Trong một quần thể heo tính mẫn cảm đối với một bệnh được xác định bởi hai alleles: B and b. Heo có kiểu gen bb sẽ có
bệnh, Bb và BB không bệnh. Tần số của allele B = b = 0.5. Hai
con heo đều có kiểu gen Bb giao phối với nhau và sinh ra một
lứa 10 heo con. Hãy tính:
a) Số heo con có khả năng mang bệnh

the answer is otpion c) understanding

he wants to be heard one more time. he wants to be understood. he needs the truth one more time.

the principle of segregation describes how pairs of gene variants are separated into reproductive cells. from his data, mendel formulated the principle of segregation. we now know that the segregation of genes occurs during meiosis in eukaryotes, which is a process that produces reproductive cells called gametes.

the species living around the vents are especially good at dispersal.  

deep-sea vent originates on the floor of the ocean when seawater circulates through hot volcanic rocks, usually situated where the new oceanic crust is being produced.  

biological dispersal refers to the movement of species from their location of birth to their site of breeding, or from breeding site to another. similarly, the oceanic dispersal refers to the movement of the species from one land mass to another by sea crossing.
