Hair length varies dramatically on different body sites and also varies between individuals. Thus, hair length is a quantitative trait, suggesting inherited differences.
But yeah, short answer is that genetics do determine the maximum length your hair can grow, but things like your health and the way you care for your hair can greatly affect how much actually grows versus how much breaks/gets cut off.
There are two factors that determine your hair length. Genetics and maintenance. Genetics determine just how long your hair can grow to at its maximum, assuming you are also doing everything you can to maximize its growth.
To understand how the long-haired phenotype can appear in the offspring of two short-haired dogs, we need to look at the genetic principles of inheritance. In this case, short hair (L) is a dominant trait, while long hair (l) is a recessive trait.
The ability to grow very long hair may be a result of sexual selection since long and healthy hair is a sign of fertility. An evolutionary biology explanation for this attraction is that hair length and quality may act as a cue to youth and health, signifying a woman's reproductive potential.
Short hair is due to a dominant gene L and long ahir to its recessive allele 1 (in rabbit). A cross between a short-haired female and a long haired male produces a litter of 1 long haired and 7 short haired bunnies.
The best predictor of a child's height is their parents' height or, more specifically, the mid-parental height. The mid-parental height is calculated by adding the mother's and father's height, adding 13 cm (5 inches) for boys or subtracting 13 cm (5 inches) for girls, and then finally dividing by 2.
While a baby inherits half of their eye color genetics from one parent and half from the other parent, the way that the multiple genes interact also plays a role in determining eye color.
Does pubic hair cease growing once it's reached a certain length? All hair grows at a contstant rate, but eventually falls out. With body hair, which typically does not grow as long as head hair, the rate at which it falls out is greater. This results in hair that appears to reach a certain length then stops growing.
Longer hair in women seems to be considered attractive regardless of facial attractiveness (Meskó & Bereczkei, 2004) . On the other hand, baldness tends to be perceived as less attractive in Western cultures and bald men have fewer lifetime sexual partners (Sinclair et al., 2013). ...
Hair length varies dramatically on different body sites and also varies between individuals. Thus, hair length is a quantitative trait, suggesting inherited differences.
How long your hair is capable of growing is determined by the length of your anagen phase and how fast your hair grows (eg half an inch a month or one inch a month). The anagen phase is the growing phase of hair before and sheds. The anagen phase on average varies from as short as 2 years to as long as 6 years.
Although colors and patterns are determined by a combination of genes, a single gene, FGF5 (fibroblast growth factor 5), determines hair length. Short hair is the dominant code in the gene; four mutations of the gene produce long coats.
According to studies, mitochondrial DNA is inherited solely from the mother.
Though it's probable that your real height is close to your predicted height, this isn't always the case. It's entirely possible for two short parents to have a tall child, and vice versa. It's just more likely that the child of short people will end up vertically challenged.
Fathers will always pass their X chromosome to their daughters and their Y chromosome to their sons. Because females have two X chromosomes, carriers have a second non-pathogenic (or 'wild type') copy of the gene.
A striking characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons; fathers only pass X chromosomes to their daughters and Y chromosomes to their sons.
Facial features
Babies often look like their fathers at birth, a phenomenon thought to encourage bonding between dad and child. This resemblance isn't just random; many facial features like jawline and nose shape can strongly mirror dad's genetics.
Long hair is a recessive trait, which means that a dog must inherit a long-hair gene from each parent in order to have long hair.
Although it is a widely accepted opinion that common baldness is an autosomal dominant phenotype in men and an autosomal recessive phenotype in women, or indeed that baldness is genetically influenced, it is based on surprisingly little empirical data.
