Answer #1

Ans. (C)

As the condition is autosomal dominant the genotype of women must be AA or Aa. whereas, the genotype of her husband must be aa.

if the genotype of the women is AA then all of her offsprings must be phenotypically expressing this condition but 100 percent is not an option to choose. so i am assuming that the women must be heterozygous i.e., Aa

a a
A Aa Aa
a aa aa

As the cross shows this condition is expected to be phenotypically expressed in 50 %  of her offspring i.e., the Aa individuals.

There is an autosomal gene responsible for the formation of a so-called widow’s peak in human hairlines. The allele that causes the peak is dominant. Twenty-five percent of people do not have a peak (peakless). A man with a peak whose mother was peakless marries a woman with a peak. Her peak “ancestry” is unknown. The alleles are in Hardy-Weinberg equilibrium. What is the probability that the couple’s first child will have a peak? A. Can’t be determined B. 0.83...

assignment baldness In man, a gender-influenced character is determined by two alleles in an autosomal locus. Allel B for baldness is dominant in men, but recessive in women. The alternative allele b is recessive in men, but dominant in women. In a large population (A) it turned out that 1% of the women were bald. Answer the following questions assuming that the population is in Hardy-Weinberg's balance with regard to the genetic system considered. a) Calculate the expected frequency of...
