<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:
Humans are most highly evolved and most complex animals
Answer:
Las hormonas controlan las diferentes enzimas digestivas que se secretan en el estómago y el intestino durante el proceso de digestión y absorción. Por ejemplo, la hormona gastrina estimula la secreción de ácido del estómago en respuesta a la ingesta de alimentos. La hormona somatostatina detiene la liberación de ácido del estómago.
Explanation:
A series of radiographic images taken of the stomach and duodenum after the contrast agent barium has been swallowed is an upper GI series, where
GI<span> stands for "</span>gastrointestinal<span>," which means "stomach and intestines".
</span>This x-ray examination of the upper gastrointestinal<span> (</span>GI<span>) tract,</span>can diagnose problems in your upper GI tract, how to prepare for the procedure, and what to expect afterwards.
