They are basically the next step up from atoms. They are smaller living organisms. (might not be helpful but it's a start)
Mitosis<span> plays an </span>important<span> part in the life cycle of most living things, though to varying extents. In unicellular </span>organisms<span> such as bacteria, </span>mitosis<span> is a type of asexual reproduction, making identical copies of a single cell. In </span>multi-cellular organisms<span>, </span>mitosis<span> produces more cells for growth and repair.</span>
If an individual were heterogeneous then there would be a 50/50 chance of being either dominant or recessive. I hope this helps. :)
<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%).
