The probability of a homozygous recessive offspring resulting from a cross between two homozygous dominant individual is?

It depends on the parents. The parent could have two dominant genes which would give a 0% chance of the offspring being recessive. The only way that the offspring could have a recessive characteristic is if the both parents have one dominant and one recessive gene, a 25% chance. The chance that both parents would pass on the recessive gene (if they have one dominant and recessive gene) is also 25%, because there is a 50% chance for each parent.

How do two heterozygous organisms produce on offspring with a recessive phenotype?
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.
How would a recessive trait show up in a cross between two individuals with a dominant phenotype?
If both the individuals are heterozygous dominant then the probability of recessive (homozygous) phenotypic offspring would be 1:4
What is the difference between a homozygous dominant homozygous recessive and heterozygous individual?
They are the same
What is the probabilty that the offspring of a homozygous domiant idiviual and a homozygous recessive indiviual will exbhit the domaint phenotype?
100% heterozygous dominant
What is the difference between a homozygous trait and a heterozygous trait and can you please provide an example for each?
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.
What is the probability that the offspring of a homozygous dominant individual and a homozygous recessive individual exhibit the dominant phenotype?
Given those conditions, the offspring have a 50% chance of demonstrating the dominant phenotype and a 50% chance of demonstrating the recessive phenotype.
In crossing a homozygous recessive with a heterozygote what is the chance of getting a homozygous recessive phenotype in the F1 generation?
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.
What is the probability that an individual heterozygous for a cleft chin and individual homozygous for chin without cleft will produce offsprings that are homozygous recessive for chin without cleft?
The probability that an individual heterozygous for a cleft chin and an individual homozygous for a chin without a cleft will produce offspring that are homozygous recessive for a chin without a cleft is fifty percent. You can calculate this by making a Punnet square.
What is the probability of 2 heterozygous individuals producing a heterozygous recessive offspring?
The probability is 50%. There are four probabilities: dominant homozygous, recessive homozygous, or heterozygous.
What is the probability that an offspring will be homozygous recessive?
well, it depends on the genes of the parents
What is the percentage of offspring that will exhibit the dominant trait from A crossing of A homozygous dominant and homozygous recessive individual?
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.
What is the probability of offspring for 2 heterozygous dogs?
There are 3 probabilities: dominant homozygous, recessive homozygous, or heterozygous.
What is the probability of 2 heterozygous individuals producing a homozygous recessive offspring?
25%
What is the probaility that the offspring of a homozygous dominant individual and a homozygous recessive individual will exhibit the dominant phenotype?
100 percent.
An individual heterozygous for a trait and an individual homozygous recessive for the trait are crossed and produce many offspring?
The offspring has a 50% chance of the dominate trait (while being heteroygous) and a 50% chance of having the recessive trait ( homozygous recessive).
For a recessive trait to be expressed in a generation of offspring an individual must be a?
Homozygous
What is the name for a cross between an individual of unknown genotype and a homozygous recessive?
A cross between a homozygous recessive and an individual of unknown genotype is called a test cross.The homozygous recessive can only pass on a recessive allele to the offspring, and so any recessive in the other parent will show up in the phenotype (detectable characteristics) of some of the offspring.
