<u>Answer</u>:
1. C. Process one describes cloning and process two describe artificial selection
Through cloning a genetically identical individual is obtained from a single individual. Through artificial selection a hybrid between two individuals with desirable traits is obtained.
2. C. Polygenic
A trait that has a continuous variation has a polygenic inheritance pattern as it is controlled by multiple genes.
3. C. The BW mice would have black and white patches
Codominant genes will produce an individual with an intermediate phenotype as both alleles are simultaneously expressed in the heterozygote.
4. D. Polygenic
Polygenic inheritance occurs when two or more genes determine a trait that has a continuous variation. Each gene has a small effect, but all together have a cumulative effect. Examples of such patterns are height, sking color, eye color, weight etc.
Species is a type or kind of thing while ecomorph is a local variety of a species whose appearance is determined by it's ecological environment
Answer:
Red (1/4), Pink (1/2), white (1/4)
Explanation:
This question involves a single gene coding for flower colour in the snapdragon plants. The gene exhibits incomplete dominance, because the allele for red color (R) is incompletely dominant over the allele for white color (W), hence an intermediate phenotype is produced as pink color (RW).
The pink colored snapdragon plant is produced in the F1 generation. When these F1 offsprings are crossed i.e. RW (pink) × RW (pink), gametes with R and W alleles are produced by each F1 parent.
Using these gametes in a punnet square (see attached image), four possible offsprings with genotypes; RR, RW, RW and WW will be produced in the F2 generation.
RR offsprings (1/4)- Red flowered
RW offsprings (2/4 or 1/2)- Pink flowered
WW offsprings (1/4)- White flowered
The consumers that prey on krill would decrease in population resulting in a fall of that particular food web.
