Planting pollen and nectar plants
Answer:
a) interphase(G2)
Explanation:
<em>The nucleus would contain 6 pg of DNA at the interphase (G2) phase of the cell cycle.</em>
The cell cycle is characterized by tow main phases, namely;
- The interphase
- The m phase
The interphase is divided into G0, G1, S, and G2 phase respectively while the m phase is divided into prophase, metaphase, anaphase and telophase respectively.
At the S phase of the interphase specifically, DNA is replicated and the amount of DNA in the cell becomes double.
<u>Hence, a cell whose DNA amount ranges from 3 - 6 pg will have exactly 6 pg after the S phase of the interphase, which is G2 phase.</u>
The correct option id a.
Answer: Which layer is older than Layer 6?

-Layers 2 and 3
Which layers were deposited before layer 5?
- Layers 7 and 9
Explanation: It explains it in the picture
loess - a deposit of fine, mineral-rich soil that is good for agriculture
deflation - the process by which wind moves particles that are loose
sand dune - sand deposited against an obstruction
abrasion - the process by which wind wears down solid objects

Answer:
The correct genotype of the two pure lines and the F1 is:
A⁺A⁺B⁰B⁰C⁰C⁰D⁰D⁰ and A⁰A⁰B⁺B⁺C⁺C⁺D⁺D⁺
The number of additive alleles on each genotype are two and six respectively.
Explanation:
Locus( plural form . loci) are fixed point on a chromosome in which genes are located. These genes are specific genetic material or genotype.
Now;
If we decide to designate the allele of the four loci into either additive (⁺) or non-additive(⁰); we have the following :
Let's the allele of the four loci to be
A⁺/A⁰, B⁺/B⁰, C⁺/C⁰ and D⁺/D⁰
However, from the diagram below; we deduce that the correct genotype for the two pure lines and the F1 is as follows:
A⁺A⁺B⁰B⁰C⁰C⁰D⁰D⁰ and A⁰A⁰B⁺B⁺C⁺C⁺D⁺D⁺ and the number of additive alleles on each genotype are two and six respectively.
The cross between both F1 traits will yield an heterozygous individual for the offspring. i.e A⁺A⁰B⁺B⁰C⁺C⁰D⁺D⁰ with only four additive allele
