Nov 30, 1998 · For every trait we have--eye color, skin color and so on--there is a gene or group of genes that controls the trait by producing first the message and then the protein. Sperm cells and eggs...

Traits are determined by an individual's genotype, the summation of the genes in our DNA. A gene is a portion of a chromosome. A chromosome is composed of DNA and contains the genetic material for an organism. Humans have twenty-three pairs of chromosomes. Twenty-two of the pairs are called autosomes. Autosomes are typically very similar in males a...
How are traits passed from one generation to the next? This happens when gametes unite. When an egg is fertilized by a sperm, for each chromosome pair, we receive one chromosomefrom our father and one from our mother. For a particular trait, we receive what is known as an allelefrom our father and one allele from our mother. An allele is a differen...
When alleles are expressed via simple dominant versus recessive traits, the specific alleles inherited determine how the phenotype is expressed. When an individual has two dominant alleles, the phenotype is the dominant trait. Likewise, when an individual has one dominant allele and one recessive allele, the phenotype is still the dominant trait. W...
A longer second toe and attached earlobes are often cited as examples of a "weird trait" that follows the two dominant/recessive alleles forms of one gene inheritance. Again, however, evidence suggests that both attached earlobe and longer second toe inheritance are quite complex.
“Attached Earlobe: The Myth.” Myths of Human Genetics, udel.edu/~mcdonald/mythearlobe.html.“Observable Human Characteristics.” Nutrition & the Epigenome, learn.genetics.utah.edu/content/basics/observable/.Traits are inherited characteristics from our parents that are expressed externally in our phenotype. Learn how traits are determined by genes, alleles, and chromosomes, and how they are inherited via simple or complex patterns.

Jan 30, 2023 · What carries the genetic information? Genetic information is all of the information stored in our DNA. DNA stands for “deoxyribonucleic acid.” The strands of DNA look like a twisted ladder, known as a double helix. Each step of this ladder is made up of two bases. There are four different bases: adenine (A) thymine (T) guanine (G) cytosine (C)

3 days ago · DNA, organic chemical of complex molecular structure found in all prokaryotic and eukaryotic cells. It codes genetic information for the transmission of inherited traits. The structure of DNA was described in 1953, leading to further understanding of DNA replication and hereditary control of cellular activities.
