In humans, the presence or absence of dimples is a trait controlled by a single gene What is the genotype of an individual who is heterozygous for dimples? yellow In pea plants, yellow seed color is dominant over green seed color The phenotype of an individual with a heterozygous genotype ("Yy") would be ______ a) is a carrier monohybrid cross
- [FREE] In humans, the presence or absence of dimples is a trait . . .
When an individual is heterozygous for dimples, it means they have one dominant allele for dimples and one recessive allele for no dimples The genotype is represented as 'Dd'
- Are facial dimples determined by genetics? - MedlinePlus
Dimples are usually considered a dominant genetic trait, which means that one copy of the altered gene in each cell is sufficient to cause dimples However, some researchers say that there is no proof that dimples are inherited
- Solved: In humans, the presence of absence of dimples is a trait . . .
Option 2: DI: This genotype includes two different genes, not alleles for the same gene Option 3: dd: This genotype is homozygous recessive, meaning the individual has two copies of the recessive allele
- Answer the 4 questions In humans the presence or - Studocu
A heterozygous individual carries two different alleles for a gene In this case, "D" could represent the allele for dimples (dominant), and "d" could represent the allele for no dimples (recessive)
- What Is the Genotype for Dimples? - Education
A dimple is a dominant trait Say John, who has two dominant dimple genes (DD), and Jane, who has two recessive dimple genes (dd), have a baby named Alice Alice will receive one allele
- in humans The presence or absence of dimples is a trait controlled by a . . .
From the Punnett square, we can see the possible genotypes of the offspring are: - DD (homozygous dominant for dimples) - Dd (heterozygous for dimples) - dd (homozygous recessive for no dimples)AnswerDetermine the genotypic ratio
- Single Gene Traits in Humans
The following is a list of some autosomal human traits that have been attributed to a single gene Although clearly other genes are involved, the inheritance of each of these phenotypic traits acts as if it were governed by a single gene
- Kirk Douglas has a prominent dimple in his chin and so does his son . . .
Kirk Douglas must have the genotype DD or Dd for dimples, as this trait is dominant and he has a dimple However, since his son Michael also has a dimple, but Michael's mother does not, Kirk must be heterozygous (Dd) for this trait
- Solved In humans, the presence or absence of dimples is a - Chegg
Question: In humans, the presence or absence of dimples is a trait controlled by a single gene What is the genotype of an individual a) dimpled b) DD who is heterozygous for dimples?
