1 through 5 please

1)Consider a small population of 20 individuals with three genotypes, AA, Aa, and aa particular phenotype. The relative fitnesses of the Each genotype correspon phenotypes are as follows would you expect to even , 10 Waa = 1.0 n the population?Select one Which of the alleles become. a. Either allele is equally likely to becoid lixed b. a c. A 2) If q is the frequency of the recessive allele in a population and q-0.421, what is the frequency of the homozygous dominant individuals? Input your answer, including THREE decimal places. 3) Consider the genotypes and phenotypes of the bead population used in lab (AA-blue, Aa green, aa-yellow) A blue and a yellow bead are chosen to mate. If blue and yellow are generation 0, what fraction of generation 2 do we expect to be yellow? Enter your answer below, to two decimal places 4) When one population's size is smaller than another, the probability of a particular allele being fixed (all else being equal) is larger or smaller 5)A population has 2 red (RR), 4 purple (Rr), and 2 blue () individuals. What are the allele frequencies of this population of 8 individuals? Select one: a. 0.7 R and 0.9 r b. 0.5 R and 0.5r c. 0.25 R and 0.75 r d. 0.1 R and 0.9r

Explanation / Answer

Either allele is fixed.

q= 0.421

Hence frequency of dominant allele is 1-q= 1-0.421= 0.579

Frequency of dominant allele is 0.579

as per the mendels law of segregation in generation 2 the typical ration of possible genotype is 9:3:3:1 here 9 dominant and 3 and 3 heterozygous genotype were reported and only 1 recessive yellow genotype is observed.

frequency of recessive allele aa = no. of recessive allele in progeny/ total number of progeny

                                             = 1/ 16

                                            =0.062

Hence 0.062 are yellow.

Answer is: larger

Smaller population have less ability to adapt means responds to favorable condition. Individuals in small population have less adaptive capacity with respect to changing environment. Genetic drift is very high in small population hence probability of allele being fixed in smaller population is larger.

R= 0.5

r= 0.5 here out of total 8, equal numbers of allele are observed. 4 RR and 4 rr (in general) hence the answer is 0.5 R and 0.5 r
