Please help!! (genotype question) In sheep white wool (W) is dominant over black wool (w). What genotypic ratio is expected from a cross between a heterozygous sheep with white wool, and a sheep with black wool?

    W     w

 w  Ww  ww

 w Ww   ww

Explanation:

the white sheep has Ww and the black has a ww since white is a dominate and heterozygous implies it has 2 versions of a gene not 2 copies of the same one so  there would be a 50% chance of a white sheep with a copy of the black wool trate and a chance  50% of a black sheep

b

explanation:

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
