Genetic Variation
Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.
Quantitative Genetics
Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
- If red flowers are incomplete dominant to white flowers, the
phenotype of a flower that is heterozygous would be- red
- white
- pink
- purple
- yellow
Allele responsible for red phenotype is 'R'.
Allele responsible for white flower is 'r'.
So, genotype of heterozygous is 'Rr'
Step by step
Solved in 2 steps
- Let P = purple flowers and p = white, and T = tall plants and t = dwarf. What are the genotypes of the gametes that are produced by a plant that is heterozygous for both traits? hint* This is a dihybrid self cross of an F1 heterozygous generation. O Tt, TT, tt, Pp, PP, and pp P, p, T, and t PT, Pt, pT, and pt PT and ptA plant with genotype AAbbccDDEE is crossed with one that is aaBBCCddee. F1 individuals are selfed. What isthe probability of getting a F2 plant whose genotype is exactly the same as the genotype of one of the originalparents?A pea plant that is (RrYy) is allowed to self-fertilize. Round seed(R) is dominant to wrinkled (r), and yellow seed (Y) is dominant togreen (y). What is the probability of producing the following groupof five seeds: two round, yellow; one round, green; one wrinkled,yellow; and one wrinkled, green?
- In a certain species of flowering plants with a diploidgenome, four enzymes are involved in the generationof flower color. The genes encoding these four enzymes are on different chromosomes. The biochemical pathway involved is as follows; the figure showsthat either of two different enzymes is sufficient toconvert a blue pigment into a purple pigment.→ white → green → blue → purpleA true-breeding green-flowered plant is mated with atrue-breeding blue-flowered plant. All of the plants inthe resultant F1 generation have purple flowers. F1plants are allowed to self-fertilize, yielding an F2 generation. Show genotypes for P, F1, and F2 plants, andindicate which genes specify which biochemicalsteps. Determine the fraction of F2 plants with thefollowing phenotypes: white flowers, green flowers,blue flowers, and purple flowers. Assume the greenflowered parent is mutant in only a single step ofthe pathwayA male plant with genotype AaBBCcDdee was crossed with one heterozygous for all thegenes. (a) what is the probability of getting a pollen with ABcDe genes? (b) of producing anovum with three dominant and two recessive genes? (c) of getting a progeny with samephenotype as the female parent? (d) of progeny with exactly same genotype as the femaleparent? (e) If instead of the above male, the cross was with one heterozygous for all thegenes, what proportion of the offspring will have three dominant phenotypic traits. (f) willbe genotypically like the parents?More Crosses with Pea Plants: The Principle of Independent Assortment Consider the following cross: P1: AABBCCDDEE aabbccddee F1: AaBbCcDdEe (self-cross to get F2) What is the chance of getting an AaBBccDdee individual in the F2 generation?
- In Figure 3-21, what would be the leaf types of progenyof the apical (top) flower?Round seed is dominant over wrinkled. Yellow cotyledon is dominant overgreen. Full pod is dominant over constricted. The genes for these traits arefound on separate chromosomes. If a trihybrid plant is self-fertilized, whatproportion of the progeny will have round seeds in constricted pods?Express answer in fraction form.Suppose you have an AAaa tetraploid plant and it undergoes self-fertilization. At least two copies of thedominant allele A are needed to obtain the dominantphenotype. At what frequency will progeny with thedominant phenotype appear?
- Suppose you have an AAaa tetraploid plant and it undergo self- fertilization. At least two copies of the dominant allele A are needed to obtain the dominant phenotype. At what frequency will progeny with the dominant phenotype appear?Y = yellow, y = green; R = round seed, r = wrinkled seed Dihybrid cross: If you mate YyRr x YyRr then what proportion of offspring will be green and wrinkled? 6/16 3/16 O 1/16 O 9/16. In nature, the plant Plectritis congesta is dimorphic forfruit shape; that is, individual plants bear either winglessor winged fruits, as shown in the illustration.Wingless fruit Winged fruitPlants were collected from nature before floweringand were crossed or selfed with the following results:Number of progenyPollination Winged WinglessWinged (selfed) 91 1*Winged (selfed) 90 30Wingless (selfed) 4* 80Winged × wingless 161 0Winged × wingless 29 31Winged × wingless 46 0Winged × winged 44 0*Phenotype probably has a nongenetic explanation.Interpret these results, and derive the mode ofinheritance of these fruit-shaped phenotypes.
