DNA sequences for 10 individuals are

Identify the haplotype carried by each person.

Verified step by step guidance

1. Step 1: Understand the concept of a haplotype. A haplotype is a group of alleles in an organism that are inherited together from a single parent. In this problem, the haplotype is determined by the nucleotide sequence at specific positions in the DNA.
2. Step 2: Identify the variable nucleotide positions in the given sequences. Compare the sequences of all 10 individuals to find positions where the nucleotides differ. For example, examine positions 1, 5, and 10 to see if there are variations.
3. Step 3: Group individuals based on their nucleotide sequences at the variable positions. For example, if position 1 has 'G' in some individuals and 'C' in others, this can help define different haplotypes.
4. Step 4: Assign haplotypes to each individual based on their nucleotide sequence at the variable positions. For instance, if individuals with 'G' at position 1 and 'A' at position 5 share the same sequence at position 10, they may belong to the same haplotype.
5. Step 5: Summarize the haplotypes and list which individuals carry each haplotype. For example, Haplotype 1 might include individuals 1, 4, and 8, while Haplotype 2 might include individuals 2 and 10, based on their shared nucleotide patterns.

Key Concepts

Haplotype

A haplotype is a group of genes or DNA sequences that are inherited together from a single parent. It represents a specific combination of alleles at multiple loci on a chromosome. In the context of the question, identifying the haplotype involves determining the unique sequence variations present in the DNA of each individual, which can provide insights into genetic relationships and ancestry.

Nucleotide Position

Nucleotide position refers to the specific location of a nucleotide within a DNA sequence. Each position is typically numbered sequentially, allowing for easy reference when comparing sequences. In the provided data, the nucleotide positions help identify where variations occur among the individuals, which is crucial for determining their respective haplotypes.

Alleles

Alleles are different versions of a gene that can exist at a specific locus on a chromosome. They can vary in sequence and may result in different traits or characteristics. In the context of the question, analyzing the alleles present at the specified nucleotide positions allows for the identification of the haplotypes carried by each individual, highlighting genetic diversity.
