Answer:
Random chance mutations led to the webbed feet trait in ancestral land birds, conferring them an adaptive advantage. Birds that inherited the beneficial random mutations associated with the webbed feet trait had more chances to survive and reproduce, passing this trait to the next generations.
Explanation:
Mutations are ramdom changes in the nucleotide sequence of the genome of a particular organism. In general, mutations are deleterious, but mutations may occasionally be beneficial in certain environments. A beneficial mutation must be associated with one or more phenotypic traits capable of conferring an adaptive advantage in a certain environment, thereby the individuals carrying the mutation have more chances to reproduce and survive. In this case, one or more beneficial mutations associated with the webbed feet trait passed to the next generations, increasing their frequency in the population.
The chance of getting a red flower if two pink flowered plants are crossed is 25% or ¼.
<h3>WHAT IS INCOMPLETE DOMINANCE?</h3>
Incomplete dominance is a type of inheritance in which two alleles of a gene are neither dominant or recessive, hence, a intermediate phenotype is produced.
According to this question, in snapdragons, petal color is inherited through incomplete dominance with the possible colors being red, white, and pink.
If two pink flowered plants are crossed i.e. Pp × Pp, the genotype of the offsprings that will be produced as follows:
- PP (1) - red flower
- Pp (2) - pink flower
- pp (1) - white flower
Therefore, the chance of getting a red flower if two pink flowered plants are crossed is 25% or ¼.
