You cross two true-breeding parents (one with yellow seeds and one with green seeds), grow and self-pollinate the F1 generation,

and then count the number of offspring with yellow and green seeds in the F2 generation. If you counted 2,000 offspring and there was a 3:1 ratio of yellow:green seeds, how many offspring would have yellow seeds?

Answer:

1500

Explanation:

Let's assume that the allele for yellow seed color is "Y" and the allele for green seed color is "y". Genotype of pure breeding yellow seeded plant would be "YY" and that of the green seeded plant would be "yy". A cross between YY and yy gives all heterozygous yellow seeded plants (Yy) in F1 progeny. Self pollination of two F1 plants (Yy x Yy) obtains F2 generation in 3 yellow: 1 green ratio.

The total population size of F2 generation = 2000

The proportion of yellow seeded plants in F2 generation = 3/4 (since the F2 phenotype ratio is given 3 yellow: 1 green)

Therefore, total number of yellow seeded plants in F2 progeny = 3/4 x 2000= 1500

How do you calculate acceleration?
olasank [31]
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

What are TWO functions of citric acid in the feta cheese? What are the TWO functions of agar in the feta cheese?
Vinvika [58]

Answer:

The following are the two functions of citric acid in the feta cheese:  

1. Coagulation, that is, the chemical reaction of citric acid with proteins in milk leads to separation of curd and whey.  

2. The citric acid functions as a chelating agent, which is required for syneresis, that is, for controlling the moisture content.  

The following are the two functions of agar in the feta cheese:

1. Feta means to slice, and agar offers sliceable texture to the feta cheese as it produces a solid gel-like composition.  

2. It is a vegetarian alternative for gelatin and exhibits higher gelling properties.
