Question

Each summer, farmers compete to grow the largest pumpkin, which can weigh thousands of pounds. They go to great lengths to help their pumpkin grow, including using extra fertilizer, heaters on cool spring days, and enclosures to reduce herbivory by insects.

Suppose that botanists measure the variation in pumpkin weight due to genetic composition and environmental factors. They measure variation in standard deviations. Variation due to genetic composition equals 254 pounds, whereas the variation due to environmental factors equals 385 pounds.

From these data, calculate the phenotypic variance in pumpkin weight.

Answer 1

Variation is how much one is different from other .this may be genetic or may be influenced by environment.we have pumpkin which is also influenced by both genetic and environment.

I henetic variation is term used to I describe variation in DNA sequence in each of our genomes Arditvi There are multiple sources of genetic variation including mutation and genetic recombination. . some variation is result of dillerences in surroundings or what an individual does. This is called environmental variation. . In is also so there variation giren question affected by will be two a pumpkin environment type of Variation due to genetic - Vg = 254 Pound composition Variation due owe to to environmental - Ve 385 pour nn Yomer factors Variation due to phenotypic - Vp ² variance I we have a formulae V = Vg tve Vp = 254 + 385 = 639 pounds I hence I Phenotypic variance pumblin weight is to plan in 639 Pounds.
