Answer #1

Here mother is a heterozygous dominant (Bb) and father is homozygous reccessive(bb).Alleles are B for hazel eyes and b for blue eyes.mother have two alleles one for hazel eyes and other for blue eyes,but father have both alleles for blue eyes.From the punnet square,we got the genotypic and phenotypic ratio as:

genotypic ratio :heterozygous domonant:homozygous recessive = 2:2

phenotypic ratio:hazel eyes :blue eyes =2:2

ie,phenotypes are 50% offsprings with hazel eyes and 50% offsprings with blues eyes ,equal probability for both.

genotypes are 50% with heterozygous dominant and 50% with homozygous recessive.

Traditionally, blue-eye color is considered recessive to brown eyes in humans although, as noted in the chapter, eye color in humans is not a single gene trait. It has occasionally been the subject of folklore and “common knowledge” that blue-eyed parents usually have blue-eyed offspring. However, blue-eyed parents do often have brown-eyed children. In addition, when one brown-eyed child is born in this family, it is expected that subsequent children will also have brown eyes. Assuming the blue eyes really...

The sepia (se) eye mutation is a non-lethal recessive mutation located on chromosome III in Drosophila (it is not sex-linked, the sex chromosome is chromosome I). Predict the results of a monohybrid cross (F2 generation) with the following parents: a homozygous wild- type female fly and a male fly with sepia eyes. Use a se+ for wild type and se for the mutation. What are the Parental genotypes? ________ The F1 genotypes? _______ Draw a Punnett square to determine the...

.  Eye color of the Oriental fruit fly (Bactrocera dorsalis) is determined by two genes that interact.  A true-breeding fly having wild-type eyes is crossed with a true-breeding fly having yellow eyes.  All of the F1 flies from this cross have wild-type eyes.  When the F1 flies are interbred, 394 of the F2 progeny have wild-type eyes, 131 have amethyst (a bright, sparkling blue color) eyes and 175 have yellow eyes. a).  Based on the number of progeny produced in the cross between F1 flies,...
