The main factor that influences a person’s height is their genetic makeup. However, many other factors can influence height during development, including nutrition, hormones, activity levels, and medical conditions. Scientists believe that genetic makeup, or DNA, is responsible for about 80% of a person’s height.

Heredity is the biological process responsible for passing on physical traits from one generation to another. Heredity will determine a person’s hair color and height. And due to heredity, some people are more susceptible to diseases and disorders like cancer, alcoholism, and depression.

Heredity is the passing of traits from parent to offspring.

Heredity is defined as the characteristics we get genetically from our parents and our relatives before them. An example of heredity is the likelihood that you will have blue eyes. An example of heredity is your possibility of having breast cancer based on family history.

An inherited trait is one that is genetically determined. Inherited traits are passed from parent to offspring according to the rules of Mendelian genetics. Most traits are not strictly determined by genes, but rather are influenced by both genes and environment.

No organism has all dominant or all recessive genes. An organism may be pure in certain traits and hybrid others. Remember, that a dominant trait in one kind of organism may be a recessive trait in another organism. 1.

Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism.

Some studies have even found that newborns tend to resemble their mothers more than their fathers. In a 1999 study published in Evolution & Human Behavior, French and Serge Brédart of the University of Liège in Belgium set out to replicate the paternal-resemblance finding and were unable to do so.

Y-chromosomes have fewer genes than X-chromosomes and some of them are responsible for the development of male genitals. This is why a boy is more likely to look like his mother.

However, several studies since then have shown that most infants resemble both parents equally. One study even suggests that in the first three days of life, the baby looks more like the mother—but she will tend to say the opposite, emphasizing the child’s resemblance to the father.

“They also recognize their parents’ voices from the moment they are born. If dad sings to the baby while baby is still in the womb, baby will know the song, calm and look to dad.” The family that sings together, stays together.

As long as their needs are being met, most babies younger than 6 months adjust easily to other people. Babies learn that when they can’t see mom or dad, that means they’ve gone away. They don’t understand the concept of time, so they don’t know mom will come back, and can become upset by her absence.

Dads experience hormonal changes, too Pregnancy, childbirth and breastfeeding all cause hormonal changes in mothers. However, researchers have found that men also undergo hormonal changes when they become fathers. Contact with the mother and children seem to induce the hormonal changes in dads, the researchers said.
