The husband files for divorce on the grounds of his wife's infidelity. Explain the mode of inheritance of character and the conditions under which the lawyer of the husband can use the birth of the affected daughter as proof of infidelity.

6. A brown-eyed man, whose mother was blue-eyed, marries a blue-eyed woman. The man is red-green colour blind and his wife has normal colour vision although her father was also colour blind. (Note: brown eyes is dominant over blue eyes and eye colour is inherited autosomally. Red-green colour blindness is a sex-linked recessive trait). a) What are the genotypes of the man and his wife with respect to these two traits? Ger b) Complete the...

A man who has pointed ears came to the attention of a geneticist. The geneticist finds the following: Pointy ears are an inherited trait due to a single genetic locus. The man's sister has pointed ears, but his mother, father, his brother, and other sister have normal ears. The man and his normal-eared wife are first cousins and have seven children, including four boys and three girls. Two girls and two boys have pointy ears; the boys with pointy ears...

the two cream colored guinea pigs produced, in one case, 22 yellow. 47cream, and 19 white. What type of inheritance is this? II. Sex-linked Characteristics 12. In man, colorblindness, an inability to distinguish between red and green, is inherited as a sex-linked character on the X chromosome. It is recessive. If a colorblind man marries a homozygous normal woman what chance is there for the children of being colorblind? If a normal man marries a colorblind woman. where will colorblindness...
