Species A : 2N = 24, N = 12
Species B : 2n = 26, n = 13
During the hybridization N + n = 25
1. DDAA, DdAa

5. The phenotypic ratio is 9:3:3:1 where 9 combinations will produce offspring with both dominant phenotypes (dimples and brown hair), 3 will produce offspring with one dominant phenotype and one receive phenotype (dimples, blonde hair), 3 will produce offspring with one receive phenotype and one dominant phenotype (no dimples, brown hair), and one will produce offspring with both recessive phenotypes (no dimples, blonde hair)
The capsid surrounds the virus and is composed of a finite number of protein subunits known as capsomeres, which usually associate with, or are found close to, the virion nucleic acid
Pressure decreases with increasing altitude.
D. it serves as a link between membrane proteins on adjacent membranes.
