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).
Which phenotype pairing can the genotypes of the individuals be directly known?
The phenotype pairings which the genotypes of individuals be directly known are homozygous recessive.
Breeding an individual of dominant phenotype with a homozygous recessive individual to determine the individuals genotype?
testcross
Are sepia eyes a recessive trait in drosophila?
Yes they are
How would a recessive trait show up in a cross between two individuals with a dominant phenotype?
If both the individuals are heterozygous dominant then the probability of recessive (homozygous) phenotypic offspring would be 1:4
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.
Are lobe eyes a recessive trait in drosophila?
yes, vestigial wings are recessive and autosomal.
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.
How can albinism in plants keep occurring if they cannot reproduce?
because the recessive allele is still present in heterozygous individuals. these individuals have one dominant allele and so show the dominant phenotype but they are capable of producing offspring with the recessive condition
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).
Why do we call some alleles dominant?
because it dominates the 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.
