What Is The Theory Of Natural? The theory of natural selection was explored by 19th-century naturalist Charles Darwin. Natural selection explains how genetic traits of a species may change over time. This may lead to speciation, the formation of a distinct new species. What is Darwin’s theory of natural? Darwinism is a theory of biological
Which Term Best Describes The Physical Expression Of A Trait? A phenotype is the physical appearance of a trait in an organism. A phenotype is an organism’s allele combination. How are traits expressed? Traits are inherited characteristics from our parents that are expressed externally in our phenotype. For any given trait, one gene variation (allele)
Which Of The Following Did Gregor Mendel Demonstrate With His Experiments Regarding The Discrete Hereditary Units That We Now Call Genes? —and, after analyzing his results, reached two of his most important conclusions: the Law of Segregation, which established that there are dominant and recessive traits passed on randomly from parents to offspring (and provided
What Determine Who We Are? Simply put, the many characteristics of humans exist on a spectrum, with genetic influences at one end and environmental impacts at the other. Some traits are entirely determined by our genes, like blood type, for example, while others are related to things in our environment. Do your genes determine your
Can Mutations Be Genetically Inherited? Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation. There are also nonhereditary mutations that occur in cells outside of the germ line, which are called somatic
What Determines A Baby’s Eye Color? Eye color is mostly genetic. One specific chromosome is largely responsible for determining your baby’s eye color. It carries two genes, one that determines the amount of melanin in the iris, and the other that controls the activity of the melanocytes. These genes work together to create your baby’s
Who Is Responsible For The Science Of Genetics? Genetics as a scientific discipline stemmed from the work of Gregor Mendel in the middle of the 19th century. Who discovered genetics using pea plants? The way in which traits are passed from one generation to the next-and sometimes skip generations-was first explained by Gregor Mendel. By
Why Is The Big 5 Model Of Personality Important? Why the Big Five Personality Traits Are Important The five-factor model not only helps people better understand how they compare to others and to put names to their characteristics. It’s also used to explore relationships between personality and many other life indicators. Why is personality traits
What Color Eyes Can Two Blue-eyed Parents Have? The laws of genetics state that eye color is inherited as follows: If both parents have blue eyes, the children will have blue eyes. The brown eye form of the eye color gene (or allele) is dominant, whereas the blue eye allele is recessive. What are the
What Structure Determines The Traits That Will Be Passed To Offspring? Genes carry the information that determines your traits (say: trates), which are features or characteristics that are passed on to you — or inherited — from your parents. Each cell in the human body contains about 25,000 to 35,000 genes. What determines the traits
