160 homozygous dominant individuals and 480 heterozygous individuals

What is the type of allele that only effect the phenotype in the homozygous chromosome?
Recessive. Dominant alleles are expressed in both homozygous and heterozygous individuals (DD or Dd), but recessive alleles are only expressed in homozygous individuals (dd).
Is a yellow body a recessive trait in drosophila?
yes it is, and its on an autosomal chromosome
What do dominant and recessive alleles have in common?
Alleles are different types of a gene. Each gene controls a characteristic and they is usually a recessive allele and a dominant one. The main similarity is that they both control a certain characteristic!
If two genes in a gene pair are for the same trait what will that trait be?
The question should be "If two alleles for a gene are the same, what phenotype will the organism have?" Answer: If the two alleles are for the dominant phenotype, the organism will exhibit the dominant phenotype. If the two alleles are for the recessive phenotype, the organism will have the recessive phenotype.
Why is it that a person with an allele for a particular trait may not have a phenotype that shows the trait?
a dominant allele will express its trait , as well as be carried by the person. the word carrier is commonly used for a person who bears an allele which does not express itself(i.e. a recessive gene).
Are lobe eyes a recessive trait in drosophila?
yes, vestigial wings are recessive and autosomal.
Are sepia eyes a recessive trait in drosophila?
Yes, sepia eyes in Drosophila are a recessive trait. The sepia eye color phenotype is caused by a mutation in the gene that encodes the enzyme dopachrome isomerase, resulting in the brown eye color characteristic. Two copies of the mutated gene are required to exhibit the sepia eye color phenotype.
Breeding an individual of dominant phenotype with a homozygous recessive individual to determine the individuals genotype?

The following seed phenotype a showed up in a generation of plants. Which alleles are recessive?
To determine which alleles are recessive in the seed phenotype, you would need to compare the phenotype of the plants with known dominant phenotypes. Typically, if a phenotype appears in a generation that resembles the parents but differs from the dominant traits, those traits associated with the appearance of phenotype "a" are likely recessive. Observing the inheritance patterns in subsequent generations can further clarify which alleles are recessive based on the phenotypes that re-emerge when homozygous recessive individuals are bred.
How would a recessive trait show up in a cross between two individuals with a dominant phenotype?
In a cross between two individuals with a dominant phenotype but carrying a recessive trait, the recessive trait would not be visibly expressed in the offspring (since they don't inherit two copies of the recessive allele). However, they would be carriers of the recessive trait, meaning they could pass it on to future generations.
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.
What is phenotype of Rr?
It is Dominant. R is the dominant and r is the recessive. The dominate trait shadows the recessive trait. It is Dominant. R is the dominant and r is the recessive. The dominate trait shadows the recessive trait. Is dominant. dominant can be RR or Rr. but when its recessive its rr.
Are full wings a recessive trait in drosophila?
Yes -Dr. Who
A man has one recessive allele and one dominant allele. what is his phenotype?
He would have the recessive phenotype for that trait.
When inheritance of a particular trait follows a pattern of what individuals that are heterozygous for the trait have the same phenotype or physical characteristic as individuals who are homozyg?
This type of inheritance represents alleles at the same locus where one is recessive to the other. The dominant phenotype occurs in all heterozygous offspring as well as the homozygous dominant offspring. This yields a 3:1 phenotype and a 1:2:1 genotype.
What was the radio of dominant to recessive phenotype in the F2 generation of Mendel's experiment?
The ratio of dominant to recessive phenotype in the F2 generation of Mendel's experiment was 3:1. This means that for every 3 individuals expressing the dominant trait, there was 1 individual expressing the recessive trait.
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.
