Answer:
Ss × ss
Explanation:
This question involves a single gene coding for hair length in guinea pigs. The alleles for short hair (S) is dominant over that of long hair (s).
According to this question, a guinea pig with short hair (S_) is crossed to one that has long hair (ss) to produce offsprings that have 44 short hair and 46 long hair. This number of offsprings produced indicate a ratio of 1:1, which can only be produced if the short haired guinea pig is heterozygous i.e. Ss.
Therefore, the genotype of the parents are Ss (short hair) and ss (long hair) i.e. Ss × ss. This combination will produce offsprings with the following proportion: Ss (1) : ss (1).
A hydrometer is an instrument that measures the specific gravity (relative density) of liquids. The ratio of the density of the liquid to the density of water. A hydrometer is usually made of glass, and consists of a cylindrical stem and a bulb weighted with mercury or lead shot to make it float
D) #recombinant=116+601+4+2+113+625=1462
#nonrecombinant=2538+2708=5246
RF=R/(N+R)=1462/6708=0.2
E) I=1-Q
I-interference
Q-coefficient of coincidence
Q=O2Xo/E2xo(2xo-double crossovers)
O2xo=6
P=(distance from C1 to Sh/100)*(distance from Sh to Wx/100)
=(3.38/100)*(18.28/100)=0.006
E2xo=0.006*6708=40.248
Q=6/40.248=0.15
I=1-0.15=0.85
Answer:
Regulated gene expression is crucial to the proper growth & survival of an organism and cannot be over-emphasized. Without it, the genetic code of a chromosome is the equivalent of a computer data file without the appropriate application to run it.
The part of the enzyme molecule that binds to its associated substrate is ACTIVE SITE.
The active site contains the catalytic groups which are amino acids which promote the formation and the break down of bonds. By breaking and forming new bonds, the enzyme substrate interaction brings about the formation of the transition state.
