Question

which of the following is/are false? assume a diploid organism. please select all applicable options. marks will be removed for incorrect selection(s). question 2answer a. four or more different alleles may be present for any given gene in an individual. b. the activity of one gene, in some circumstances, can affect the activity of a different gene. c. three or more different alleles may be present for a given gene in a population. d. co-dominance of alleles involves one gene masking the activity of another gene.

Answer 1

Option c. is false because three or more different alleles may be present for a given gene in a population, not in an individual. Option d. is false because co-dominance involves both alleles being expressed without one masking the other.

Step-by-step explanation:

Multiple alleles refer to the existence of more than two alleles for a given gene in a population.

In a diploid organism, an individual can only have two alleles for a given gene.

However, at the population level, multiple alleles can be present.

Therefore, option c. is false as it states that three or more different alleles may be present for a given gene in an individual.

Co-dominance is a form of inheritance where both alleles for a gene are expressed equally in the heterozygous condition.

This means that both alleles are independently expressed without one allele masking the other.

Therefore, option d. is false as it states that co-dominance involves one gene masking the activity of another gene.
