Answer:

The correct genotype would be-

mom: homozygous recessive, father: heterozygous or homozygous dominant, and son : 50%(if father heterozygous dominant) to 100%( if father is homozygous dominant) chances of being hetrozygous dominant.

Explanation:

Listing the genes in the way that they indicates the real combination of alleles is the genotype of individual.

Ability to roll your tongue is a dominant character which has a dominant and a recessive gene. Assume that the dominant allele ‘R’ is for the ability to rolling tongue and the recessive allele ‘r’ for unable to rolling our tongue. As we know mother can not roll her toungue she must have homozygous recessive alleles that means she has two copy of recessive allele. The father could posess any combination of these alleles: RR (homozygous dominant), or Rr(heterozygous dominant).

Thus, the correct genotype would be

mom: homozygous recessive, father: heterozygous or homozygous dominant, and son : 50%(if father heterozygous dominant) to 100%( if father is homozygous dominant) chances of being hetrozygous dominant.

Sergeu [11.5K]
The nurse response in related to the patient's query about feeling nauseated at the sight of meat is that this condition will go away in three months. Nausea and vomiting are included in early symptoms of pregnancy and in pregnancy the HCG (human chronic gonadotropin) levels are increased and due to this many women feel nauseated.
