Is the current rate of species loss 10 times the typical rate of extinction?
Anika [276]
The natural rate of extinction as assumed by science is about 5 species per year. Currently scientists estimate we are losing species at 1000-10000 times that rate, with multiple species disappearing every day. A note on this idea is that the average extinction rate gives an unrealistic depiction of nature when we consider the catastrophic extinction events that ended the dinosaurs and shaped the ice age.

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.
