which determine RH?
Genotype determines the rh phenotype. The two alleles for rh factor are rh+ (rh positive) and rh- (rh negative). The rh+ allele is dominant.
