If its outermost electron shell is filled.
In an individual heterozygous for a single trait, the probability of the recessive allele being present in a gamete is 50 percent.
<h3>What is an Allele?</h3>
This can be referred as the variant form of a gene. In an individual heterozygous for a single trait there is the presence of the dominant and recessive allele present in the gamete.
This however means that the probability of the recessive allele will be 1/2 which is equal to 50 percent.

Answer: The electrons in an atom that take part in chemical bonding are the electrons in the outermost shell and they are called valence electrons.
Explanation: An atom is composed of three particles: protons, neutrons and electrons. The protons and neutrons occupy the centrally located nucleus while the electrons are located in the empty space outside the nucleus. Electrons are distributed around the nucleus in paths called electron shells. The electrons in the outermost electron shells are called the valence electrons. The valence electrons are the electrons that participate in chemical bonding. During chemical bonding, the valence electrons are either transferred from one atom to another or the valence electrons are shared between two atoms. A type of chemical bonding in which there is a complete transfer of valence electrons from an atom of a metal to an atom of a non-metal so that can attain octet or duplet structure of noble gases is called electrovalent or ionic bonding. A type of chemical bonding in which there is sharing of electrons between two atoms of non-metals so that both can attain the octet or duplet structure of noble gases is called covalent bonding.
Answer:
Alveoli are tiny, balloon-shaped air sacs. Their job is to move oxygen and carbon dioxide (CO2) molecules into and out of your bloodstream.
