When roan cattle are mated, 25% of the offspring are red 50% are roan and 25% w e upon
examination, it can be seen that the coat of a roan cow consists of both red and white hans by what
this trait controlled?
A Multiple alleles
B Co-dominant alleles
C. Incomplete dominance genes
D. Dominant inheritance

B Co-dominant alleles

Explanation: The coat of a roan cow consists of both red and white because the two alleles are codominant. Codominance occurs when two alleles outwardly express themselves equally. In codominance, neither of the allele is completely dominant rather they are equally dominant. None is able to mask the effect of the other. The two alleles express themselves equally in the phenotype of the organism. This means that in a roan cow, the allele for white fur is dominant and the allele for red fur is equally dominant, thus they manifested equally as a mixture of both red and white furs.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
