<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%).

Answer:
<h2>Source of Light in Universe</h2>
<h3>Although the Sun doesn't light up the other stars, it does provide the daylight here on Earth; and the moon and planets we see are illuminated by that same sunlight. All stars produce light (and other kinds of energy) through nuclear reactions, using the energy stored in the tiny nucleus at the center of atoms.</h3>

B. liquid! Becuase its Seperational atoms have a Huge Attraction within Heated Atoms..from the Sunlight It then sweats..It starts too Evaperate then later by time it Rains.. Etc "Water Cycle" correct me if im Wrong..
<span>Stem cells are found in multicellular organism,they are undifferentiated in nature and can form other special cells or could divide in further stem cells by mitosis.The person with brain or spinal cord injury would be interested cause these cells could be used in future to cure the problem.Human embryonic stem cell (HESC) research is ethically and politically controversial because it involves the destruction of human embryos.The resource used was paper by B Lo named 'Ethical Issues in Stem Cell Research'.And according to me research in this field is important for development of mankind</span>
