[QUESTION]Based on this information, what is this plant's phenotype for the growth pattern trait?
[OPTIONS](A) bush growth (B) climbing growth
bush growth
The rose plant's genotype for the growth pattern gene is gg. The rose plant's genotype of gg has only g alleles. The g allele is for bush growth. So, the rose plant's phenotype for the growth pattern trait must be bush growth. To check this answer, consider whether the rose plant's alleles are dominant or recessive. The allele for bush growth (g) is recessive to the allele for climbing growth (G). This means G is a dominant allele, and g is a recessive allele. The rose plant's genotype of gg has only recessive alleles. An organism with only recessive alleles for a gene will have the recessive allele's version of the trait. So, the rose plant's phenotype for the growth pattern trait must be bush growth.

[QUESTION]Which statement best describes the average monthly precipitation in New Orleans?
[OPTIONS](A) The wettest months of the year are June, July, and August. (B) October is the wettest month. (C) February is wetter than June.
The wettest months of the year are June, July, and August.
To describe the average precipitation trends in New Orleans, look at the graph. Choice "Feb" is incorrect. Choice "Jun" is incorrect. Choice "Jul" is incorrect. Choice "Aug" is incorrect. Choice "Oct" is incorrect. Choice "The wettest months of the year are June, July, and August." is incorrect. On average, more precipitation falls during June, July, and August than during other months of the year. So, June, July, and August are the wettest months. Choice "February is wetter than June." is incorrect. February has a lower average precipitation than June. So, February is drier, not wetter, than June. Choice "October is the wettest month." is incorrect. Every other month has a higher average precipitation than October. So, October is the driest, not the wettest, month.

[QUESTION]What is the expected ratio of offspring with straight ears to offspring with curled ears? Choose the most likely ratio.
[OPTIONS](A) 3:1 (B) 0:4 (C) 1:3 (D) 4:0 (E) 2:2
0:4
To determine how many boxes in the Punnett square represent offspring with straight ears or curled ears, consider whether each phenotype is the dominant or recessive allele's version of the ear type trait. The question tells you that the E allele, which is for curled ears, is dominant over the e allele, which is for straight ears. Straight ears is the recessive allele's version of the ear type trait. An American curl cat with the recessive version of the ear type trait must have only recessive alleles for the ear type gene. So, offspring with straight ears must have the genotype ee. There are 0 boxes in the Punnett square with the genotype ee. Curled ears is the dominant allele's version of the ear type trait. An American curl cat with the dominant version of the ear type trait must have at least one dominant allele for the ear type gene. So, offspring with curled ears must have the genotype EE or Ee. All 4 boxes in the Punnett square have the genotype EE or Ee. So, the expected ratio of offspring with straight ears to offspring with curled ears is 0:4. This means that, based on the Punnett square, this cross will never produce offspring with straight ears. Instead, this cross is expected to always produce offspring with curled ears.

[QUESTION]What is the expected ratio of offspring with brown eyes to offspring with red eyes? Choose the most likely ratio.
[OPTIONS](A) 3:1 (B) 1:3 (C) 2:2 (D) 4:0 (E) 0:4
4:0
To determine how many boxes in the Punnett square represent offspring with brown eyes or red eyes, consider whether each phenotype is the dominant or recessive allele's version of the eye color trait. The question tells you that the E allele, which is for brown eyes, is dominant over the e allele, which is for red eyes. Brown eyes is the dominant allele's version of the eye color trait. A guinea pig with the dominant version of the eye color trait must have at least one dominant allele for the eye color gene. So, offspring with brown eyes must have the genotype EE or Ee. All 4 boxes in the Punnett square have the genotype EE or Ee. Red eyes is the recessive allele's version of the eye color trait. A guinea pig with the recessive version of the eye color trait must have only recessive alleles for the eye color gene. So, offspring with red eyes must have the genotype ee. There are 0 boxes in the Punnett square with the genotype ee. So, the expected ratio of offspring with brown eyes to offspring with red eyes is 4:0. This means that, based on the Punnett square, this cross will always produce offspring with brown eyes. This cross is expected to never produce offspring with red eyes.
