Zero. If it's RR that means it only contains the dominant allele
A recessive phenotype is expressed in an offspring that has a homozygous recessive genotype for that trait.
A homozygous genotype with both alleles being recessive is called a homozygous recessive genotype. This means that both copies of the gene are the same recessive allele, resulting in the expression of the recessive trait.
The genotype ff represents a homozygous recessive individual for a specific gene. This means that both alleles for the gene are the same and both are the recessive allele (f). This individual will exhibit the trait associated with the recessive allele.
An example of a heterozygous recessive genotype is when an individual carries one dominant allele and one recessive allele for a particular trait. One example could be a person with the genotype Aa, where "A" represents the dominant allele and "a" represents the recessive allele.
Recessive alleles are alleles that are masked or overshadowed by dominant alleles. In a heterozygous genotype, the recessive allele does not show its effects. Only in a homozygous recessive genotype does the recessive allele manifest its trait.
A genotype in which there are both a dominant and a recessive allele is called heterozygous.
This depends entirely on the genotype of the parents. The probability of getting a specific genotype is the probability of getting the correct allele from mother (1/2) multiplied by the probability of getting the correct allele from father (1/2) multiplied by the number of ways this can occur. The probability of getting a phenotype, if the phenotype is dominant, is the sum of the probability of getting two dominant alleles, and the probability of getting one dominant allele. If the phenotype is recessive, the probability is equal to the probability of getting two recessive alleles.

Yes, it is common practice to denote the dominant allele before the recessive allele when writing a genotype to highlight the dominant trait. For example, if the dominant allele is represented by "A" and the recessive allele by "a," the genotype for a dominant individual would be written as "AA" rather than "aa."
Yes, a recessive allele will be expressed if there is no dominant allele present in the genotype. This is because in the absence of a dominant allele, the recessive allele has the opportunity to be expressed in the phenotype.
The genotype ff represents a homozygous recessive individual for a specific gene. This means that both alleles for the gene are the same and both are the recessive allele (f). This individual will exhibit the trait associated with the recessive allele.
dominant allele before a recessive trait
An example of a heterozygous recessive genotype is when an individual carries one dominant allele and one recessive allele for a particular trait. One example could be a person with the genotype Aa, where "A" represents the dominant allele and "a" represents the recessive allele.
The genotype is homozygous recessive or the recessive trait is on the X chromosome and has no corresponding allele on the Y chromosome.
The allele not expressed would be recessive whilst the other is dominant. This would be the case in a heterozygous genotype. Hope this helps
No, TTT is not an example of a homozygous recessive genotype. In genetics, a homozygous recessive genotype would have two copies of the same recessive allele, such as tt. TTT would indicate a homozygous dominant genotype.
