Question

a population of aliens with similar genetics as humans is affected by a homozygous recessive condition known as \xbziq.\ this condition causes aliens to die at young ages because their digestive tracts are not able to effectively process food and obtain the necessary nutrients and energy from their diets. approximately 2% of the newborn aliens have the xbziq condition. what is the carrier (heterozygote) frequency in the population? 14% 2% 86% 24% 12%

Explanation:

Step1: Define homozygous recessive frequency

Let \( q^2 = 0.02 \) (2% of population has xbziq).

Step2: Calculate q

\( q = \sqrt{0.02} \approx 0.1414 \)

Step3: Calculate p

\( p = 1 - q \approx 1 - 0.1414 = 0.8586 \)

Step4: Calculate carrier frequency

Carrier frequency = \( 2pq \approx 2 \times 0.8586 \times 0.1414 \approx 0.24 = 24\% \)

Answer:

24%
