Answer:
Random segregation of homologous chromosomes makes the two siblings differ from each other for 0-23 chromosomes.
Explanation:
Sexual reproduction adds genetic variations in the progeny by crossing over, independent segregation of homologous chromosomes and random fusion of gametes. Without crossing over, independent segregation of homologous chromosomes towards opposite poles during anaphase I of meiosis may result in two siblings to vary from each other for 0-23 chromosomes.
There is an equal probability of each of the two siblings to get a chromosome from mother or father. Hence, irrespective of the variations provided by crossing over, random segregation of homologous chromosomes makes the two siblings differ from each other for 0-23 chromosomes.
D habitats because it is divided up into different areas and different areas have different kinds of habitats
Answer: 1. B-D-A-C.
Explanation: If a genetic error occurs during chromosome replication, it will lead to a series of events ranging from:
1) Production of a DNA strand with an altered base sequence.
2) Production of an mRNA strand with an altered base sequence during transcription. This is because mRNA is synthesized by copying the genetic message coded in the DNA.
3). Synthesis of a protein with an altered amino acid sequence during translation, and this eventually leads to
4). The expression of a new inheritable trait in the organism.
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person's body has the same DNA
DNA sequencing refers to the general laboratory technique for determining the exact sequence of nucleotides, or bases, in a DNA molecule
