When the two genes in a dihybrid cross were situated on the same chromosome:
1. the proportion of parental gene combinations were much lower than the non-parental type.
2. the proportion of parental gene combinations were much higher than the non-parental type.
3. the proportion of parental gene combinations were equal to the non-parental type.
4. only the parental gene combinations were seen in the progeny.

Consider the given two statements:
Assertion (A): Genes that are linked do not assort independently.
Reason (R): Linked genes are located close to each other on the same chromosome and tend to be inherited together during meiosis, overriding Mendel’s law of independent assortment.
 
1. Both (A) and (R) are True and (R) correctly explains (A)
2. Both (A) and (R) are True and (R) does not correctly explain (A)
