Answer:
1/2
Explanation:
Let's assume that the allele "p" is responsible for PKU in the homozygous state. According to the given information, both the parents are unaffected by the disorder but have an affected child. This means that both the parents carry at least one copy of the recessive allele responsible for the disease. Therefore, the genotype of each of the parents is Pp. A cross between Pp and Pp would produce progeny in following ratio=
Pp x Pp = 1/4 PP: 1/2/ Pp: 1/4 pp
Therefore, the probability that their next child will carry just one recessive allele is 1/2.
Hypotonic - because there is a higher concentration inside the cell than outside of it
Usually the y-axis stands for dependent variable while the x-axis stands for independent variable. And the curve stands for the relationship between the two variables. The control variable and measurement variable often means the independent variables.
Answer
100 percent
Explanation:
If you cross rr and RR you get four offspring with the trait Rr. Since there is one capital letter, they will all exhibit the dominant trait. Hope this helped!
