There are two types of toxins; endotoxins and exotoxins. ... On the other hand, endotoxins are less lethal but can cause fever to the host. Exotoxins are secreted by bacteria and release outside the cell whereas endotoxins are bacterial toxins located within the cells.
<span>F- allele for freckles
f- </span><span>allele without freckles
1) The man is heterozygote and has freckles, its indicating that the allele for freckles is dominant.
A cross between him and a woman who is also </span><span>heterozygote: Ff x Ff
it would result in the following probabilities:
- 1/4 - homozygote with freckles: FF
- 2/4 - </span><span>heterozygote with freckles: Ff
- 1/4- </span><span>homozygote without freckles:ff
Their son would have a probability of 75% of being born with freckles.
2) The cross resulted in this probabilities:
</span><span><span>- 1/4 - homozygote with freckles: FF
- 2/4 - </span><span>heterozygote with freckles: Ff
- 1/4- </span><span>homozygote without freckles:ff
So, the chance of being born heterozygote for this gene is 2/4, which is the same as half (50%).

<span>Aquatic organisms and the physical and chemical components of their environment are inseparably inter-related and interact with other. Flow and water chemistry are the primary factors governing life in riverine habitats, and both are closely related to seasonal variations.</span>
Abiotic is the non living organisms and biotic is the living organisms.
