Rather than studying you are watching Maury. A couple comes on with a baby The father has brown eyes, his parents, grandparents, sister, and brothers all have brown eyes. The mother has blue eyes and the baby has blue eyes. The brown eye allele is dominant to blue eye allele. Using this information, answer the following question? Based on the Punnett Square, what are the chances that these are the parents of the child?

One form of red-green color blindness is an X-linked recessive trait. A heterozygote woman has children with a normal man. List the gene or genes involved and define all allele symbols.

The image shows a pair of homologous chromosomes from a single parent before gamete production. M1 and M2 are maternal chromosomes, while P1 and P2 are paternal chromosomes. Two traits are shown: D represents seed color (D – green, d – yellow), while F represents flower color (F – purple, f – white). These two traits follow the patterns of basic Mendelian genetics. During crossing-over between the M2 F allele and the P1 f allele, a mutation occurred and the portion of P1 did not reattach to the chromosome. Which of the following explains what would happen to the proportion of white flowers in a population resulting from this mutation? A - There would be an increase in the proportion of white flowers because the f allele is distributed to more gametes. B - There would be a decrease in the proportion of white flowers because the f allele is not distributed to as many gametes. C - There would be an increase in the proportion of white flowers because the f allele would not be masked by the…

Baldness is a recessive, X-linked trait. Mom has a full head of hair but she is a carrier for baldness and her husband has a full head of hair. What are the chances of they having a child who is bald? 0% (no chance)   50%   75%   100% (all of them will be)   25%
