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.

- In peas, yellow seed (Y) is dominant over green seed (y). Inthe F2 generation of a monohybrid cross that begins when adominant homozygote is crossed with a recessive homozygote,you would expecta. three plants with yellow seeds to every plant with greenseeds.b. plants with one yellow seed for every green seed.c. only plants with the genotype Yy.d. only plants that produce yellow seeds.e. Both c and d are correct.In the example below, crossing you left thumb over your right thumb is dominant T to crossing your right over left recessive t. Identify the genotype of the individual shown below: OShutterstock / robynleig O A. homozygous dominant (TT) O B. heterozygous dominant (Tt) or homozygous dominant (TT) OC. homozygous recessive (tt) O D. Cannot be determined from information providedIn pea plants, round peas (R) are dominant to wrinkled peas (r). You do a test cross between a pea plant with wrinkled peas (genotype rr) and a plant of unknown genotype that has round peas. Result: 4 plants with round peas. What is the unknown parent? Use Punnett square on homework to help answer the question. O a. Homozygous dominant O b. Heterozygous O c. Homozygous recessive O d.
- If a mouse has a dominant phenotype (P_), how would you determine if it is homozygous (PP) or heterozygous (Pp)? Select one: O a. O b. O c. O d. O e. cross it to a mouse with the dominant trait but a similarly unknown genotype. cross it to a mouse with the recessive trait. cross it to a homozygous dominant mouse. it cannot be determined. cross it to a heterozygous dominant mouse. OIn pea plants, the allele for round seeds (R) is dominant and the allele for wrinkled seeds (r) is recessive. Under what conditions would we observe wrinkled seeds in a pea plant?A. When the plant has a genotype RRB. When the plant inherits a dominant allele from both parentsC. When the plant inherits a recessive allele from both parentsD. When a plant has a heterozygous allelic pair of the gene for seed shapeChoose the statement that is incorrect.a. A son can inherit a recessive allele on anX chromosome from either parent.b. An individual may inherit three or more of eachtype of chromosome characteristic of the species, acondition called polyploidy.c. A female child inherits one X chromosome from hermother and one from her father.d. Pedigree analysis can be used to determine a futurechild’s chance of being born with achondroplasia
- Manx cats have no tail. This is caused by a dominantmutation M, which is embryo lethal when homozygous. An unlinked gene B controls the color of the fur onthe cat's tail. The dominant B allele produces black fur on tails, while the recessive allele b produceswhite fur on tails. A Manx cat that is B/B is crossed to a white-tailed cat. Half of the F1 progeny hadthe Manx phenotype and the other half had normal, black tails.The F1 cats with the Manx phenotype were crossed to each other, producing F2 cats. What is the ratioof the following phenotypes in the F2Figure 8.9 In pea plants, round peas (R) are dominant to wrinkled peas (r). You do a test cross between a pea plant with wrinkled peas (genotype rr) and a plant of unknown genotype that has round peas. You end up with three plants, all which have round peas. From this data, can you tell if the parent plant is homozygous dominant or heterozygous?In a test cross, peas of an unknown genotype are crossed with peas of a known genotype. In this example, smooth peas are the unknown and wrinkled peas are the known (rr). If half of the offspring from that cross are smooth and half are wrinkled, what is the genotype of the unknown plant? O a. Homozygous dominant: RR O b. Homozygous recessive: rr Oc. Incomplete dominance d. Heterozygous dominant: Rr CLEAR MY CHOICE
