Answer:
25%
Explanation:
Here's an example: two chickens have the phenotype of white feathers and brown feathers. What percentage of the chicks will have the recessive color? First, you have to see the parents' phenotypes. Draw a punnet square. Put one of the parent's phenotypes (w and B) on the top, and the other parent's (w and B) on the right side going down. Whichever trait is dominant (brown) MUST be capitalized. Then, cross the two parents. first box on the top left would read 'ww.' The one below it is 'Bw' (put the dominant first). The right top is 'Bw' and the one below it is 'BB'. So if there were 4 offspring, these would be their genotypes: 'ww', 'Bw', 'Bw', and 'BB'. The only offspring that would have the recessive trait is the 'ww' child, because dominant overpowers recessive. So 25% would have the recessive trait and 75% would have the dominant trait.
Answer:
The correct option is B) 1/4
Explanation:
Co-dominance can be described as a phenomenon which arises when the dominant trait is not fully dominant over the recessive trait. As a result, both the dominant and the recessive trait are shown in the organism.
To depict the results between two roan cows, lets make a punnet square:
R W
R RR RW
W RW WW
The results form the punnet square show that there is a 25% or 1/4 chance for the offspring produced to be a white cow.
