These traditional Inuit foods include arctic char, seal, polar bear, and caribou — often consumed raw, frozen, or dried. The foods, which are native to the region, are packed with the vitamins and nutrients people need to stay nourished in the harsh winter conditions.
Answer:
Let the "barred" allele be caller B and the "non-white" allele b. Since chickens use chromosomes
and
to determine sex, hens would have chromosomes
, and roosters would have chromosomes
. A Z-linked gene is represented as a superscript on the
chromosome,
for the dominant allele and
for the ressesive allele.
A barred hen would have a copy of B on its Z chromosome, a non-barred rooster would have both copies of b on both Z chromosomes. Using Punnet squares to represent the crosses we get the following cases:

That is a ratio of two barred heterozygote roosters to two non-barred hens. Crossing them we get:

That is a ratio of one barred heterozygote rooster to one barred hen to one non-barred rooster to one non barred hen.
