A woman with a straight hairline has as child with a man who is heterozygous
and has a widow's peak.
What is the mother's genotype?

Answer:

aa

Explanation:

A widow's peak is the dominant genotype so one must not have that trait. If it was presented then the woman would have the genotype.

A widow's peak is dominant so the man would be either AA or Aa. Since it stated that his is heterozygous (Hetero meaning two different), his genotype would be Aa (again since a widow's peak is the dominant, it only needs one dominant genotype)

What types of mutations are the most harmful

The gene for nose shape is found on the X chromosome. Round nose is dominant to pointed nose. Human individuals with XXY (an additional X chromosome) are designated male. Individuals with XO (only one X chromosome) are designated female. Identify the possible nondisjunction events (rare mistakes during meiosis) that could explain the phenotype of the offspring. An XY parent with a round nose and a XX parent with a round nose have an offspring with Klinefelter Syndrome (genotype XXY) with a pointed nose.

Anthropologists have been studying the role of soybean curd andrelated products in the culture of Hong Kong. The researchers interviewpeople about how frequently they eat soybean products, where they eatthem (at home or in restaurants), and during what time of day they eatthem. The researchers also ask people about how they preparesoybean products, where they obtain soybean products, and any beliefsthey might have about soybean products (such as their nutritionalvalue). The data are used to assess the role of soybean products in theculture. The researchers are also considering how their findings relateto global soybean consumption patterns.

What is poisonous enough to kill 100,000 turkeys? That’s the question asked by scientists who studied a mass die-off of turkeys in Great Britain. It turned out that all the turkeys had eaten peanuts from Brazil. A fungus was growing on the peanuts. The fungus produced a dangerous poison called aflatoxin. Aflatoxins cause stomach pain, lung failure, cancer, and death in people and animals.

Farmers make a great effort to prevent fungi from growing on their stored crops. In a pile of grain or nuts, fungi have plenty of food and living space. The best way for farmers to prevent fungi from growing is to make sure there is not enough for fungi to survive and grow.
