Question: [QUESTION]What is the expected ratio of offspring with a reddish-brown coat to offspring with a black coat? Choose the most likely ratio.
Solution: To determine how many boxes in the Punnett square represent offspring with a reddish-brown coat or a black coat, consider whether each phenotype is the dominant or recessive allele's version of the coat color trait. The question tells you that the L allele, which is for a black coat, is dominant over the l allele, which is for a reddish-brown coat.
A reddish-brown coat is the recessive allele's version of the coat color trait. A horse with the recessive version of the coat color trait must have only recessive alleles for the coat color gene. So, offspring with a reddish-brown coat must have the genotype ll.
There are 2 boxes in the Punnett square with the genotype ll. These boxes are highlighted below.
A black coat is the dominant allele's version of the coat color trait. A horse with the dominant version of the coat color trait must have at least one dominant allele for the coat color gene. So, offspring with a black coat must have the genotype LL or Ll.
There are 2 boxes in the Punnett square with the genotype LL or Ll. These boxes are highlighted below.
So, the expected ratio of offspring with a reddish-brown coat to offspring with a black coat is 2:2. This means that, on average, this cross will produce 2 offspring with a reddish-brown coat for every 2 offspring with a black coat. | TheMrguiller/ScienceQA |

Question: [QUESTION]What is the expected ratio of offspring with a gray body to offspring with a golden body? Choose the most likely ratio.
Solution: To determine how many boxes in the Punnett square represent offspring with a gray body or a golden body, consider whether each phenotype is the dominant or recessive allele's version of the body color trait. The question tells you that the b allele, which is for a golden body, is recessive to the B allele, which is for a gray body.
A gray body is the dominant allele's version of the body color trait. A guppy with the dominant version of the body color trait must have at least one dominant allele for the body color gene. So, offspring with a gray body must have the genotype BB or Bb.
There are 3 boxes in the Punnett square with the genotype BB or Bb. These boxes are highlighted below.
A golden body is the recessive allele's version of the body color trait. A guppy with the recessive version of the body color trait must have only recessive alleles for the body color gene. So, offspring with a golden body must have the genotype bb.
There is 1 box in the Punnett square with the genotype bb. This box is highlighted below.
So, the expected ratio of offspring with a gray body to offspring with a golden body is 3:1. This means that, on average, this cross will produce 3 offspring with a gray body for every 1 offspring with a golden body. | TheMrguiller/ScienceQA |
