What does The presence of an allele for purple flowers will mask the presence of an allele for white flowers mean?
Purple is the dominant form of the allele.
What else can I help you with?
What was the result when Mendel cross pollinated true breeding purple flowering plants and true breeding white flowering plants?
He got purple flowers, because purple is dominant over white, and a plant with the combination of purple and white will be purple. P being the purple gene, p being the white, Pp will be purple, just like PP. Only pp will be white.
When purple is a dominant the white offspring of purple and white parents will be?
When purple is dominant and white is recessive, the white offspring of purple and white parents will be heterozygous for the purple gene. This means they will carry one purple allele and one white allele, but display the purple trait due to its dominance.
You cross a pure-breeding plant with red flowers and a pure -breeding plant with white flowers. All the offspring have red white speckled flowers. what type of allele relationship does this show?
You cross a pure-breeding plant with red flowers and a pure-breeding plant with white flowers. All the offspring have red and white speckled flowers. What type of allele relationship does this show?
How do you use Single Gene Trait in a sentence in biology?
The single gene trait for flower color in pea plants is determined by a pair of contrasting alleles, with one allele producing purple flowers and the other producing white flowers.
In sweet pea plant R is the allele for red flowers and r is the allele for white flowers a. If an RR plant and an rr plant are crossed what will be the outcome of their offsprings?
All of the offspring will be red, since each of the four offspring receive the dominant red allele (R). Therefore, the offspring will all have the genotype Rr and a phenotype of red.
In the pea plants the presence of an allele for purple flowers will mask presence of an allele for white flowers. What does that mean?
Gene responsible for purple color is dominant over white color.
Purple flowers are dominant to white flowers?
If purple flowers are dominant to white flowers, it means that a plant with one purple allele and one white allele will display the purple flower phenotype. The white flower phenotype would only be expressed if the plant inherits two white alleles.
How can 2 purple flowers make a white flower?
Two purple flowers can produce a white flower through a genetic phenomenon called incomplete dominance, where the dominant purple allele and recessive white allele both influence the flower's color. When two heterozygous purple flowers (Pp) are crossed, there is a 25% chance of producing a white flower (pp) due to the combination of alleles.
What was the result when Mendel cross pollinated true breeding purple flowering plants and true breeding white flowering plants?
He got purple flowers, because purple is dominant over white, and a plant with the combination of purple and white will be purple. P being the purple gene, p being the white, Pp will be purple, just like PP. Only pp will be white.
Which example shows complete dominance?
Complete dominance occurs when one allele completely masks the effect of another allele at the same gene locus. An example of this is the inheritance of flower color in pea plants, where the allele for purple flowers (P) is completely dominant over the allele for white flowers (p). In this case, both homozygous (PP) and heterozygous (Pp) plants will exhibit purple flowers, while only homozygous recessive (pp) plants will show white flowers. This clear masking of one allele by another is a hallmark of complete dominance.
What is complete dominace?
Complete dominance is a genetic phenomenon where one allele completely masks the effect of another allele at the same locus in a heterozygous individual. In this scenario, the dominant allele's traits are fully expressed, while the recessive allele's traits are completely obscured. This results in offspring showing only the phenotype associated with the dominant allele, regardless of the presence of the recessive allele. An example of complete dominance can be seen in Mendel's pea plants, where the dominant allele for purple flowers completely masks the recessive allele for white flowers.
A plan with one dominate and one recessive gene?
In genetics, a plan with one dominant and one recessive gene can be described by a heterozygous genotype, such as Aa, where "A" represents the dominant allele and "a" represents the recessive allele. The dominant gene will express its trait in the phenotype, overshadowing the recessive gene. For example, if "A" codes for purple flowers and "a" for white flowers, a plant with the genotype Aa will have purple flowers. This illustrates how dominant traits can mask the presence of recessive traits in an organism.
When purple is a dominant the white offspring of purple and white parents will be?
When purple is dominant and white is recessive, the white offspring of purple and white parents will be heterozygous for the purple gene. This means they will carry one purple allele and one white allele, but display the purple trait due to its dominance.
N an experiment with pea plants two purple flowered pea plants that are heterozygous for the alleles for flower color are crossed The results are offspring with purple flowers 25 offspring with wh?
The results suggest that the allele for purple flowers is dominant (P) and the allele for white flowers is recessive (p). The Punnett square for the cross would show a 3:1 ratio of purple to white flowered offspring, as predicted by Mendel's laws of inheritance. This indicates that the purple flower trait is dominant and the white flower trait is recessive.
You cross a pure-breeding plant with red flowers and a pure -breeding plant with white flowers. All the offspring have red white speckled flowers. what type of allele relationship does this show?

In pea plants individuals that are Pp for the allele that code?
In pea plants, individuals that are heterozygous (Pp) for a particular allele exhibit a phenotype influenced by both the dominant (P) and recessive (p) alleles. The dominant allele typically masks the effect of the recessive allele, resulting in the dominant trait being expressed. For example, if P represents purple flowers and p represents white flowers, Pp plants will display purple flowers. This demonstrates the principles of Mendelian inheritance where dominant traits prevail in heterozygous conditions.
Mendel saw purple flowers in the F generation but both purple and white flowers in the F How did this help him see that traits are inherited as discrete units?
Mendel's observation of the purple flowers in the F1 generation and both purple and white flowers in the F2 generation indicated that traits are inherited as discrete units called alleles. The presence of both traits in the F2 generation showed that the white flower trait was not lost and could reappear in later generations, demonstrating the concept of dominant and recessive alleles.
