Answer:
DNA does not support the hypothesis that coelacanth is the closest relative to amphibians.
Explanation:
After several DNA analyzes, including analysis of mitochondrial DNA sequences, scientists found that coelacanth DNA does not support the idea that it is the closest relative of amphibians. However, other molecular analyzes, looking at the DNA of other living beings, concluded that the pulmonary fish is, in fact, the closest relative of the amphibians, with Coelacanth being the closest relative of the tetrapods.

The feature hair type is coded by a diallelic gene and expresses incomplete dominance. The cross of two wavy haired individuals will produce 25% curly-haired children, 50% wavy-haired and 25% straight-haired children.
<h3>
What is a Punnett square?</h3>
The Punnett square is a cross representation that shows all possible combinations between the parental gametes.
It shows the probabilities of getting offspring with different genotypes and their consequent phenotypes.
Let us say that we are analyzing the feature hair type.
Hair type is coded by a diallelic gene that expresses incomplete dominance.
- The dominant allele C codes for curly
- The recessive allele c codes for straight hair
- The combination of both alleles in heter0zyg0us state codes for wavy hair.
Let us say that both parents have wavy hair.
Cross:
Parentals) Cc x Cc
Gametes) C c C c
Punnett square) C c
C CC Cc
c Cc cc
F1)
<u>Genotype</u>:
1/4 = 25% of the progeny will be h0mzyg0us dominant, CC.
2/4 = 1/2 = 50% of the progeny will be heter0zyg0us, Cc.
1/4 = 25% of the progeny is expected to be h0m0zyg0us recessive, cc.
<u>Phenotype</u>
1/4 = 25% of the progeny will have curly hair (CC).
2/4 = 1/2 = 50% of the progeny will have wavy hair (Cc).
1/4 = 25% of the progeny is expected to have straight hair (cc).

Answer:
Before meiosis actually begins, the DNA that is packaged into chromosomes must be fully copied.
