I think it is D
Hope this help you??
Answer:
The population is not following the Hardy-Weinberg equilibrium.
Explanation:
Hardy-Weinberg proposed that the population will remain in the equilibrium if they are not affected with the external natural force like genetic drift, mutation and many others. The gene pool of a population will remain in equilibrium state for generations.
The mathematical expression for the Hardy-Weinberg are
Genotypic frequency is p²+q²+2pq=1
Allele frequency is p+q=1
where p-dominant allele,
q-recessive allele
Therefore,calculating expected frequency of allele q,
q² (recessive genotype)- q²+2pq/1000
= 22+188/1000
=210/1000
= 0.21
q= 0.45
Calculating expected frequency of allele p,
Using p+q=1
p=1-q
p= 0.55 (expected)
Calculating observed value of frequency of p,
p²= p²+2pq/1000
= 790+188/1000
= 978/1000
= 0.978
p = 0.988 (observed)
Since the expected frequency does not match the observed frequency therefore the population is not under the Hardy-Weinberg equilibrium and the gene pool is disturbed.
Answer:
endosymbiosis.
Explanation:
By the beginning of the 20th century, researchers thought that plastids and mitochondria could come from bacteria. These would have been ingested by primitive cells and live within them in symbiosis.
Answer:
I'm not sure, but I think it's B
Explanation:
Condensation's is the conversion of a vapor or gas to a liquid, so I think it's B
1) The correct answer is: 128 combinations.
The genetic combinations that are possible through independent assortment can be calculated as 2^n; where n is the number of different chromosomes.
So, using this formula for 7 chromosomes:
2^7 = 128 different combinations.
2) For a zygote produced by two barley parents, the number of possible genetic combinations can be calculated as: 2^n * 2^n
So, for 7 chromosomes: 2^7 * 2^7=16384
