Cigarette smoking and environmental chemicals
Tobacco smoke and certain environmental chemicals are known carcinogens (substances that can cause cancer in living tissue). The tobacco smoke from cigarette smoking contains harmful chemicals such as hydrogen cyanide, arsenic, ammonia, benzene, and many more. In fact, from 2009 to 2013, three out of 10 cancer deaths in the U.S have been attributed to cigarette smoking or exposure to tobacco smoke.
I think the probability would be 50% bc there are four options FF Ff fF and ff. Half of those are heterozygous (the child would be a carrier). So I think it's 50%. However, if we already know that the child will not have the ff combination, then we could say that there are only three other options (so maybe it's 60%?) but that's probably just me being a smartass.
Homologous chromosomes are those chromosomes that are similar in length, centromere location and, gene position. The position of a gene on each homologous chromosomes are same, however, it may contain different alleles.
One of the homologous pairs of a gene is derived from the mother and other from the father. The different form of the same genes is called as an allele.
I dont know what the answer choices are but hope this helps
