ambition

What does a girl inherit from her father?
Girls get two X chromosomes, one from Mom and one from Dad. This means that your daughter will inherit
X-linked genes
from her father as well as her mother. When your daughter inevitably ends up with his X chromosome, does that mean she’ll inherit all of his X-linked genes and traits? Genes, yes.

.

Heritability is estimated by comparing individual phenotypic variation among related individuals in a population, by
examining the association between individual phenotype and genotype data
, or even by modeling summary-level data from genome-wide association studies (GWAS).
What percent of IQ is genetic?
These studies suggest that genetic factors underlie about
50 percent
of the difference in intelligence among individuals.
What does a heritability of 1 mean?
Heritability measures how important genetics is to a trait. A high heritability, close to 1, indicates
that genetics explain a lot of the variation in a trait between different people
; a low heritability, near zero, indicates that most of the variation is not genetic.
