0 (there is no chance it will be short since tall is dominant over short).
Hope this helps!

The probability is 50%. There are four probabilities: dominant homozygous, recessive homozygous, or heterozygous.
25% or 1 out of 4 (You can use a Punnett Square for that and/or other questions like it.)
R represents the dominant round allele, and rrepresents the recessive wrinkled allele. :D
The frequency of the homozygous dominant genotype.
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.
There are 3 probabilities: dominant homozygous, recessive homozygous, or heterozygous.
The probability is 50%. There are four probabilities: dominant homozygous, recessive homozygous, or heterozygous.
There is a 50% chance of a homozygous dominant and a 50% chance of a heterozygous.
There are two forms of Homozygous inheritance: Homozygous Dominant, and Homozygous Recessive. In order for two parents that are Homozygous to produce a Heterozygous offspring, one of them MUST be Homozygous Dominant, and the other MUST be Homozygous Recessive.
The homozygous dominant individual can only pass on the dominant allele and the homozygous recessive individual can only pass on the recessive allele, therefore all offspring will be heterozygous and have the dominant phenotype.
From the cross Aa x Aa, the probability of producing a homozygous dominant offspring is 1/4 or (0.25).
You get one homozygous dominant (TT), one homozygous recessive (tt), and two heterozygous (Tt).
Homozygous dominant (Ex:AA) Heterozygous (Ex:Aa) Homozygous recessive (Ex:aa)
100% heterozygous dominant
1/2 or 50%. The homozygous recessive gentoype contains two recessive alleles for the gene for a trait. So the homozygous recessive individual can pass on only recessive alleles to an offspring. The heterozygous individual has one dominant and one recessive allele for the gene for a trait. So the heterozygous individual can pass on either a dominant or a recessive allele to an offspring. So if an offspring inherits a recessive allele from the heterozygous parent, along with the recessive allele from the homozygous recessive parent, it will have the homozygous recessive genotype and phenotype.
If both the individuals are heterozygous dominant then the probability of recessive (homozygous) phenotypic offspring would be 1:4
a homozygous trait is when an offspring has either both dominant genes or both recessive genes from its parents. a heterozygous trait is when an offspring has both dominant and recessive genes. for example: a long-tailed cat is dominant and a short-tailed cat is recessive. the long-tailed cat (homozygous dominant) had offsprings with the short-tailed cat (homozygous recessive). by doing the punnett square, 100% of their offspring will be heterozygous.
