Question

Is straight thumb is dominant or recessive?

Answer 1

Dominant trait:

1. All the traits of our body are controlled by genes and environmental effects.
2. For a particular trait, there is a gene responsible for that.
3. There can be two or multiple alleles of that gene.
4. An allele can be dominant on the other one.
5. When a dominant trait can be seen in an individual, the dominant allele is responsible for that.
6. A dominant allele can show its effect even in heterozygous conditions.
7. A straight thumb is a dominant trait because it is controlled by a dominant allele.
