It is estimated that every human carries at least one recessive lethal allele (i.e. they are heterozygotes at that locus). What maintains these alleles in populations given their lethality when homozygous? Group of answer choices heterozygote disadvantage mutation/selection balance inbreeding genetic drift

Under the above conditions of reproductive discrimination against those with attached earlobes, if the population in this next generation is still 500,000 people, then the new genotypic frequencies will be: Homozygous dominants, unattached ear lobes: 0.34 Heterozygotes, unattached ear lobes: 0.48 Homozygous recessives, attached ear lobes: 0.18 What will be the allele frequencies for L and l in this generation? Did the frequency of the recessive allele (l), as compared to its frequency calculated in Part B, increase or decrease because of its deleterious effects on fitness? Does the possession of the recessive allele kill those who possess it? If those with attached ear lobes continue to be only half as successful in securing mates in each successive generation, what will happen to the frequency of the recessive allele in this population?
In a population experiencing no selection, genetic drift, gene flow, mutation or non random mating, the allele frequencies at a locus where the R allele is dominant over the r allele, are as follows. R= 0.3 r=0.7 What is the expected heterozygosity of the population at that locus?

p + q = 1 p2 + 2pq + q2 = 1 p is the frequency of the dominant allele q is the frequency of the recessive allele p2 is the frequency of homozygous dominant genotype q2 is the frequency of homozygous recessive genotype 2pq is the frequency of heterozygous genotype Within a population of roses, the color red (R) is dominant over the color white (r). 40% of all the roses are white.a)The percentage of roses in the population that are heterozygous b) The frequency of homozygous dominant individuals =
In a population of 100 individuals, there are exactly 16 individuals expressing the recessive phenotype for a trait controlled by a single diallelic locus (i.e. a diploid organism). If the population is at genetic equilibrium, how many heterozygous individuals would you expect to find? 48 36 84 cannot be determined 16
Assuming a Hardy-Weinberg equilibrium, 21% of a population is homozygous dominant, 50% is heterozygous, and 29% is homozygous recessive. What percentage of the next generation is predicted to be homozygous recessive? Group of answer choices 53% 29% 42% 58%
Fur colour in mice is a single gene trait controlled by two alleles. In a population of 75 mice, 21 are homozygous dominant, 37 are heterozygous dominant, and 17 are homozygous recessive. What is the frequency of the dominant allele in the population? Show all work and record your answer as a value between 0 and 1 rounded to two decimal places.
Tay Sachs disease is an autosomal recessive disease. Among Ashkenazi Jews, the frequency of Tay Sachs disease is 1 in 1000. If the Ashkenazi population is mating randomly for the Tay Sachs gene, how many people in the population of 1000 are expected to be heterozygous carriers of the Tay Sachs disease (assume this population is in Hardy-Weinberg equilibrium)? No carriers would be in this population 1 61 564
Among a particular population of 100 plants, red flowers are dominant and yellow flowers are recessive. F is the dominant allele and f is the recessive allele. 40 plants are homozygous dominant • 44 plants are heterozygous 16 plants are homozygous recessive Use the Hardy-Weinberg equation to calculate the equilibrium frequencies of each genotype
Why can all the allele and genotype frequencies in a population be determined based on the number of recessive individuals in the population? Recessive individuals are represented by only q2 and dominant are represented by both 2pq and p2 Recessive individuals are represented by only p2 and dominant are represented by both 2pq and q2 Recessive individuals are represented by q and dominant are represented by p Recessive individuals are rare and thus less in numbers making it easier to calculate

On the off chance that gene A/an isn't in Hardy-Weinberg equilibrium because of natural selection to such an extent that people with the genotype AA have a fitness of 1.0, heterozygotes have just marginally decreased fitness at 0.9, and people with the genotype aa have a fitness estimation of 0.6, what sort of progress in allele recurrence/frequency would you hope to see over the long haul accepting you start with equivalent frequencies of the 2 alleles?
