In pea plants, the trait for green seed pods (G) is dominant over the trait for yellow seed pods (g). Which cross will produce t
he maximum number of offspring with green seed pods?
1 answer:
Explanation:
according to Mendel's law taking the color as an example for pea plants.
here the trait for green seed is dominant (G) and the trait for yellow seed (g) are recessive. cross of (G)(G) in generation F1 in order to produce maximum number of off-spring with green seed. look below in the picture

Complete Question
A commuter train passes a passenger platform at a constant speed of 39.6 m/s. The train horn is sounded at its characteristic frequency of 350 Hz.
(a)
What overall change in frequency is detected by a person on the platform as the train moves from approaching to receding
(b) What wavelength is detected by a person on the platform as the train approaches?
Answer:
a
b
Explanation:
From the question we are told that
The speed of the train is
The frequency of the train horn is
Generally the speed of sound has a constant values of
Now according to dopplers equation when the train(source) approaches a person on the platform(observe) then the frequency on the sound observed by the observer can be mathematically represented as
substituting values
Now according to dopplers equation when the train(source) moves away from the person on the platform(observe) then the frequency on the sound observed by the observer can be mathematically represented as
substituting values
The overall change in frequency is detected by a person on the platform as the train moves from approaching to receding is mathematically evaluated as
Generally the wavelength detected by the person as the train approaches is mathematically represented as
