Use the following words to complete this statement: phenotype, genotype, heterozygous, homozygous, traits, alleles, genes Chromosomes contain _______, which help to determine an organisms _____. Genes come in alternate forms called _____, and both parents may not have the same type of allele. The actual gene combination that an organisms receives from its parents is called its_____, while the trait that gets expressed as a result is referred to as its _____. If an offspring receives the same type of allele for a given gene from each parent, it is said to be _____for that trait. If the alleles differ, it is _____.
Which of the following statements about genotypes and phenotypes are true? (choose all correct answers) Group of answer choices 1. The genetic makeup of an organism constitutes its genotype. 2. An organism with two different alleles for a single trait is said to be homozygous for that trait. 3. Alleles are alternate forms of a gene. 4. The expressed physical traits of an organism are called its phenotype.
Which of the following are arguments against the expression "survival of the fittest"? Choose all that apply. (1, 2, 3, or 4 could be correct) "Fittest" implies absolute fitness, when relative fitness of one genotype compared to others is more important "Fittest" makes it sound like it is about physical fitness, when whether an individual reproduces may depend on other traits "Fittest" makes it sound like an individual will be fit in all environments, when in reality the same genotype may have different fitness in different environments Reproduction is more important than survival for transmitting genetic differences to progeny
In order for a trait to evolve via natural selection, which of the following must be true regarding the trait? (this is a multiple answer question - so select all correct) Group of answer choices There must be variation in the trait. The trait must make the organism survive longer than organisms with different traits. The trait must confer a reproductive advantage on the bearer of the trait. The trait must be heritable. The trait does not necessarily need to be passed down to offspring.

Which statement about genotype and phenotype is FALSE? Phenotype is determined solely by genotype. Genotype consists of hereditary information, whereas phenotype is the physical and biochemical expression of genotype, influenced by the environment. The same genotype may produce different phenotypes. The same phenotype may result from different genotypes.
Which of the following statements best describe the equation P = G + E + (G X E)?* a. The phenotype is the sum of the genotype and the environment. b. The phenotype of an organism is determined by its genetic traits. c. The phenotype is the total characteristics displayed by an organism that results from the expression of the genes as well as the influence of environmental factors. d. The phenotype is the observable and measurable characteristics of an organism as a result of the interaction of the genes of the organism, environmental factors, and random variation.
