The food sources available for a particular species in an ecosystem. Also space where they can live and reproduce, but food is the main factor.
Answer:
flooding
Explanation:
The hurricane brings in enormous amounts of rainfall with it, often resulting in flooding. The ground squirrels in this scenario live relatively close to the ocean shore. They live in burrows, spending big portion of their time in them, as well as having their young ones sheltered in them. The heavy rainfall and the flooding of the area will result in filling the burrows with water. The damage for the population of ground squirrels will be enormous, with their young ones all drowning for sure, and the majority of the adults getting drowned as well, or maybe even all of them. Hope this helps!!!!!
Answer:
How much of the population would be h o m o z y g o u s dominant?
A. 84%
Answer and Explanation:
<u>Cross:</u> aa Bb dd Ee x AA bb Dd Ee
We can calculate the probability of getting heterozygous individuals in the progeny by using the <u>product rule</u>. Assuming that these four genes <u>assort independently</u> (<em>events that occur independently from each other</em>), we can infer that the F1 will have the next genotypic proportions for each gene:
1) aa x AA
F1) 4/4=1 Aa
2) Bb x bb
F1) ½ bb
½ Bb
3) dd x Dd
F1) ½ dd
½ Dd
4) Ee x Ee
F1) ¼ EE
2/4 = ½ Ee
¼ ee
So, to know what the probability is that the F1 of being heterozygous for all loci, we must multiply the respective individual probabilities of getting a heterozygous genotype, like this:
1 Aa x ½ Bb x ½ Dd x ½ Ee = 1/8 AaBbDdEe
It is only one nuclei in a cell
