Hand clasping dominant or recessive. Therefore the curly hair gene is dominant. More recent scientists believe that more than one gene may be involved. Hand clasping as a character Most people have a strong preference for clasping their hands in one way either with the left thumb on top L or the right thumb on top R.

People lacking hair in the middle segments of the fingers have two recessive versions of the gene. The first paper to look at arm folding Weiner 1932 clearly concludes that it has little or no genetic basis. For the redgreen colorblindness trait I am recessive because I.

Conversely an individual who has one dominant allele and one recessive allele is said to be heterozygous for that gene hetero- different or other. Feels strange and unnatural doesnt it. Curly hair is mostly determined by genes and less by environment.

In most cases the right handedness gene is dominant while left handedness gene is recessive.

If the trait is absent no hair on joint hand clasping with right thumb on top straight little finger the corresponding genotype is recessive. People with two recessive versions are non-rollers and can not learn. Although the data do not fit any straightforward recessive or dominant Mendelian model they are compatible with the type of model invoking fluctuating asymmetry which has been used to explain the inheritance of handedness hand-clasping and arm-folding.

Individuals who have two identical alleles for a given gene whether dominant or recessive are said to be homozygous for that gene homo- same. Hand clasping leftright locking thumbs - Clasp your hands together. In this case the dominant trait will be expressed and the individual will be phenotypically identical to an individual who possesses two dominant.

Hence to answer the question an X-linked dominant trait is a dominant characteristic located in the x chromosome while an X-linked recessive trait is one that is recessive. Which would perhaps be impressive if there was a large number of options.
