When two cultives are crossed their offspring will be?

Their offspring will be heterozygous recessive.


To determine if a particular plant is homozygous or heterozygous you would have to test cross with a?

To determine if a particular plant is homozygous or heterozygous, you would need to perform a test cross with a homozygous recessive individual. If the offspring display the recessive trait, the original plant would likely be heterozygous. If all offspring exhibit the dominant trait, the original plant would likely be homozygous dominant.


To determine if a particular plant is homozygous or heterozygous you would have to test cross with a what?

To determine if a plant is homozygous or heterozygous, you would need to test cross it with a homozygous recessive plant. If the offspring show the recessive trait, the original plant is heterozygous; if all offspring show the dominant trait, the original plant is homozygous.


How many phenotypes can come from a heterozygous parent and a homozygous recessive parent?

Two types: A heterozygous parent (Aa) and a homoygous recessive parent (aa) can produce phenotypically dominate and phenotpically recessive offspring (with 50% genotypes Aa and the other 50% aa). If the genes are co-dominate then the offspring can have blended traits and recessive traits phenotypically.


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.

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

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

A test cross between a homozygous recessive and a heterozygous individual will yield 50% of offspring as homozygous recessive. This is because all the offspring will inherit one recessive allele from the homozygous recessive parent.

Heterozygous induviduals pass the dominant and recessive alleles to offspring


Individual heterozygous for a trait and an individual homozygous recessive for the trait are crossed and produce many offspring?

The offspring will all inherit one copy of the dominant allele (from the heterozygous parent) and one copy of the recessive allele (from the homozygous recessive parent). This results in all offspring being heterozygous for the trait.

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.

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 of 2 heterozygous individuals producing a homozygous recessive offspring?
