<h2>Down Syndrome</h2>

Explanation:

Down syndrome is a genetic disorder caused when abnormal cell division results in an extra full or partial copy of chromosome 21

Down syndrome is a genetic disorder caused when abnormal cell division results in an extra full or partial copy of chromosome 21
Down syndrome is usually caused by an error in cell division called nondisjunction which results in an embryo with three copies of chromosome 21 instead of the usual two
Prior to or at conception, a pair of 21st chromosomes in either the sperm or the egg fails to separates
With development in embryo the extra chromosome is replicated in every cell of the body;this type of Down syndrome which accounts for 95% of cases is called trisomy 21
Maternal age is the only factor that has been linked to an increased chance of having a baby with Down syndrome resulting from nondisjunction;here environmental agents such as drugs, chemicals, and radiation act as mutagens which induce mutation in the fetus

Some "cleaner fish" consume parasites and mucus from the skin of larger fish. What would be a reasonable argument for why this c

marin [14]

This could be a mutualism rather than a commensal relationship because when<span> "cleaner fish" consume parasites and mucus from the skin of larger fish, they don't only receive food from the relationship, eliminating parasite and such from the large fish, but also they gain protection from predators, thus making the relationship a good example of mutualism, because both parts of the relationship gain something from the relationship itself. </span>

netineya [11]

<span>The ecosystem is the lowest level of the biosphere hierarchy to include weather patterns and soil conditions. in the whole biosphere hierarchy, ecosystem actually placed as the second highest (1 place below biosphere) But there are only 2 hierarchy that include weather and soils, and those hierarchies are biosphere and ecosystem. So technically the ecosystem will be the lowest in this matter</span>

There is a population where the frequencies of allele 1 and allele 2 are 0.7 and 0.3, respectively. Allele 1 has a selection coe

Lorico [155]

Answer:

0.8

Explanation:

There is a population where the frequencies of allele 1 and allele 2 are 0.7 and 0.3, respectively

Let's use GG to represent allele 1

Let's use gg to represent allele 2

So we can equally say that;

GG = p = 0.7

gg = q = 0.3 ( from Hardy-Weinberg Equilibrium)

So, given that the selection coefficient = 0.2

We known that the cross between GG and gg will definitely results to (GG,Gg and gg)

Then the fitness of these genes can be represented as:

1 - s, 1 and 1 - t respectively.

Thus. the allele 1's genotype fitness can be determined as

= 1 - s ( where s is the selection coefficient)

= 1 - 0.2

= 0.8
