Answer:
Option (B).
Explanation:
The relationship between closely related species can be studied by their evolutionary tree. The two species are closely related if they have similar characteristics and nucleotide sequence.
Species A has the DNA sequence TAGCTTAGGGACGG whereas species B has the DNA sequence TACCTTAGGGACGG. These two species have identical nucleotide sequence with minor differences. Hence, these two species are closely related with each other.
Thus, the correct answer is option (B).
Glands are classified as ENDOCRINE or EXOCRINE depending on their route of secretion. ENDOCRINE GLANDS secrete their products, called hormones, directly into the blood. ... Their products are NOT released into the blood. Exocrine glands are classified on the basis of the number of cells making up the glands.
We first check the first parent's possible alleles: OT, Ot, OT, Ot. (Combinations of the 2 O-alleles and T-alleles given).
A similar process is used for the second: OT, Ot, oT, ot
Genotypes: Check the attachment. We combine the alleles from each parent (for example, Ot + oT = OoTt). We do this for all 16 combinations.
Genotype Likelihoods: We count each of the possible results and tabulate the number of times each appears, and divide by the total number of combinations (16).
OOTT: 2/16 = 1/8 = 0.125
OOTt: 4/16 = 1/4 = 0.25
Oott: 2/16 = 1/8 = 0.125
OoTT: 2/16 = 1/8 = 0.125
OoTt: 4/16 = 1/4 = 0.25
Oott: 2/16 = 1/8 = 0.125
Phenotypes: Check attachment. Based on the genotypes, use the dominant gene if at least one is dominant (Ex. Oo = O, oo = o)
Phenotype Likelihoods: We count the number of each possibility, only 2 of which are present: OT and Ot, then divide by the total number of combinations, which is 16.
OT: 12/16 = 3/4 = 0.75
Ot: 4/16 = 1/4 = 0.25
Biological species is the term for a group of interbreeding organisms that are able to produce fertile young.
