Explain Mendel's law of independent assortment and how the 9:3:3:1 phenotypic ratio among the F2 of a dihybrid cross provides ev
GrogVix [38]

Answer:

Explanation:

Mendel's law of independent assortment state that two different genes assort independently in gamete formation.

To reach this conclusion, one has to do a dihybrid cross. This means that two genes responsible for different traits need to be analyzed at the same time.

1) Starting with a <u>parental generation of a cross between two pure lines</u> (homozygous for both genes) <u>with different traits</u>, a plant with yellow and round seeds (YYRR) and another with green and wrinkled seeds (yyrr). <u>The F1 will be phenotypically homogeneous (</u>yellow and round)<u>, and genotypically heterozygous (</u><u>YyRr</u><u>)</u>.

2) If the individuals from the F1 are crossed with one another,  we have to do a Punnett Square to determine the phenotypic ratio of the F2.

  • If the genes assort independently, the F1 individuals will produce their different gametes with the same probability. Each possible gamete will appear in a 1/4 proportion: YR, Yr, yR, yr.
  • The 9:3:3:1 ratio is a result of analyzing the possible phenotypes that result from the dihybrid cross.

See the attached image for an illustration of the crosses in each generation and the Punnett Square.

TRNA molecules deliver amino acids to ribosomes where the amino acid next
lesantik [10]

Answer:

tRNA molecules deliver amino acids to ribosomes where the amino acid next becomes an anticodon (option C).

Explanation:

A tRNA molecule is able to deliver amino acids to the ribosomes for protein synthesis, forming an anticodon that complements the codon of the mRNA being translated. The mRNA molecules are responsible for conducting the genetic code —obtained from DNA transcription— to be translated by the ribosomes. This code is established by sequences of three nucleotides, called codons, which encode different amino acids.

What happens when mRNA molecules expose codons to ribosomes is that a tRNA molecule containing a complementary anticodon is formed, which is conducted to the ribosome to bind to the codon. This allows, according to the genetic code, the formation of a protein with a specific sequence of amino acids.

Charra [1.4K]

Answer:

True:

"Stepping stones" are a type of corridor.

Explanation:

True, three types of the corridor can connect habitat clusters. The first one is called linear corridor and alludes to the line because it is a line. The second type of corridor is the landscape corridor which is a link of big sets of the material linked one to the other without a geometrical figure but creating a firm path. And finally, stepping stones corridors are composed of separated step stones that always keep distance one from the other.
