3) easy to grow, can be shown year, used for similar studies
4) we are the parents produce offspring that would carry the same phenotype
5) he removed the anthers from the flowers
6) a trait or character is a feature of an organism.
7) the basic physical and functional unit of heredity
8) one of the possible forms of a gene
9) the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction.
10) “P” for parental generation.
11) F1 generation refers to the first filial generation
12) F2 second filial generation consists of the offspring from allowing the F1 individuals
13) The dominant allele is the one that gets expressed.The recessive allele is still there, it just isnt shown.

Answer is A
Answer:
The best explanation for the increased lymphocyte levels in Kaya is that she was not tissue typed prior to her surgery, and her body is mounting an immune response.
Explanation:
When performing an organ transplant, it must be verified whether the organ to be transplanted is compatible -by tissue typing- with the recipient, since it is recognized as a foreign body by the body and can be rejected.
One of the immunological responses to organ rejection is called cell rejection, involving T-helper and cytotoxic lymphocytes.
<u>It is very likely that in Kaya's case the tests have not been performed correctly, and she is experiencing rejection of the organ she received</u>. The progressive increase in lymphocytes may be an indication of this.
The other options are not possible because:
- <em>Administering </em><u><em>antibiotics</em></u><em> should not raise lymphocyte levels.
</em>
- <em>There is no evidence of </em><u><em>antigen </em></u><em>attack.
</em>
- <u><em>Immunosuppressant drugs</em></u><em> do not increase lymphocyte count.</em>
Answer:
D - Its genetic diversity is very low
Explanation:
An extinction vortex can be defined as the process which populations in decline pass through to drive them into a vortex of smaller populations, endangering their survival as they tread the path to extinction.
Populations that fall to extinction vortex already have small populations which is usually as a result of certain powerful genetic factors, which cause the populations to continue to decline in size.
During genetic drift which occurs in all populations, small populations tend to lose genetic diversity as a result of the random nature of gamete sampling.
This is because any change in alleles in a small populations can have dastardly effects on the populations size due to a small gene pool.
