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.


What is crossing a homozygous dominant or homozygous recessive with a heterozygous?

There is a 50% chance of a homozygous dominant and a 50% chance of a heterozygous.


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.


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.


What is the difference between a herezygous and a homozygous?

"Heterozygous" and "homozygous" are terms that refer to alleles, which, in genetics determine what trait, from which parent, will appear in the offspring. Alleles can be either Dominant or Recessive. Every organism has two alleles, which can both be dominant, both recessive, or one of each.So,If an organism heterozygous, it has one recessive and one dominant allele.If an organism is homozygous then both of its alleles are the same; you need to specify if they are homozygous recessive (both alleles are recessive) or homozygous dominant (both alleles are dominant).

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 probaility that the offspring of a homozygous dominant individual and a homozygous recessive individual will exhibit the dominant phenotype?

100 percent.


What is crossing a homozygous dominant or homozygous recessive with a heterozygous?

There is a 50% chance of a homozygous dominant and a 50% chance of a heterozygous.


How can offspring inherit a recessive trait?

An offspring can inherit a recessive trait if both of its parents are homozygous for the dominant allele.


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.


What is the probability of offspring for 2 heterozygous dogs?

There are 3 probabilities: dominant homozygous, recessive homozygous, or heterozygous.


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.


A parent that is homozygous for a dominant trait is crossed with a parent that is homozygous for the recessive trait What percentage of the offspring will display the dominant trait?

100% of the offspring will display the dominant trait because the homozygous dominant parent can only pass on the dominant allele. The offspring will inherit one dominant allele from the dominant parent and one recessive allele from the recessive parent, resulting in a heterozygous genotype expressing the dominant trait.


In which offspring does a dominant trait appear?

if a trait is recessive, it can only be expressed if its other trait is recessive as well. If the other trait in the genotype is dominant, it will block the recessive factor. But if both are recessive, they will be able to be seen in the offspring.


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 of 2 heterozygous individuals producing a heterozygous recessive offspring?

The probability is 50%. There are four probabilities: dominant homozygous, recessive homozygous, or heterozygous.
