So no one gets hurt or harmed when the go off
*this is based on the assumption that parent two is homo_zygous dominant.
If a hetero_zygous and a homo_zygous dominant parent are crossed:
Genotypic Ratio
WW: Ww
1 : 1
Phenotypic Ratio
white : purple
[1 : 0] or [100% : 0%]
100 will have a white colour while 0 will have a purple colour.
Answer: The tuatara is a lizard-like reptile found only in New Zealand today, the last surviving lineage of a large group of reptiles that were contemporaries of the dinosaurs.
The traits that would i expect the <u>tuatara</u> to possess are:
- Spiny back similar to that of dinosaurs.
- A well developed pineal eye.
- It lacks a copulatory organ.
- Spine-like vertebrae with intercenters.
- Anterior teeth, large and very sharp.
Explanation:
<u>Living fossil</u> is an expression used to qualify non-extinct species that are extremely similar to species identified only through fossils.
A <em>pineal eye</em> is a part of the epithalamus present in some animal species. The eye can be a photoreceptor and is commonly associated with the pineal gland, regulating the circadian rhythm and hormonal production for thermoregulation. The tuatara has a developed parietal eye, <u>with retina and lens.</u>
The correct option is B.
The field of science is very dynamic and it thrives on discovery of new evidences. When new evidence are found for a particular phenomenon, the existing phenomenon has to be adjusted to fit the new discovery. Air pollution was once named to be responsible for global cooling because enough evidence was not available then to prove otherwise but now overwhelming evidences show that pollution is responsible for global warming.<span />
