In a certain population of birds, 16 percent of the population have grey feathers and 84 percent have red feathers. If grey feathers is a recessive trait, what percentage of the population is heterozygous for this trait?
a. 20%
b. 32%
c. 48%
d. 64%

If grey feathers is a recessive trait, then 72.8% of the population is heterozygous for this trait.

Explanation:

The concept used here is of Hardy Weinberg principle, +2pq =1

The homozygous dominant genotypeis represented as = 84

Red = dominant

The homozygous recessive genotype trait is represented as = 16

grey = recessive

2pq = heterozygous individual

Thus for dominant homozygous the alleles are given as

p=

  = 9.1

q =

  = 4

for heterozygous individual 2pq

2 x 9.1 x 4

= 72.8

72.8% population is heterozygous for the trait.

corona the outer atmosphere of the sun, temp. may reach 2,000,000 c

chromosphere middle layer of the sun's atmosphere

photosphere visible surface of the sun

convection zone layer of the sun which energy travels by convection from the radiative zone to the photosphere

radiative zone layer of the sun which energy is transferred away from the core by radiation

core very dense center of the sun

nuclear fusion process by which tow or more low-mass atomic nuclei fuse to form another, heavier nucleus.

radiation when energy is transferred as electromagnetic waves

convection the process in which heat is transferred by the circulation or movement of matter

differential rotation the way the sun rotates, rotating faster at its equator than at higher latitudes

sunspots dark areas that form on the surface of the sun

solar flare an explosive release of energy that can extend outward

prominences huge loops of cool gas that extend outward from the photosphere

the correct answer is (
