...dominant traits

...common diseases

...and produce more in our gamets

...that would not have any impact in homozygosity

...but repare them in our gamets

The autosomal dominant inheritance

The X-linked recessive inheritance

The X-linked dominant inheritance

...we need to use as many mutations as possibe to explain the observed phenotype

...we always start deducing the most probable genotypes of the family members

...we always assume that people from outside the family carry a mutation in the same gene as the family

...variable expressivity, because the signs of the disease are too mild to be observed

...incomplete penetrance, because the signs of the disease are too mild to be observed

...genetic anticipation, because the signs of the disease are too mild to be observed

...germline mosaicism of both parents should be considered

...the probability of having a chimeric child in the next pregnancy would increase

...germline mosaicism of one of the parents should be considered

...are monogenic

...show clear inheritance patterns

...are common

...the environmental variability

...both the environmental and the genotypic variability

...the genotypic variability

...follow a normal distribution in the population

...are always caused by a unique mutation in one gene

...appear in people who exceed the threshold of genetic load for that particular characteristic
