Gene A has two alleles (A1 and A2). A1A1 homozygotes are twice as likely to survive from birth to reproductive age as heterozygo

Usimov [2.4K]

Answer:

The correct answer is C: 0.60 A1 and 0.40 A2 will be the allele frequencies in those progeny when they reach reproductive age

Explanation:

Genotype A1A1  A1A2 A2A2 

Relative aptitude, w 1 0.5 0.5

Number of individuals 40 40 40

Initial allelic frequency p0= (40+20)/120=0.5 q0= (40+20)/120=0.5

Zygote frequency p2= 0.25 2pq=0.25 q2=0.625

Relative contribution 0.25x1=0.25 0.5x0.5=0.25 0.25x0.5=0.125

of each genotype

Average aptitude W W= 0.025 + 0.25 + 0.125 = 0.625

Population AA= 0.25/0.625 AB=0.25/0.625 BB=0.125/0.625

Genotype frequency AA= 0.4 AB=0.4 BB=0.2

New Allelic frequency p1=0.4+(0.4/2)=0.6 q1=0.2+(0.4/2)=0.4

Total number of individuals: 120

Initial allelic frequency:

(number of homozygote individuals + half number of

heterozygote individuals) / Total number of individuals

Relative contribution of each genotype:

Zygote frequency x Relative aptitude

Average aptitude W: It is the sum of relative contribution of each genotype to the next generation.

wA1A1 x p2 + WA1A2 x 2 x p x q + WA2A2 x q2

Population Genotype frequency:

Relative contribution of each genotype / Average aptitude

Allelic frequency:

Homozygote population genotype frequency + half

heterozygote population genotype frequency

The following image shows a pencil submerged in a glass of water. A friend thinks that the pencil is broken. How would you expla

dezoksy [38]

Correct answer: A). Light slows down as it moves from the air in to the water, resulting in refraction, or a bending of light.

This is because as light travels through one media it travels in a straight line, however, when it travels from one media to another media it bends, light path bends because of the phenomenon of refraction of light.

The refraction takes place only at the boundary, as the light continues to cross the boundary, it travels in a straight line.

So, as the portion of the pencil is submerged in water, the light will travel from water to air.

Hence it appears to be broken because of refraction of light. So, the correct answer would be option A.

The Coriolis Effect is caused by Earth’s uneven distribution of heat AND ________________.

SCORPION-xisa [38]

The rotation of the earth

The Coriolis Effect is caused by Earth’s uneven distribution of heat AND the rotation of the earth

Explanation:

Due to the spherical nature of the earth, when it spins, around its axis, different latitudes spin at different rates. The nearer to the pole you get the slower the earth’s spins (approx 0.00008 kilometers/hr), while this spin is fastest at the equator ( approx1,600 kilometers/hr). Due to this differential spin, ocean and winds currents (while they move polewards due to convection) are deflected as they move towards the pole from the equator. Towards the North, they are deflected westwards while towards the South they are deflected eastwards.
