One example of a sexually influenced trait in humans would be haemophilia. The gene responsible for haemophilia is located on the X chromosome, and if a man receives a gene from his mother (men's X chromosomes always come from their mother) that is positive for this trait, he will exhibit haemophilia. Women must have two X chromosomes that are positive for haemophilia in order to exhibit the trait, because it is a recessive gene.
false
It depends on the trait. Some traits exhibit simple Mendelian heredity, being governed by only one gene. However, many traits are governed by more than one gene, which is called polygenic inheritance.
While taking a bath is an instinctive action by some species (notably cats and humans), it is not a trait that they exhibit as part of their biology.
Yes, calmness can be considered a personality trait. It is characterized by a state of composure, tranquility, and the ability to remain composed and relaxed even in stressful situations. People with a calm personality trait tend to handle stressful situations with poise and exhibit a sense of inner peace.

If the the trait is controlled by only one allele and the allele is completely dominant then once inherited the offspring with exhibit that phenotype

Spontaneous mutation can affect a gene. The Organism can learn - though some would not call anything learned "a trait"
false
False. if that was the case there can be no development.
The term dominant is a misnomer here as the trait is not dominant or the number of women with the trait would be much higher. Pattern baldness is a sex-linked trait. Male pattern baldness alleles are present on the X chromosome which means that only one copy of the allele is required for a male to exhibit the trait (the y chromosome, being much smaller, doesn't have the gene locus for this trait). Females must have 2 alleles for the characteristic in order to exhibit the the trait.
