Marina86 [1]

Answer:

Ribosomal RNA (rRNA) associates with a set of proteins to form ribosomes. These complex structures, which physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains. They also bind tRNAs and various accessory molecules necessary for protein synthesis.

Turtles and leopards all have four limbs and an amnion. True The common ancestor of lamprey and lancelets had a vertebral column

kramer

Answer:

Explanation:

The objective is to conclude if the statements are true or false based on facts.

1) $\text{ Turtles and leopards all have four limbs and an amnion. }$ True

2) $\text{The common ancestor of lamprey and lancelets had a vertebral column. }$ False

This is because their ancestor is a Chordate who doesn't have a vertebral column but a notochord.

3) True

$\text{Frogs are the sister taxa of turtles and leopards because they are more }$

$\text{related to a common ancestor.}$

4) $\text{Leopards and bass are more closely related than turtles and bass}$ False

This is because the bass is a fish that possess some characteristics traits related to an amphibian (turtle) as compared to a mammal(leopard).

5) $\text{The taxon that shares the most recent common ancestor with frogs is the bass.}$ False

The taxa of turtles share a more common ancestor with frogs compared to bass.

6) $\text{Leopards and lancelets have no common ancestor. }$ False

The common distant ancestor for leopards and lancelets is known as Chordates

Two independently segregating genes determine kernel color in wheat. Red color results from at least one dominant allele in both

Lera25 [3.4K]

Answer:

a) The expected phenotype of the F1 plants is 100% RrBb, red kernels.

b) The expected phenotypic classes in the F2 are: 9:3:3:1

9/16 R-B-, 3/16 rrB-, 3/16 R-bb, 1/16 rrbb

Proportions 9:6:1.

9/16 Red kernel (R-B-), 6/16 Brown kernel (rrB- + R-bb), 1/16 White kernel (rrbb)

Explanation:

Available data:

red kernel: R-B-

brown kernel: R-bb or rrB-

white kernel: rrbb

1º Cross) RRBB x rrbb

F1) 100% RrBb (red kernels)

2ºCross) RrBb x RrBb

Gametes) RB RB

Rb Rb

rB rB

rb rb

Punnet Square) RB Rb rB rb

RB RRBB RRBb RrBB RrBb

Rb RRBb RRbb RrBB Rrbb

rB RrBB RrBb rrBB rrBb

rb RrBb Rrbb rrBb rrbb

F2) Phenotypic classes:

9/16 R-B-

 3/16 rrB-

 3/16 R-bb

 1/16 rrbb

Phenotypic proportions:

9/16 Red kernel (R-B-)

6/16 Brown kernel (rrB- + R-bb)

1/16 White kernel (rrbb)
