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 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 cross should a scientist perform in order to determine if the organism is heterozygous or homozygous dominant?

The scientist should perform a test cross between the organism and a homozygous recessive organism. If all offspring show the dominant trait, the original organism is homozygous dominant. If some offspring show the recessive trait, the original organism is heterozygous.


If 240 plant offspring were produced from crossing two heterozygous plants how many would be homozygous?

Out of the 240 offspring, approximately 60 would be homozygous (25% of 240). This is because when two heterozygous plants are crossed (Aa x Aa), the Punnett square shows that 25% of the offspring will be homozygous dominant (AA), 50% will be heterozygous (Aa), and 25% will be homozygous recessive (aa).


What is the probabilty that the offspring of a homozygous domiant idiviual and a homozygous recessive indiviual will exbhit the domaint phenotype?

If one parent is homozygous dominant (AA) and the other parent is homozygous recessive (aa), all offspring will inherit one dominant allele and display the dominant phenotype. Therefore, the probability of their offspring exhibiting the dominant phenotype is 100%.

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 percentage of the offspring will have green seeds?

it depends.if you have a homozygous mated with a heterozygous,green being dominant,you would get 50percent


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 probability of offspring for 2 heterozygous dogs?

The probability of offspring for two heterozygous dogs (Aa x Aa) is 25% homozygous dominant (AA), 50% heterozygous (Aa), and 25% homozygous recessive (aa) based on Mendelian genetics principles.


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.

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.


What cross should a scientist perform in order to determine if the organism is heterozygous or homozygous dominant?

The scientist should perform a test cross between the organism and a homozygous recessive organism. If all offspring show the dominant trait, the original organism is homozygous dominant. If some offspring show the recessive trait, the original organism is heterozygous.

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.
