- true for false? 1a) In Drosophila flies, there are wing shapes such as curly, apterous, miniature and others. These would be considered continuous traits (as opposed to discontinuous traits). 1b) The reason we assess the narrow sense heritability is because there are hidden genetic components that are simply too difficult to include in the calculation of VG 1c) You can figure out the heritability of a trait if you compare the variation of the trait in a clonal population of organisms to a wild type (heterogeneous) population.Give only typing answer with explanation and conclusion A quantitative trait with mean 5 and std 0.24. You calculate VG = 0. Explain what VG = 0 means in terms of heritability. How does this trait have phenotypic variation if VG = 0?The broad-sense heritability of a trait is estimated at 0.6. If the total phenotypic variance is estimated at 30.0, what is the genetic variance? 12 18 36 5 9

Phenotypes for quantitative traits are determined by multiple alleles at multiple loci. ii. Phenotypes for quantitative traits can be influenced during development by environmental factors. iii. Height exemplifies a quantitative trait in humans.iv. What appears to be a classic Mendelian trait could in fact be a quantitative trait but with one locus contributing a very, very, very large effect and many other loci contributing very, very, very small effects. v. Quantitative trait loci must occur on the same chromosome. Question 3 options: A) Statements i and ii convey inaccurate information. B) Statement v conveys inaccurate information.

State the possible phenotypes for the children and the likelihood of having those phenotypes according to the Punnett Square. Also state the likelihood of having all the genotypes according to the Punnett Square. Questions 8 through the end of the sheet have their own instructions. The genotypes, phenotypes, and methods of inheritance for these human traits are real. Mother: EE Father: ee E = moist earwax e = dry earwaxtrue or false (please do them ALL) 1. Heritability estimates is a portion of phenotypic variation contributed by heredity. Traits in pigs such as ovulation rate and number of piglets produced per year are highly heritable traits. 2. The formula for computing crude protein is equal to the amount of nitrogen multiplied by 6.25. This is based on the fact that ALL protein materials contain 16% nitrogen. 3. Essentiality of a nutrient depends on the factors such as species, age, health, metabolism. 4.The deficiency symptoms of Selenium may be associated or similar with vitamin E deficiency. 5. Lipids have similar elemental components as carbohydrates but contains more energy because that ratio is greater for oxygen

Mean(mm). Variance (mm) P1 short 40.47. 3.12 P2 long. 93.75. 3.87 F1(P1×P2). 63.90. 4.74 F2(F1×F2). 68.72. 47.70I. OBJECTIVES At the end of the activity, the students are able to: A observe the separation and independent assortment of alleles: B. demonstrate the inheritance of dominant and recessive traits, codominance. and incomplete dominance: and C. construct a model of a dragon based on the characteristics inherited from the parent dragons. II. MATERIALS Writing materials 2 Five-peso coins 2 One-peso coins 2 Twenty-peso coins Ill. PROCEDURE I. In this activity. you and a partner will work together to produce o baby dragon from the random mixing of genetic traits. Each student will be a surrogate dragon parent. Surrogate dragon parent partners must be of the opposite sex. therefore the female has X/X chromosomes white the male has X/Y chromosomes. You can ask your parent. sibling. or relative to work with you Or you Can work with your Classmate. 2. Each partner must have three different coins -- one of each color of autosome (green and yellow autosomes). and one sex chromosome coin_ You can…The leaf width of a particular plant has an environmental variance of 2.3 cm, an epistatic variance of4.8 cm, a dominance variance of 1.6 cm, and an additive variance of 3.8 cm.

A plant producing tomatoes with an average of 7 grams is used in one self-fertilization cross to produce a line of smaller tomatoes, and a plant producing tomatoes of 21 grams is used in a second cross to produce larger tomatoes. What is the selection differential (S) for the fruit weight in each cross? If narrow-sense heritability (h2) for this trait is 0.7, what are the expected responses to selection (R) for fruit weight in the crosses?Multiple choices: Question: Handedness (whether you are right or left-handed) shows a 79% concordance in monozygotic twins and a 77% concordance in dizygotic twins. Using this information, do you expect handedness to have a large genetic influence? a. No, although the concordance numbers are high, they are similar between MZ and DZ twins b. No, concordance is not 100%
