The genetic code consists of ____________ letter “words.”
san4es73 [151]

Answer:

The genetic code consists of <u>three</u> letter “words.”

Explanation:

I'm assuming this was what you're looking for. These "words" are known as codons: for example, AUG stands for the methionine amino acid, so that triplet of nucleotide bases leads to the Met amino acid being added to the final protein.

In chickens, having feathers on legs is dominant to having featherless legs. In a population of 200 chickens, 128 have featherle
Neporo4naja [7]

Answer:

64

Explanation:

Since the population is in Hardy-Weinberg equilibrium and the equilibrium is defined by the equation

p² + 2pq + q²

where the frequency of the homozygous dominant allele F ( feathers on the leg ) = p²,

F of homozygous ( featherless legs) = q²

F of heterogyous ( carrier of featherless allele) = 2pq

F (q²) = 128/200 = 0.64

q = √0.64 = 0.8

and p + q = 1

p = 1 - 0.8 = 0.2

2pq = 2 × 0.2 × 0.8 = 0.32

number of chickens that are heterozgous for the feathered leg allele = 0.32 × 200 = 64

Lancelets and coelacanths are more closely related than are chimaeras and coelacanths.

Organism (a) is a common ancestor of all chordates.

Descendants of organism (d) have limbs with digits. birds and ray-finned fishes have a notochord and jaws.

rays and frogs have vertebrae. organism (c) is a common ancestor of lampreys and lungfishes?

The correct options are;

Mammals and turtles are more closely related than are lungfishes and sharks.

Descendants of organism (d) have legs.

Rays and frogs have a vertebral column.

-Birds and ray-finned fishes have a notochord and jaws

Explanation:

This is because phylogenetic tree is a branching diagram that entails different evolutionary relationships that occur between organisms or biological species having common decent or ancestors and showing similar and differences in their genetic characteristics or traits. It shows how species evolved from their ancestors.
