Answer #1

1)it is caused by abnormality in X- linked gene on x chromosome. Both male and females are equally effected because in both x chromosome is present. in this syndrome the body can't make enough protein required for brain growth and development.

2) A test used to determine the mutagenic activity of chemicals.it is used to detect that any chemical is carcinogenic or not and where the chemical cause mutation in DNA of test organism.

3) It code for a protein which regulate cell cycle. it is important in multicellular organism to suppress cancer.

4) it is a hereditary disorder characterized by short ,brittle hair with low sulphur content (sulphur deficient hair).

You are studying disease X, a genetic disorder that arises from a trinucleotide repeat expansion mutation which is a mutation where entire codons are multiplied during the replication process. The mutation is found in the CaM gene, that is a 450-base pair (bp) sequence. The trinucleotide repeat expansion results in the addition of 10 codons (30 bp) at nucleotide 150 (ie in the centre of the gene, away from the 5’ and 3’ end). The sequence of the normal gene...

Please show WORK! In some horses, coat color is autosomal and exhibits incomplete dominance, with palamino coloration intermediate to both chestnut and cremello coloration. Horses can also exhibit an immunodeficiency syndrome inherited as an X-linked recessive allele. You are a horse breeder, and cross a palamino female carrier for immunodeficiency syndrome with a normal, cremello male. 1. Use appropriate genetic notation to describe genotypes of the cross. 2. If you conducted this cross many times, what would be the expected...
