Percentage score will be displayed along with right answers.

1. Gene is a
segment of aminoacid sequence that codes for a functional polypeptide
segment of DNA that codes for proteins and RNAs
segment of DNA that codes for functional polypeptide
segment of mRNA that codes for functional polypeptide
2. Alleles are
alternative forms of a protein
alternative forms of mRNA
alternative forms of gene

epistasis
back cross
test cross
dominant epistasis
4. Alleles are located on the
same locus of homologous chromosomes
different locus of homologous chromosomes
same locus of sister chromatids
different locus of sister chromatids
5. A cross involving two allelic pairs (WWYY X wwyy)is called
