Two genes of a flower, one controlling blue (B) versus white (b) petals and the other controlling round (R) versus oval (r) stamens, are linked and are 10 map units apart. You cross a homozygous blue-oval plant with a homozygous white-round plant. The resulting F1 progeny are crossed with homozygous white-oval plants, and 1,000 F2 progeny are obtained. How many plants of each of the four phenotypes do you expect?

Termination is a normal and important function at the ends of genes. There, sequences called terminators trigger the elongating polymerase to dissociate from the DNA and release the RNA chain it has made, In bacteria, terminators come in two types: Rho-dependent and Rho-independent, choose correct statements about this;
Rho-dependent |
a- rut sites |
b- has an ATPase activity |
|
Rho-independent |
c- terminates only those transcripts still being transcribed beyond the end of a gene or operon |
d- intrinsic terminator |

Two varieties of maize averaging of 180 cm and 20cm, inches in height respectively, are crossed. The F1 progeny is quite uniform averaging 100cm in height. How many different Phenotype express in f2 generation?
