The correct answer is 9:3:3:1
When two homozygotes for two traits cross, the phenotypic ratio of the offspring is 9:3:3:1 ( unless other factors like epistatic interaction change the inheritance model).
In our case, we have two simple traits of seed color and seed shape that follow the Mendelian model of inheritance.
In this dihybrid cross, we have
9/16 of the offspring expressing both dominant traits ( yellow and round seeds)
3/16 expressing one dominant and one recessive trait ( yellow and wrinkled)
3/16 expressing the other dominant and recessive trait (green and round)
1/16 expressing both recessive traits ( green and wrinkled)

Answer:
This question is incomplete because of the absence of the data referred to in the question
Explanation:
This question is incomplete but the data referred to in the question is attached below
In order to determine the median value of any set of data, the data is first of all rearranged chronologically (ascending) and then the middle value is picked if the number of data is odd but if the number of data is even, the two middle values are added together and then divided by two to get the median.
From the data provided, the values (which are 10 in number) can be arranged as shown below (with the median values in bold)
Females: 5, 7, 7, 7.5, 7.5, 7.8, 7.8, 8, 8, 17
Males: 4.5, 7.5, 9, 9, 9.2, 9.3, 10, 10, 10.5, 13
Since the number of data is even, the two middle numbers (in bold) shall be added together and then divided to get the median as shown below
The median value for the females foot width is = 7.5 + 7.8/2 = 7.65 cm
The median value for the male foot width is = 9.2 + 9.3/2 = 9.25 cm
