Blood typing in humans depends on three alleles. The A and B alleles are codominant, and the O allele is recessive. An AB blood

type mother has children with a B blood type father (genotype BO). What are the chances that their children will have AB type blood?

Answer:

25%

Explanation:

If a mother of blood type AB has children with father of blood type BO than there is a 25% chance that they had a child with blood type AB.

As the mother has two alleles A and B.

Father has two alleles B and O. So there are total of 4 sequences AB, AO, B, and BO.

AB 25%

AO 25%

B 25%

BO 25%

<h2>Mutation & genetic drift</h2>

Explanation:

  • A mutation is characterized as a lasting change to the DNA succession in a quality. This change moves the hereditary message conveyed by the quality and can modify the amino corrosive arrangement of the protein the quality encodes. This implies future cells created by the quality will just convey a specific characteristic.  
  • Genetic Drift is the change in the hereditary structure of a populace after some time because of possibility or irregular occasions. In instances of hereditary float, for example, catastrophic events or periods of irregular climate, the age that makes due to repeat won't really be the fittest, yet the most fortunate. Hereditary float doesn't allude to a particular change in hereditary cells, rather to arbitrary events that impact a population's genetic makeup.
  • Hence, the right answer of the fill up the blank is "mutation and genetic drift".

In hummingbirds feather color is incompletely dominant. A rather large population of hummingbirds has 396 red-sided individuals
GrogVix [38]

Answer:

a) Frequency of the R allele: [(396 x 2) + 257] / (396 x 2) + (257 x 2) + (557  x 2) = 1049 / 2420 = 0.433

b) Frequency of the r allele: [(557 x 2) + 257] / (396 x 2) + (257 x 2) + (557  x 2) = 1371 / 2420 = 0.567

c) Frequency of the R allele: [(196 x 2) + 257] / (196 x 2) + (257 x 2) + (557  x 2) = 649 / 2020 = 0.321

d) Frequency of the r allele: [(557 x 2) + 257] / (196 x 2) + (257 x 2) + (557  x 2) = 1371 / 2020 = 0.679

e) migration is gene flow  

Explanation:

Gene flow (also referred to as gene migration) is the movement of genes that acts to change allele frequencies in local populations by transferring genetic material from one population to another. Gene flow may be caused either by the movement of organisms that reproduce in new populations (migration), or by the movement of gametes (for example, pollen dispersal in plants).
