In recessive lethal diseases such as tay-sachs disease, carriers have one copy of the normal allele and one copy of the allele for the disease. carriers are represented in the hardy-weinberg formula by

The hardy weinberg formula is: p2 + 2pq + q2 = 1 Homozygous dominant (healthy) is represented by p2 while homozygous recessive (diseased) is represented by q2. This leaves 2pq as the heterzygous carrier, as it has one p allele and one q allele.

A) 4 amusingb)alpha particle is a helium nucleus. it contains 2 protons and 2 neutrons.c)alpha particle has charge of +2.
