The purple kernel is dominant over the yellow kernel and hence it has the genotype of homozygous dominant PP.

<h3>What is Genotype?</h3>

Genotype may be defined as the ultimate combination of alleles of genes that are selected for specific studies.

If it has some offspring with purple kernels and some with yellow, the genotypes of the two parents are heterozygous dominant for the purple kernel, i.e. Pp and Pp.

And when these two parents are crossed with each other, the genotypes are PP, Pp, Pp, and pp. While the genotypic ratio is 1:2:1 (PP: Pp: pp), but the phenotypic ratio is 3:1 (Purple: Yellow).

Therefore, it is well described above.

Factorize this polynomial function <br>x³-7x+6<br>Hint:x³-7x+6​=0
dolphi86 [110]

Answer:

(x - 1)(x - 2)(x + 3)

Explanation:

f(x)=x3-7x+6 Since (a + b + c + d = 0), then f(1) = 0 --> one factor if (x - 1).

After division -->

f(x)=(x-1)(x2f2+x-6). The trinomial in parentheses can be factored.

Find 2 numbers knowing sum (1) and product (-6). They are -2 and 3.

Therefor, f(x)=(x-1)(x-2)(x+3)
