In humans, if a non-disjunction event led to an individual with a genotype of xxy, they would.
k0ka [10]

In humans, if a non-disjunction event led to an individual with a genotype of XXY, they would be male because they have a Y chromosome.

<h3>What are X and Y chromosomes?</h3>

The X chromosome and Y chromosome are homo-logous chromosomes that determine the se_x in mammals.

The presence of the Y chromosome is indicative of the males, whereas two X chromosomes are females in normal conditions.

Non-disjuntion refers to the faulty separation of homo-logous chromosomes during meiosis.

Which of the following minerals will NOT scratch glass?
Shtirlitz [24]
The answer is fluorite. If a mineral cannot be scratched by a knife blade but can be scratched by quartz then its hardness is between 5 and 7 on mohs scale. A relative hardness value of 6.5 means that the mineral could scratch orthoclase but not quartz. Flourite hardness on mohs scale is 4, and therefore due to the very low hardness and perfect cleavage of Flourite, special care must be taken to ensure it doesn't get scratched or chipped. It cannot scratch the glass.

Lunna [17]

Answer:

New mutations will become permanent

Explanation:

Human MutL homolog 1 (MLH1) gene is a well-known tumor suppressor gene that encodes for a DNA mismatch repair protein. The MLH1 protein is part of the DNA mismatch repair (MMR) genetic system which recognizes and repairs the incorrect addition of nucleotides during DNA replication and recombination. It has been shown that inherited mutations in one allele of the MLH1 gene increase the risk of cancer, especially colorectal cancer.
