If 675 plants resulting from the cross display a trait controlled by a dominant allele how many plants will show the trait controlled by the recessive allele?
In a gene loci there can be four combinations of 2 alleles. Suppose these possible allele combinations are called D for dominant and R for Recessive. The possible combinations for two of them are DD, DR, RD and RR. Wherever the D occurs the dominant trait will be displayed. There is only 1 where the recessive trait is displayed and this is the last or RR case. There must be 3 times the number of cases of the dominant trait as the recessive so the recessive trait is displayed in 675 / 3 cases or 225
What else can I help you with?
What gene won't display its trait in the prescience of a dominate trait?
A recessive gene will not display its trait in the presence of a dominant trait. A recessive gene only expresses its trait when paired with another copy of the same recessive gene.
What percentage of the offspring will most likely show the dominant trait?
More information is needed. The percent of offspring that will display the recessive trait from parents with Hh and HH will be different than the percent of offspring that will display the recessive trait from parents with hh and Hh.
Do Parents with the dominant phenotype cannot have offspring with the recessive phenotypeous for a trait that is?
No. Parents with the dominant phenotype might be heterozygous in their genotype. This means they could carry both the dominant and recessive allele for a trait. So they could both pass the recessive allele to an offspring, who would then have the homozygous recessive genotype and recessive phenotype.
In pea plants green pod color is controlled by a dominant allele Yellow is controlled by a recessive allele Explain why a plant with yellow pods can never be a hybrid?
A plant with yellow pods can never be a hybrid because yellow pod color is controlled by a recessive allele, meaning the plant must inherit two copies of this allele to display the yellow color trait. Therefore, a plant with yellow pods necessarily has two copies of the recessive allele and cannot have a dominant allele for green pods.
What does does heterozygous mean?
Heterozygous means that you are carrying 1 dominant trait and 1 recessive trait.If an allelic pair has one dominant and other recessive gene it is called 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 gene won't display its trait in the prescience of a dominate trait?
A recessive gene will not display its trait in the presence of a dominant trait. A recessive gene only expresses its trait when paired with another copy of the same recessive gene.
A living thing with a dominant and recessive gene for a trait?
A living thing with a dominant and a recessive gene for a trait is heterozygous. This individual will display the dominant phenotype for that trait but may have offspring that display the recessive trait.
Why is it possible that a majority of people may display a recessive trait?
It is possible for many people to display a recessive trait because the people have two recessive genes. Dominant simply means it will trump a recessive gene, it does not mean it is the most widely seen gene in a species.
What percentage of the offspring will most likely show the dominant trait?
More information is needed. The percent of offspring that will display the recessive trait from parents with Hh and HH will be different than the percent of offspring that will display the recessive trait from parents with hh and Hh.
In the F2 generation in Mendel's experiment's the ratio of dominant to recessive traits was?
The ratio of dominant to recessive traits in the F2 generation of Mendel's experiments was 3:1. This is known as the phenotypic ratio for a monohybrid cross, where three individuals display the dominant trait for every one individual displaying the recessive trait.
How can you determine the genotype of a plant that display the dominant form of a trait?
Do a testcross with a homozygous recessive plant.
Do Parents with the dominant phenotype cannot have offspring with the recessive phenotypeous for a trait that is?
No. Parents with the dominant phenotype might be heterozygous in their genotype. This means they could carry both the dominant and recessive allele for a trait. So they could both pass the recessive allele to an offspring, who would then have the homozygous recessive genotype and recessive phenotype.
How do you prove gene dominance?
When two heterozygous organisms are mated, approximately 75% of these organisms should display the trait if it is dominant. 25% would display the recessive gene. If these numbers are very far off, chances are the gene you were testing was not a dominant trait.
The second generation phenotypes resulting from the cross of true-breeding monohybrid pollination will display a ratio of?
3:1 ratio of dominant to recessive phenotypes.
If a baby goat received dominant gene for curly hair from one parent and recessive gene for straight hair from the other which trait will the baby goat display?
curly hair, as the dominant gene overrules the recessive gene I THINK :)
What does does heterozygous mean?
Heterozygous means that you are carrying 1 dominant trait and 1 recessive trait.If an allelic pair has one dominant and other recessive gene it is called heterozygous.
