It is caused by one gene with a large number of alleles. C. It affects a large number of people. D. It has many different symptomsarrow_forwardA researcher studies a mutation that occurs in humans and writes four facts about the mutation in a chart. 1. The mutation is caused as a result of chance. 2. The mutation leads to a genetic disease. 3. The mutation occurs in sperm cells and is passed to the next generation. 4. The mutation is not discovered or fixed by the cell's enzymes. Based on the information, the researcher concludes that the mutation is harmful.

The child does not have brown pigment at birth B. Eye’s colour at birth is affected by mother’s gene C. Gene repressor for brown pigment produced is not yet active D.

One mutant strain is called naked, and the other is hairless. the scientist crosses naked and hairless mice with each other to determine whether the two mutations are different alleles. All the offspring lack hair on their bodies a: Are naked and hairless different mutations two alleles? Why or why not? b: What type of genetics experiment is this called? What is the significance of this test?arrow_forwardThe drug tamoxifen has been used to treat some types of breast cancer. Suppose even among female patients with the same tumor grade there is variation in responsiveness to tamoxifen. It is also found that this variation is at least partly genetic; his variation is at least partly genetic; women with a relative who had a low responsiveness to the drug are at higher risk of low responsiveness to the drug The target of tamoxifen is a protein called the estrogen receptor. A. Outline how a “candidate gene approach” could be conducted to investigate whether variation in the gene for estrogen receptor affects tamoxifen responsivenessarrow_forward
