What does a 3 1 phenotype mean?.

1 answer:

Kisachek [45]1 year ago

3 0

3:1 phenotype ratio means that three offspring will have a dominant phonotype. Then there is one offspring that will have a recessive genotype, and thus the recessive phenotype.

A 3:1 ratio is the relative fraction of phenotypes among progeny (offspring) results following mating between two heterozygotes, where each parent possesses one dominant allele and one recessive allele at the genetic locus in question.

A phenotypic ratio is a quantitative relation between phenotypes showing the number of times the frequency of one phenotype correlates with another.

A monohybrid cross results in a phenotypic ratio of 3:1.

Luke, Kira and Ali each served 2/3 of their own cake. Each cake was the same size, but luke served 4 slices, Kira served 6 slice

r-ruslan [8.4K]

Answer:

The whole slices of the cakes of Luke, Kira and Ali are 6, 9 and 12 respectively. So it is possible.

Step-by-step explanation:

It's possible because they cut cakes into different number of slices.

You know that Luke, Kira and Ali each served $\frac{2}{3}$ of their own cake and Luke served 4 slices, Kira served 6 slices and Ali served 8 slices.

Being x the whole slices of cake, and if Luke served $\frac{2}{3}$ of his cake, which are 4 slices, the whole slices of cake of Luke is:

$\frac{2}{3}*x=4 slices$

Solving:

x= 4 ÷ $\frac{2}{3}$

x= 6

Then, whole slices of Luke's cake is 6.

Performing the same approach for Kira you get:

$\frac{2}{3}*x=6 slices$

x= 6 ÷ $\frac{2}{3}$

x= 9

Then, whole slices of Kira's cake is 9.

Finally, performing the same approach for Ali you get:

$\frac{2}{3}*x=8 slices$

x= 8 ÷ $\frac{2}{3}$

x= 12

Then, whole slices of Ali's cake is 12.
