BigorU [14]

Answer:

b

Explanation:

<em>Let the wild type trait, the silver-white, be represented by </em><em>A</em><em> allele and the mutant trait, the golden color, be represented by </em><em>a</em><em> allele.</em>

Heterozygous wild-type male fish would be Aa

Golden female fish would be aa

Aa x aa

Aa Aa aa aa

2/4 Aa = silver-white

2/4 aa = golden color

<em>Hence, the percent likelihood of golden offspring is </em><em>2/4 or 50%.</em>

The correct option is b.

Answer:

Collagen genes.

Explanation:

Phylogenetics helps to study the evolutionary relationship among the different group of organisms. The different characteristics like DNA sequences, mitochondria sequences can be used for the construction of phylogeny tree.

Collagen genes can be used to study the evolutionary relationship as mammals contains nearly 30% of total protein. The collagen gene shows the most of the conserved sequences among the different group of organisms and shows the most recent evolved characters in vertebrates.

Thus, the correct answer is collagen genes.
