Water Buffalo have large feet with hooves that spread, making it easier for them to walk in soft mud. Some Water Buffalo may have a corkscrew claw, which makes walking their terrain more challenging.

Question

From Jumping Ants to Water Buffalo ...



The diagram below shows some of the inheritance patterns of corkscrew claw in Water Buffalo over 3 generations. Place the genotype labels in the blank boxes of the F1 generation that result in the F2 generation shown.

Place only one label in each box.
You may use each label more than once.
You do not need to use all the labels.
There may be more than one correct answer.

Answer 1

To appropriately fill in the genotype labels in the F1 generation that result in the F2 generation of Water Buffalo with possible corkscrew claws, we must first identify the potential genotypes that could lead to the observed inheritance patterns.

Let's denote:

• "C" as the allele for the normal claw (dominant)
• "c" as the allele for the corkscrew claw (recessive)

Based on these definitions, possible genotypes for the Water Buffalo are:

• CC (homozygous dominant) – normal claws
• Cc (heterozygous) – normal claws but a carrier of the corkscrew trait
• cc (homozygous recessive) – corkscrew claws

To determine the F1 generation, we need to consider the specific outcomes in the F2 generation. Assume the F2 generation displays a phenotypic ratio of 3 normal claws (CC or Cc) to 1 corkscrew claw (cc). This would indicate that F1 generation parents were likely heterozygous (Cc x Cc).

In that case:

F1 Generation:

1. Cc
2. Cc

The resulting F2 generation would then have the following genotypic ratio:

• 1 CC (normal)
• 2 Cc (normal)
• 1 cc (corkscrew)

If you have specific genotype labels to fill in for the F1 boxes, you can input "Cc" in both boxes, as they are expected to produce the outlined F2 generation.

If you have specific genotype labels provided and would like to fill in the F1 generation accordingly, please provide those labels for further assistance.
