Genotypes usually involve some combination of dominant and recessive alleles. What is the most common inheritance pattern?​
mylen [45]

Answer:

The correct answer is option D) six dominant and two recessive.

Explanation:

The most common genetic inheritance pattern involves cross between heterozygous recessive parents which means it has one allele of each character in every parent (suppose Tt).

Cross between these parents provide these offspring; TT, Tt, Tt, and tt which exhibit 3:1 ration which can also be mention as 6:2 which means 6 out of the 8 has dominant (homozygous or heterozygous) and 2 out of 8 offsprings are recessive alleles.

Thus, the correct answer is option D) six dominant and two recessive.

Which of the following statements about eating disorders is false?
tino4ka555 [31]

The correct answer is C. Prevention of eating disorders involves weighing often.

Explanation:

Eating disorders include multiple disorders that involve unhealthy eating habits as well as thoughts and emotions related to them. Individuals who suffer from these disorders constantly worry about their weight and appearance or have an unhealthy relationship with food, for example, individuals with anorexia or bulimia tend to believe they are "fat" even if they had low weight.

Due to this, weighing often is not a way of preventing eating disorders as this behavior just supports an unhealthy obsession with weight and appearance that can lead to eating disorders, instead, a balanced diet should be promoted and risk factors such as depression, anxiety, low self-esteem, etc should be addressed. Thus, the false statement is "Prevention of eating disorders involves weighing often".
