Answer:
1. A locatable region of genomic sequence, corresponding to a unit of inheritance which is associated with regulatory regions, transcribed regions, and/or other functional sequence regions.
2. Were historically defined as the unit of hereditary material that causes a phenotype.
3. May be composed of a union of genomic sequences encoding a coherent set of potentially overlapping functional products.
Explanation:
A gene is a sequence of nucleotide present on a chromosome which determines a trait of an organism. The gene term was provided by the Wilhelm Johannsen in 1909 to refer to the hereditary unit of the organisms.
The genes in eukaryotes are not necessary that they will code for the protein as there are some RNA molecules which are not translated into the protein like rRNA and tRNA molecules.
The sequence of a gene in eukaryotes is a union of the regulatory of the functional and transcribed genes.
Thus, the selected option is correct.
Answer:
excretory system
Explanation:
The excretory system is the system of an organism's body that performs the function of excretion, the bodily process of discharging wastes. ... There are several parts of the body that are involved in this process, such as sweat glands, the liver, the lungs and the kidney system. Every human has two kidneys.
Answer:
AaBb
Explanation:
In the given dihybrid cross, the genotype of one parent plant is AABB and that of the other parent plant is aabb. The parent plant with the "AABB" genotype would form all the gametes having "AB" alleles. The parent plant with "aabb" genotype would form all the gametes having "ab" alleles. The random fusion of the gametes from the two parents would produce all the progeny of F1 having the genotype "AaBb".
Therefore, the F1 generation would be heterozygous dominant for both the genes under study.
Cross: AABB x aabb= AaBb
