Question
Assume that eye color in fruit flies is a Mendelian trait. Red eye coloration is dominant and white eye coloration is recessive for this trait. A population of fruit flies has 608 individuals total. 122 individuals are homozygous dominant, 60 individuals are heterozygous and 426 individuals are homozygous recessive. la. What is the observed frequency of heterozygous individuals in this population? A. 0.70 B. 0.25 C. 0.10 D. 0.75 lb. According to the Hardy-Weinberg Principle, what is the frequency of the dominant allele in this population? A. 0.20 B. 0.10 C. 0.75 D. 0.25 2. Geckos are a type of lizard. Which of the following is/are variations in the population of geckos that would be subject to natural selection? A. Some baby geckos learn to jump a small creek to find a richer food source than others nearby. B. Calcium is a limited resource for geckos, one year a lot of calcium is available which allows for more growth than normal. C. A few of the geckos have more "grippers" on their foot pads that allows them to climb higher into trees and reach food sources that others can't. D. B and C 3. What variable in the Hardy-Weinberg equation expresses the heterozygous genotype? D. None of the answers are correct 4. ardy-Weinbere.eauilibrium? M n he rds English (US)Explanation / Answer
In Hardy-Weinberg equation, the variable for heterozygous genotype is 2pq.
5 factors important for Hardy-Weinberg equilibrium are-
*gene migration or gene flow
*genetic drift
*mutation
*genetic recombination
*natural selection.
An alternative form of a gene that occurs in the same place on a homologous chromosomes is allele.
