What number should replace the letter [tex]$x$[/tex] in the "Seed color" row?

A. 18,066
B. 3,011
C. 207
D. 2,001


Sagot :

Let's analyze the seed color row in Mendel’s results. We know the number of yellow seeds, which is \( 6,022 \). We need to determine the proper number of green seeds that completes this row.

Given the options:
1. \( 18,066 \)
2. \( 3,011 \)
3. \( 207 \)
4. \( 2,001 \)

First, consider the traits for the yellow seeds and the sum of yellow seeds with each of the given options:

1. \( 6,022 \) yellow seeds + \( 18,066 \) green seeds = \( 24,088 \)
2. \( 6,022 \) yellow seeds + \( 3,011 \) green seeds = \( 9,033 \)
3. \( 6,022 \) yellow seeds + \( 207 \) green seeds = \( 6,229 \)
4. \( 6,022 \) yellow seeds + \( 2,001 \) green seeds = \( 8,023 \)

Looking at the consistent pattern of other traits, it's evident there needs to be a more balanced and consistent total considering Mendel's ratio.

When deciphering the characteristic ratio compared to similar grouped traits, the number that fits most closely to the expected balanced division and similar patterns seen, will be \( 6,022 + 2,001 = 8,023 \).

Thus, the number that should replace [tex]\( x \)[/tex] in the 'Seed color' row is [tex]\( 2,001 \)[/tex].
