Describe how inbreeding affects genotypic frequencies? Describe how outbreeding affects genotypic frequencies?
Homework Answers
Dear Student,
* Inbreeding is the process of producing offsprings by mating between very closely (genetically )related organisms.
With continuous inbreeding , the genetic variation will be lost and thereby homozygosity increases.This can increase the chances of offsprings getting affected by the recessive traits from consanguinity . Examples of such disorders include increased infant mortality rates, decreased immune function, etc.
* Outbreeding : Outbreeding is the process of producing offsprings by mating between the organisms which are not genetically closely related.
It increases genetic diversity and decreases the probability of the individual getting affected by disorders due to genetic abnormalities .
Hope you are clear..?

Calculating expected genotypic frequencies and individuals in a population from allele frequencies: 3.1 In a population of peas, the frequency of the dominant allele for a purple flower is 0.77 and the frequency of the recessive allele for a white flower is 0.23. What would the genotypic frequencies be if the population is in equilibrium? _____ = Frequency of homozygous dominant individuals _____ = Frequency of heterozygous individuals _____ = Frequency of homozygous recessive individuals How many individuals would you...

2. Which of the following correctly describes how inbreeding will affect genotype and allele frequencies in Hardy-Weinberg populations? Genotype and allele frequencies will be unaffected. The frequency of heterozygotes will decrease, but allele frequencies will be unaffected. The frequency of homozygotes will increase, and deleterious alleles will decrease. Beneficial alleles will increase in frequency, as well as the genotypes containing those alleles. Genotype frequencies will return to H-W expectations after 1 generation of random mating. 3. Consider a population with...

Question: "Determine the genotypic frequencies of offspring for a genetic trait with two alleles, R and r, with the previous generation's allelic frequencies of R=0.1 and r=0.9." My professor said that you can use the formula p^2+2pq+q^2=1 where R=p and r=q, but i'm not entirely sure how to go about this. -Population practicies random mating (no picking your mates) -No immigrration or emigration (i.e., a closed population)

Give the Hardy–Weinberg expected genotypic frequencies for an autosomal locus with three alleles, where the frequencies of alleles A1, A2, and A3 are defined as p, q, and r, respectively. Set the problem up and show your work. Tay–Sachs disease is an autosomal recessive disorder. Among Ashkenazi Jews, the frequency of Tay–Sachs disease is 1 in 3600. If the Ashkenazi population is mating randomly for the Tay–Sachs gene, what proportion of the population consists of heterozygous carriers of the Tay–Sachs...
