In some cats the gene for tail length shows incomplete dominance. Cats with long tails have the genotype “LL”. Cats with short tails are “LS”, while cats with no tails at all are “SS”. For each of the following construct a Punnett square and give the genotypic and phenotypic ratios of the offspring.

a) A long tail cat (LL) and a short tail cat (LS)
Genotypic Ratio:

Phenotypic Ratio:

b) A long tail cat and a cat with no tail
Genotypic Ratio:

Phenotypic Ratio:

c) A short tail cat and a cat with no tail
Genotypic Ratio:

Phenotypic Ratio:

d) Two short tail cats
Genotypic Ratio:

Phenotypic Ratio:

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.

Knowing the importance of the essential elements, why would someone chose a diet that does not address all of them?
