Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive.
Answer:
Black
Explanation:
When the room lights are turned off any object present in the room appears black.
<h3><u>Answer and explanation;</u></h3>
- This can be done by<u> DNA sequencing which is the process of determining the accurate order of nucleotides within a DNA molecule</u>.
- By doing a DNA sequencing for the two sequences of DNA from the two species it will help compare the number of random mutations which have occurred in a molecular clock in the two species - that is, seeing how different the sequences are.
- This will make it possible to infer how long ago the species diverged.
Species A: GTTGAGCTAGTATGGACC
Species B: GATAAGCTAGTAAGGTCA
These species differ in 5 nucleotides.
This number should be multiplied by the rate of mutations; that is;
5 × 15 million years =75 million years.
