True they can be man made and naturally made.
N positron emission, also called positive beta decay (β+-decay), a proton in the parent nucleus decays into a neutron that remains in the daughter nucleus, and the nucleus emits a neutrino and a positron, which is a positive particle like an ordinary electron in mass but of opposite charge.
Answer:
1. First calculate the distance of the map for trace (eg) and spastic mutation (sps); Recombinant frequency:
vg + sps + vg sps + = 99 + 97 = 196
we are going to divide 196 by 650 (total descendants) = 0.3.
in the next step we are going to calculate the recombinant frequency 0.3 * 100 = 30 mu or cM or 30%
this shows that there is an association between vestige (eg) and spastic mutation (sps) since the recombinant frequency is less than 50%.
The squareness test is not valid because the combining frequency is far from 50%.
2. Results:
1. Genes are linked.
3. The test rejected the independent assortment law because it is not true that there is a 1: 1: 1: 1 relationship between descendants
