Two true-breeding strains of corn with the genotypes CC and cc are crossed, where C = crunchy phenotype is dominant to c = soft

phenotype. The resulting F1 corn are crossed, and the ratio of crunchy to soft phenotypes in the F2 generation is 3:1. This is an example of:
A. non-disjunction.
B. a di-hybrid cross.
C. a mono-hybrid cross.
D. a test cross.
E. complementation.

Answer:

The correct answer will be option-C

Explanation:

A mono-hybrid cross is a cross which is performed to study the pattern of inheritance involving or studying a single trait at a time.

In the given case, the trait studied is the texture of corn seed with two versions that are crunchy and soft phenotypes. The crosses made between them showed 3:1 ratio of crunchy to soft phenotypes in F₂ generation.

Since 3:1 ratio in F₂ generation is obtained in the monohybrid cross therefore, Option-C is the correct answer.

suppose that individuals in a population of beetles differ in the extent of a dark pigment in their coloration. dark-colored bee
sesenic [268]

The coloration of the beetles most likely remains constant, despite differential predation, when it is strictly due to ENVIRONMENTAL factors. Phenotypic traits can be influenced by genes or the environment.

The expression of a given characteristic (i.e., a phenotypic trait) in an individual may be associated with genetic and environmental factors, as well as with the interaction between genetic and environmental factors.

Different types of environmental inputs (e.g., diet, temperature range, oxygen, humidity, light, etc) can influence a given phenotype.

A heritability value near zero (0) indicates that almost all of the phenotypic variability for a given trait is caused by environmental factors.
