Question 1

Regarding non-Mendelian genetics, which statement accurately describes continuous variation?

Answer 1

The greater the genes that influence a character the more continuous the expected distribution

Question 2

Regarding non-Mendelian genetics, which statement describes an example of continuous variation discussed in class?

Answer 2

If you are in a family with a lot of tall people, you’ll likely be tall because there’s not a lot of short genetics

Question 3

Regarding non-Mendelian genetics, which statement accurately describes pleiotropic effects?

Answer 3

An individual allele has more than 1 effect on the phenotype

Question 4

Regarding non-Mendelian genetics, which statement describes an example of pleiotropic effects discussed in class?

Answer 4

Sickle-Cell disease

Question 5

Regarding non-Mendelian genetics, which statement accurately describes incomplete dominance?

Answer 5

Not all alternative alleles are fully dominant or fully recessive in heterozygotes

Question 6

Regarding non-Mendelian genetics, which statement describes an example of incomplete dominance discussed in class?

Answer 6

You can have a red flower, pink flower or white flower, it is not just 1 or the other

Question 7

Regarding non-Mendelian genetics, which statement accurately describes environmental effects affecting genetic expression?

Answer 7

The degree to which an allele is expressed depends on the environment

Question 8

Regarding non-Mendelian genetics, which statement describes an example of environmental effects affecting genetic expression discussed in class?

Answer 8

Arctic fox is white in the winter and darker colors in other seasons

Question 9

Regarding non-Mendelian genetics, which statement accurately describes epistasis?

Answer 9

One gene interferes with the expression of another

Question 10

Carl Correns (1900) and Walter Sutton (1902) were two scientists who contributed to the discovery of the chromosomal theory of inheritance. Which statement describes this theory?

Answer 10

Idea that if you have a somatic cell it’s going to have two sets of chromosomes, gametes will have one set of chromosomes

Question 11

Carl Correns’s (1900) and Walter Sutton’s (1902) work led to the chromosomal theory of inheritance. Which of these statements describe this theory?

Answer 11

Idea that if you have a somatic cell it’s going to have two sets of chromosomes, gametes will have one set of chromosomes
