Apr 27, 2017 · Freckles, cleft chin and dimples are all examples of a dominant trait. Having almond-shaped eyes is a dominant trait whereas having round eyes is a feature controlled by recessive alleles. The trait of detached earlobes, as opposed to attached earlobes, is dominant.
- Widow’s Peak. Also known as mid-digital, hairline is a result of expression of the hairline gene. The gene contains 2 alleles: one for straight hairline, which is recessive and the other for widow’s peak, which is dominant.
- Bent Pinkie. If you are able to bend your 5 finger (pinkie) inwards towards the 4 finger, it means you have the dominant version of the gene responsible for the distal segment of the finger to bend.
- Crossing of Thumbs. This one in dominant and recessive traits list is common. When you are interlocking your fingers, observe your thumbs. If your left thumb crosses your right thumb, this means you have inherited one or two of the dominant allele.
- Earlobe Attachment. People have their ear lobes either attached to the sides of their heads or hanging free. Those with unattached earlobes have the unattached earlobe gene as the dominant gene and the attached earlobe as the recessive gene.
Mar 2, 2024 · A dominant character trait is a prominent and prevailing characteristic that defines an individual’s behavior or personality. For example, honesty, confidence, and kindness are all examples of dominant character traits.
Dominant traits are those traits which are expressed even in the presence of one copy of an allele for a particular trait in the gene. However, recessive traits are those that are expressed only when two copies of an allele are present in the gene. Let us understand this by a simple example.
Aug 3, 2023 · For example: If the dominant gene for brown eyes is “B” and the recessive gene is “b” for blue eyes, then the alleles for the dominant trait can be either “BB” or “Bb” while “bb” is for a recessive trait. A person will exhibit the dominant trait if they have a heterozygous set of alleles, i.e., BB or Bb.
Some alleles are dominant, meaning they ultimately determine the expression of a trait. Other alleles are recessive and are much less likely to be expressed. When a dominant allele is paired with a recessive allele, the dominant allele determines the characteristic.
