Use the Punnett square to predict the genotype for the parent organism whose genotype is unknown and
Katyanochek1 [597]

Answer: The genotype for the parent organism whose genotype is unknown is Ff.

Explanation: Let (F) represent the allele for purple which is dominant over (f) and (f) represent the allele for white.

The parent organism whose genotype is unknown is heterozygous for purple colour (Ff).

A cross between Ff and ff will produce four offsprings: two of which are Ff (heterozygous for purple colour) and two are ff (white).

Ff x ff = Ff, Ff, ff and ff.

Since (F) is dominant over (f), (Ff) will manifest as purple while (ff) will manifest as white. Therefore, half of the offsprings are purple while the other half are white.

Hybridization is the process through which two species can mate with each other and produce fertile offspring thus creating a new species.

This is not happening with the two palm species on the island. This may be due to prezygotic barriers that prevent these two species from mating and producing a zygote (fertilized egg cell). In essence these barriers prevent any gene flow between the two species.
