Cladograms (a type of phylogenetic tree) constructed from evidence from molecular systematics are based on similarities in

Biology
1 answer:
defon3 years ago
5 0

Answer:

The correct answer is "mutations to homologous genes".

Explanation:

The missing options of this question are:

A) morphology.

B) the pattern of embryological development.

C) biochemical pathways.

D) habitat and lifestyle choices.

E) mutations to homologous genes.

The correct answer is option E) "mutations to homologous genes".

Modern cladograms do not use physical characteristics to establish evolutionary similarities among species. Modern cladograms are constructed from evidence from molecular systematics based on similarities in mutations to homologous genes. The more similar are the homologous genes, the less different their genetic sequences are, and are considered more closely related in their evolutionary tree.

Black coat color in horses is conferred by the presence of a dominant B allele. Chestnut horses are genotype bb. A population of
AysviL [449]

Answer:

Frequency of B allele is 0.6681

Explanation:

If p represents the frequency of dominant allele and q represents the frequency of  recessive allele, according to Hardy-Weinberg equilibrium:

p + q = 1

p² + 2pq + q² = 1

where p² = frequency of homozygous dominant genotype

q² = frequency of homozygous recessive genotype

2pq = frequency of heterozygous genotype

Given that number of recessive chestnut horse = 28

Total horses = 226 + 28 = 254

frequency of b² genotype = 28/254 = 0.1102

frequency of recessive b allele = √0.1102 = 0.3319

So, frequency of B allele =

1 - 0.3319 = 0.6681

Hence frequency of B allele is 0.6681

Which sentence best describes the relationship between genes and chromosomes?
Maurinko [17]

Answer:

A. Genes are found within chromosomes.

Explanation:

A chromosome is a single linear, coiled DNA molecule that contains part or even all the genetic material of an individual. On the other hand, genes are chromosomal segments that contain the instructions required to encode a specific protein, which is stored in the form of a sequence of nucleotides. In consequence, a chromosome may have many genes. In biology, a gene is considered to be the basic physical and functional unit of heredity.
