Complete question:
In man, two abnormal conditions, cataracts (C) in the eyes and excessive fragility (F) in the bones, seem to depend on separate dominant genes located on different chromosomes. Normal vision and normal bones are recessive traits. A man with cataracts and normal bones, whose father had normal eyes, married a woman free from cataracts but with fragile bones. Her father had normal bones.
1. What is the genotype of the man with cataracts and normal bones?
2. What is the genotype of the woman with normal vision and fragile bones?
3. What type of offspring might this couple expect?
Answer:
- Cc ff
- cc Ff
- F1) 4/16 = 1/2 = 25% CcFf, cataracts and fragile bones
4/16 = 1/2 = 25% Ccff, cataracts and normal bones
4/16 = 1/2 = 25% ccFf, normal eyes and fragile bones
4/16 = 1/2 = 25% ccff normal eyes, normal bones

Answer:
The carbon dioxide is one of the green house gases and mainly responsible for the increase of the earth's temperature. The plants uses the carbon dioxide for the photosynthesis process.
The plants that are exposed to the normal carbon dioxide can be used as a control in this experiment. Then the scientists will notice that if the amount of carbon dioxide is increased, does it show any positive or negative effects in the experiment.
Answer: a niche is a role that an organism plays in an environment. If you want a dictionary definition, here it is.
Explanation:
a position or role taken by a kind of organism within its community. Such a position may be occupied by different organisms in different localities, e.g., antelopes in Africa and kangaroos in Australia
Answer:
One of the probable ways to determine how long ago any two species of bacteria diverged from each other is by drawing a phylogenetic tree.
Explanation:
- Phylogenetic tree are trees that show the ancestry of two species of interest and the relationship between them.
- The idea behind the construction of phylogenetic tree is darwins's "descent with modification theory".
- A phylogenetic tree is constructed using the similarities or differences in either physical characteristics, behavorial, or genetic buildup.
- Derived traits shared between the different species are the actual data used to construct a phylogenetic tree.
Stationary front. a front that does not move or barely moves.
