<span>Geologists searching for clues to the ancestors of modern-day vertebrate land animals should look in layer 2 , of the fossil beds.
As the fossils get older, the fossils will be buried deeper within the layer of the fossil beds. Within layer 2 of the fossil beds, Geologist could found the fossils that came from ancient sera Valli an age</span>
Answer:
there is a 100% chance it will contain the recessive allele and a 50% chance it will have the recessive trait
I tried to attach a document I made of a punnet square to help further explain
Explanation:
Answer:
1. At the end of S phase- 20 pg DNA
2. At the end of G2 phase- 20 Pg DNA
Explanation:
The cell before undergoing M phase undergoes the steps of interphase that is G₁, S and G₂ phase.
During S phase, the process of cell replication takes place which replicates the DNA as a result of which the amount of DNA doubles. This DNA amount is reduced to half during the anaphase stage of M phase.
In the question since the amount of DNA is 10pg therefore the amount will be double during S phase and becomes 20 pg and will remain 20 pg until the DNA is distributed therefore at the end of G₂ phase Will remain the 20 pg.
Crossing over is important because it creates genetic variability.
<h3>What is crossing over?</h3>
It is the exchange of chromosomal segments between non-homologous chromosomes in a tetrad.
Since chromosomal segments contain genes at different loci, the exchange will increase the genetic variability of the new chromosomes.
Thus, the daughter cells carrying the recombined chromosomes will be genetically variable from not just the parent cell, but fellow daughter cells.

Tubes for Transporting Food-carrying tubes Phloem Water-carrying tubes Xylem Sugar is produced In the leaves. The food-carrying tubes transport this sugar from the leaves to the other parts of the plant. The root hairs found on the roots Take in water and mineral salts from the soil.
