Answer:
Allele is the form in which sequenced information within a single gene can be expressed. One allele is paired with another within a gene, which is part of a chromosome and which determines the expression of specific traits.
Explanation:
The genetic information is contained in the DNA, and each molecule of this nucleic acid forms a chromosome containing genes, fragments of the DNA of the chromosome with a sequence of nucleotides for the synthesis of specific proteins.
Genes determine morphological or functional features of a living being. Each gene contains two alleles for each trait it determines, the alleles being different sequences of nucleotides that constitute different ways in which a trait can be expressed.
<h3>How are the alleles related to genes, chromosomes and traits?
</h3>
Each gene contains two alleles, either the same or different, with the sequence of nitrogenous bases to determine the possible ways in which a trait is expressed. The different sequences of the alleles can produce specific modifications of the function of that gene, conditioning the different forms of expression of a trait.
Genes, which contain alleles, are found within a chromosome, at a specific location called a locus.
Answer: Haploid cells have 23 chromosomes while diploid cells have 46 (23 pairs) chromosomes
Explanation: Haploid cells are produced in a type of cell division called meiosis. In meiosis, parent cells undergo two cell divisions to produce four daughter cells with half the number of chromosomes in the parent cell. Diploid cells are produced by a type of cell division known as mitosis. In mitosis, parent cells undergo one cell division to produce two identical daughter cells that have the same number of chromosomes as the parent cell. Gametes undergo meiosis while somatic cells undergo mitosis.
Answer:
the characteristic of vertebrates from the following is
Answer:
B. They are considered stable over a lifetime
Explanation:
The only statement that is not true concerning the definition of life in general is that "They are stable over time." This can be proven in the early years of earth's life wherein different microorganism and macroorganism lives. Over time, they evolved into another species that is most suitable to the kind of envionment the earth is evolving.
