Which of the following terms is the most broad?
phenotype
character
trait
Answer and Explanation:
Character
Character is generally defined as any type of features of an organism such as an organism's genetic make up (DNA or RNA viruses) or flying ability of a bird (flight or flightless) etc. It is a broader form of defining the features. It will only tell whether the bird can fly or not. It do not tell the wing color or presence or absence of wing.
Trait is a distinct or specific character or feature of an organism. Example: Size, color etc.,
Phenotype is defined as "any observable traits" which results from the genotype of an organism. For example a bird's wing color or height of an animal.
Which of the following terms is the most broad? phenotype character trait
You determine broad-sense heritability for quantitative trait and find a very low H^2 value. This could be caused by: Question options: a). Having a huge number of loci controlling the trait, with variants in each locus having very little (quantitative) contribution to that trait. b). Genotypic variation having a major effect on gene-gene interactions c). Having a significant level of narrow-sense heritability, which is not represented within the broad-sense Heritability d) The increased difficulty in detecting broad-sense heritability for continuous...
What is the relationship between character (trait) displacement and the competitive exclusion principle? A. Character (trait) displacement refers to predator-prey interactions, while the competitive exclusion principle refers to competition between species on the same trophic level. B. Rationale for character (trait) displacement stems from the competitive exclusion principle. Species exhibit evolutionary change leading to different ecological niches, as a result of competition. C. The competitive exclusion principle details that productivity limits the number of trophic levels in a community. Similarly,...
Which of the following best describes character displacement? o A Any trait associated with resource partitioning B Any evolutionary change of a trait that allows a species to utilize more resources o c Evolutionary change of a trait that allows similar species to utilize different resources when living together to minimize competition O D All of the above
All of the following regarding sickle cell anemia phenotype is true, except: a. Sickle cell trait in HbB/HbS heterozygotes gives them resistance to malaria b. Properties of oxyhemoglobin are severely affected by HbS substitution c. Both alleles in hemoglobin beta-chain (HbB) gene are mutated in a full-blown condition d. Solubility of deoxyhemoglobin is decreased
Use a Punnett square to predict offspring outcome for the following parent crosses Trait we are tracking is plant height in which T = Tall Trait and t = Short Trait 3. Questions to Answer: 1.Given what you know about trait expression which trait is Dominant & which is Recessive in this example? 2. For each Genotype indicate what the Phenotype would be: T T = ______, T t = _________, t t = ___________ Assuming one parent had...
Which of the following is incorrectly matched? Group of answer choices physical expression of a trait - phenotype allele whose expression can be masked by an alternate allele - recessive allele that masks expression of alternate allele - dominant identical alleles - homologous
Red-green color blindness is a sex-linked trait, with the normal vision phenotype being dominant (C) and the color blind (c) phenotype being recessive. If you are male and your father is color blind, what is the chance (expressed as a percentage) that you will inherit his trait for color blindness? What if your mother is a carrier for color blindness (but your father is not color blind), what is the chance of you being color blind? Make sure...
please answer all of them 9. Which of the following genetic terms describes an observable trait of an individual? A. Heterozygous B. Genotype C. Phenotype D. Homozygous 10. Mutations during which of the following processes in animals will affect offspring of succeeding generations? A. Meiosis B. Mitosis C. Translation D. Transcription 11. Which of the following will happen if mRNA fails to be translated? A. The cell's nucleus will produce more chromatin. B. Ribosomes will not be able to create...
2: Explain why the most common phenotype is usually an intermediate phenotype in most wild populations.
When graphing a distribution of phenotypes for a continuous trait, a broad curve implies Question 6 options: little variation in the phenotypes. a large standard deviation. a small variance. a large correlation coefficient. zero regression line slope.
