Dominate animals hunt the smaller and weaker animals for survival.
Question in English:
A female carries a recessive lethal gene (l) on one of her X chromosomes, and a normal dominant allele (L) on the other. What is the sex ratio to be expected in this woman's dependency if she marries a normal man?
Answer:
2/3 females
1/3 males
Explanation:
Females have two X chromosomes (XX) and males have an X and a Y chromosome (XY).
The genotype of the female is XLXl. The genotype of the male is XLY, since he is normal.
The possible genotypes are:
<u> XL Xl</u>
<u>XL</u> <em>XLXL XLXl</em>
<u>Y</u> <em>XLY </em><em>XlY</em>
<em />
All female offspring will be normal as they will always have one normal copy of the X chromosome from their father.
50% of the male offspring will be normal, but 50% will inherit the lethal gene from their mother.
Because the allele is lethal, that means XlY males will not be born.
That means 2/3 of the children will be females, and 1/3 will be males.
Answer:
The forensic autopsy is preformed by "Forensic pathologist".
Explanation:
The forensic pathologist would perform a forensic autopsy, Forensic pathologist will focus on the cause behind the death by studying the body or the corpse.

The forensic pathologist are basically there to find the cause and also the manner of death. They are trained for performing autopsy, helps in evaluation of historical and law enforcement investigative information, documentation in sexual assault, helps in collection of the medical evidence.
Answer:
Crossing over is termed as a process by which genetic materials are exchanged by non-sister chromatids during meiosis. Crossing over results in the new combination of information in genetic for, the cell for a specific trait. It ensures that organisms are identical from one generation to another.
