Salamanders have a male heterogametic system for sex determinations where females are ZZ and males are ZW. The allele for the color of the tail is sex linked and the red allele is found on the W chromosome and the blue allele is found on the Z chromosome. You mate a male and female and they have 3 female offspring. What is the phenotypic ratio for tail color for their offspring? Group of answer choices 2 Blue : 1 Red 0 Blue : 3 Red 1 Blue : 2 red 3 Blue : 0 Red

96% of Florida panther population has normal tails.  4% of the Florida panther population has the crook in the tail. Crooked tails are recessive.      Find the dominant allele frequency and the recessive allele frequency.  Construct a Punnett Square that would illustrate the phenotypic outcome of the a parent who is homozygous for a normal tail and homozygous for a crooked tail.  Include a Punnett square illustrating the cross.  Include a “key” or “legend” describing the pattern of inheritance for the trait, the genotypes of the parents, and the phenotypic percentages of the outcome of the cross.

This is my question

I need help with this question

A population of llamas exhibits Type I survivorship. It has a nice life span and but fewer offspring. Which of the following best represents the type of survivorship the llama population is given this information?

Sample A Sample B Sample C Habitat type Sand dunes Grassland Grassland Morph Pink unbanded 1 Pink mid-banded 28 Pink many-banded 45 Yellow unbanded 23 57 Yellow mid-banded 20 12 28 Yellow many-banded 38 78 160 Brown unbanded 70 42 Brown mid-banded 15 25 Brown many-banded 103 83 Total in sample 132 301 395 a. Summarise the data on morph frequencies, allele frequencies and index of polymorphism for the three populations in a table.
