What type of cross follows the simultaneous inheritance of two different traits?
The pattern of inheritance in which the expression of one gene masks the expression of another gene is known as . The phenomenon in which an individual expresses two different alleles of the same gene (as in blood type AB) is called . True or false: Most traits are influenced by one gene.
When two pea plants with round yellow seeds breed they produce many offspring all with round yellow seeds this population is considered?
When two pea plants with round, yellow seeds breed, they produce many offspring all with round, yellow seeds. The population is considered______. True-breeding.
Which of the following events can result in an offspring with unique heritable characteristics?
Which of the following events can result in an offspring with unique heritable characteristics? Meiosis, which occurs during sexual reproduction, allows for a great variety of possible gene combinations.
What explanation of inheritance suggests that hereditary traits are determined by discrete units that are transmitted from one generation to the next quizlet?
What explanation of inheritance suggests that hereditary traits are determined by discrete units that are transmitted from one generation to the next? Inheritance is the acquisition of traits by their transmission from offspring to parent.
What explanation of inheritance suggests that hereditary traits are determined by discrete units that are transmitted from one generation to the next?
Particulate inheritance is a pattern of inheritance discovered by Mendelian genetics theorists, such as William Bateson, Ronald Fisher or Gregor Mendel himself, showing that phenotypic traits can be passed from generation to generation through “discrete particles” known as genes, which can keep their ability to be …
What does it mean when pea plants are described as true breeding?
Mendel’s Crosses The result is highly inbred, or “true-breeding,” pea plants. These are plants that always produce offspring that look like the parent. By experimenting with true-breeding pea plants, Mendel avoided the appearance of unexpected traits in offspring that might occur if the plants were not true breeding.
Which of the following events can result in inheritable genetic variations in organism?
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism’s offspring).
What is the source of most heritable differences?
Most heritable differences are due to gene shuffling that occurs during the production of gametes.
Which term involved in genetic inheritance refers to a unit of heredity that determines characteristics of offspring?
Gene. A unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring. Allele. An allele is a variant form of a gene.
Which hypothesis of inheritance states that traits are inherited as discrete units from parent to offspring?
particulate hypothesis
The particulate hypothesis was offered by Gregor Mendel who discovered that traits are inherited in discrete units that we now know as genes. Instead of blending, the offspring inherits a version of a gene, called an allele, from each of the parents. Only one allele is expressed depending on a number of factors.
