Hippocrates, an ancient Greek philosopher, explained heredity following a "Pangenesis" hypothesis that was ultimately wrong. What was wrong about this idea? Because the ancient Greeks did not know about DNA It failed to explain why children resemble their parents It would allow for "acquired characteristics" such as baldness in an older parent to be passed to offspring. It would require that both parents were the same age

Biological determinism is the idea that most human characteristics, physical and mental, are determined at conception by hereditary factors passed from parent to offspring. However, this approach is considered limiting. Why is that?
Human communities around the world that are isolated geographically or culturally serve as an important resource for studying human genetics. Why would research on recessive alleles benefit from these communities?
Pedigree Analysis Is a Basic Method in Human Genetics Pedigree analysis permits all of the following except: a. an orderly presentation of family information b. the determination of whether a trait is genetic c. the determination of whether a trait is dominant or recessive d. an understanding of which gene is involved in a heritable disorder e. the determination of whether a trait is sex-linked or autosomal
It is a basic idea of human biology, taught in grade schools everywhere: Identical twins come from the same fertilized egg and share identical genetic profiles. But according to new research, though identical twins share very similar genes, identical they are not. The discovery opens a new understanding of why two people who hail from the same embryo can differ in phenotype (physical characteristics), as biologists refer to a person’s physical manifestation. The new findings appear in the March issue of The American Journal of Human Genetics, in a study conducted by scientists at the University of Alabama at Birmingham and universities in Sweden and the Netherlands. The scientists examined the genes of 10 pairs of monozygotic, or identical, twins, including 9 pairs in which one twin showed signs of dementia or Parkinson’s disease and the other did not. It has long been known that identical twins develop differences that result from the environment. And in recent years, it has also…
To determine whether radiation associated with the atomic bombings of Hiroshima and Nagasaki produced recessive germ-line mutations, scientists examined the sex ratio of the children of the survivors of the blasts. Can you explain why an increase in germ-line mutations might be expected to alter the sex ratio?
From your research, you discover that in this species of fish, the allele for black color is dominant to orange color. Based on this research, can you determine the genotype of a black fish just by looking at it? Why or why not? Yes, because the recessive allele must have been eliminated by the dominant one. Yes, because the phenotype always expresses all the alleles. No, because you do not know the DNA sequence. No, because it could be either homozygous dominant or heterozygous.
A scientist predicts that the kittens born with a congenital birth defect will be 25% based on the hypothesis that it is caused be a recessive gene in that breed of cat. After surveying several litters, he found that 44 out of 128 kittens had the defect. Is his hypothesis correct? Use Chi-Square to solve
Red hair in humans is inherited as a recessive trait. Bill and Sarah both have black hair. They marry and have four children, three of whom have red hair. Bill says it isn’t genetically possible for two black haired people to have 34 red-haired children, and he accuses Sarah of infidelity. Sarah says Bill is a homozygous dominant idiot and knows nothing about genetics. Who is correct and why?
Tay-Sachs disease is an autosomal recessive disease. Affected individuals do not survive to reproductive age. Why has Tay-Sachs persisted in humans?
If our DNA contains all the information about who we are, how can something that does not involve changing the gene sequence cause changes in phenotypes? Describe briefly how these changes happen.
Which of the following mutations cannot be inherited by a person's biological children? A mutation that the person inherited and is in all their cells A mutation that is in a gamete but none of the body cells A mutation that is in a body cell but none of the gametes
One of the first Mendelian traits identified in humans was a dominant condition known as brachydactyly. This gene causes an abnormal shortening of the fingers or toes (or both). At the time, some researchers thought that the dominant trait would spread until 75 percent of the population would be affected (because the phenotypic ratio of dominant to recessive is 3 : 1). Show that the reasoning was incorrect.
