Two codominant alleles, lm and ln, determine the human mn blood type. suppose that the lm allele occurs with a frequency of 0.80 in a population of eskimos on a small arctic island. match the expected frequencies to the m, mn, and n blood types in the population on the island for two mating scenarios: if random mating occurs, and if the inbreeding coefficient for this population is 0.05. mm frequency mn frequency nn frequency answer bank mating scenario random mating inbreeding coefficient of 0.05 0.040 0.640 0.648 0.320 0.048 0.304

Explanation:

Let p be the frequency of LM Allele and q is the frequency of LN Allele

Two alleles are Co-dominant

and p=0.8

so q=1-p=1-0.8=0.2

and inbreeding coefficient or F=0.05 (it is the degree to which two alleles are more likely to be homozygous rather than heterozygous)

The frequency of Homozygotes LMLM = (1-F) p2 +Fp

=p2-Fp2+Fp

=p2+Fp(1-p)

=p2+Fpq

Therefore, The frequency of Homozygotes LMLM in the Eskimo population will be

f(LMLM)= (0.8)2 + 0.05 (0.8) (0.2)

=0.648

Similarly The frequency of Homozygotes LNLN = q2+Fpq

or f(LNLN) = (0.2)2+0.05 (0.8) (0.2)

=0.048

And The frequency of Heterozygotes LMLN =2pq (1-F)

f(LMLN) = 2 (0.8)(0.2) (1-0.05)

=0.304

The expected frequencies of different blood types are

f(MM)=0.648, f(MN)=0.304, f(NN)=0.048

i have to report this, it doesn't relate to biology

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
