If 10 pairs of genes were considered in an individual, how many different garnet

Question

If 10 pairs of genes were considered in an individual, how many different garnets can he formed if five of the gene pairs are homozygous and the remaining 5 gene pairs are heterozygous? 10 20 32 1024 the number of different gametes cannot he determined A set of Neurospora mutants defective in single steps in a pathway were identified that required supplementation by compound X. Precursors of compound X included compound Y, which could he changed directly to compound X, and compounds A and B that each could he changed into compound Y So A rightarrow Y rightarrow X B rightarrow You would expect some mutants would be rescued by supplementation by Y, some by supplementation by A, and some by supplementation by B no mutant would be rescued be supplementation by Y supplementation by A and B would rescue all the mutants supplementation by A or B would rescue all the mutants none of the above

Explanation / Answer

3) 10 pairs of genes were considered in an individual ,how many different gametes can be formed if five of the gene pairs were homozygous and remaining 5 are heterozygous then,

There are 5 genes that have to change i.e, probability is 2^5

2*2*2*2*2=32

ANS is C

4) A set of neurospora mutants defective in single steps in a path were identified that required supplementation by compound X. precursors of compound X included compound Y, which could be changed directly to compound X and compounds A and B that each could be changed into compound Y

a)some mutants would be rescued by supplementation by Y ,some by supplementation by A, and some by B.
