lilavasa [31]

Answer:

- Complete dominance: one allele masks the expression of the other gene variant or the phenotype is caused by the absence of gene function when both alleles are recessive.

- Incomplete dominance (codominance): both alleles are expressed and contribute to the phenotype

Explanation:

Complete dominance is a type of dominance by which one allele (dominant allele) completely masks the effects of another allele (recessive allele) in heterozygous individuals (i.e., individuals carrying two different gene variants or alleles). On the other hand, codominance refers to a type of incomplete dominance where both alleles in the genotype are observed in the phenotype. Complete dominance is caused when the recessive allele is not expressed, while if both alleles are expressed it is called incomplete dominance.

IrinaVladis [17]

For accuracy and reliability of any experiment, a number of observations must be as large as possible. It reduces the effect of any observation or any event which might have happened by chance or error.

Thus, finches were better to record observations as they were available in large number as compared to the tortoise.

In addition, the life cycle of birds is smaller as compared to the tortoise which enabled the scientists to observe more generations.

Lastly, the birds were easy to capture and track as compared to the tortoise. Tortoise being an amphibian could live on land as well as in water which made it difficult to track them.
