Answer:
Approximately 20,500 genes
Explanation:
The Human Genome Project (HGP) was a 13-year international research effort aimed at determining the entire DNA sequence of the human genome. The HGP was launched in 1990 and completed in April 2013. This project helped to identify and physically map all the genes of the human genome. The sequence obtained from the HGP has been a very useful point of reference in order to identify and characterize mutations associated with genetic disorders. The HGP predicted approximately 20,500 genes (each of them produces an average of three proteins), which are distributed in the 23 pairs of chromosomes in the cells of our body.
Answer:
Explanation:
If the disorder is recessive, neither parent has to have the disorder because
they can be heterozygous. The characteristic features of autosomal recessive inheritance is as follows:-
•Appears in both sexes with equal frequency
• Trait tend to skip generations
• Affected offspring are usually born to unaffected parents
• When both parents are heterozygous approx. 1/4 of the progeny will be affected
• Appears more frequently among the children of consanguineous marriages.
The given pedigree follows these features. So the correct option is 'Autosomal recessive trait'.
Please correct me If I am wrong :)
