For a recessive trait to be expressed in a generation of offspring an individual must be a?

Homozygous


When is a recessive allel expressed in offspring?

A recessive phenotype is expressed in an offspring that has a homozygous recessive genotype for that trait.


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 are recessive expressed in?

homozygous organisms


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.


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.


If a dominant homozygous reproduced with a heterozygous could their offspring be recessive?

Let's see what combinations can be formed.HH, HH, Hh, Hh.So, yes their offspring can contain the recessive allele.(THe offspring can be a carrier of the recessive allele.)However, since it is impossible for the offspring to be homozygous recessive,the recessive trait/gene will not show in the offspring's phenotype.Hope that helps!


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.


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 dominant recessive?

There is dominant and there is recessive. There is no dominant recessive. A dominant gene will always be expressed when present, such as in the homozygous dominant genotype (RR), or heterozygous genotype (Rr). A recessive allele is only expressed when the genotype is homozygous recessive (rr).


If a test cross between a homozygous recessive and heterozygous allele will yield what percent of offspring as homozygous recessive?

25%


What is the ONLY genotype that can produce a recessive phenotype?

Only a homozygous recessive individual will have the phenotype created by two recessive alleles.Since the term produce might indicate the production of offspring parents that can only produce offspring with a recessive phenotype must both have homozygous recessive genotypes.
