Genetics exercises can be used to illustrate various situations, such as monohybrid cross, dihybrid cross, sex-linked inheritance, polygenic inheritance, among other topics related to molecular biology and human cytogenetics. What are the two areas related to genetics?

Read the following text: Genetics has allowed many contributions to the understanding of living beings. One contribution was to quantify the possible occurrence of a fact, based on a known situation. So, using your genetics knowledge, consider the following situation: 'A man with normal vision marries a woman with normal vision, but her father was color blind.' Considering that this couple wants to have a child, then the probability of: I. being born a boy is 50%. II. being born a color blind boy is 25%. III. being born a color blind girl is 25%. IV. being born a child with the same genotype as the parents is 50%. Choose the CORRECT alternative.

Expression of the gene responsible for the production of the normal enzyme.

The National Health Surveillance Agency (Anvisa) has approved a gene therapy product in the country, indicated for the treatment of hereditary retinal dystrophy. The procedure is recommended for children over 12 months and adults with vision loss caused by the mutation of the human gene RPE65. The product, developed through genetic engineering, consists of a virus into which a copy of the normal human gene RPE65 has been inserted to correct the functioning of the retinal cells. (ANVISA. Available at www.gov.br/anvisa. Accessed on Dec 4, 2021. Adapted.) The success of this therapy stems from the fact that the product will promote the...

In the human species, the gene that determines color blindness is characterized by a type of inheritance called:

According to the rules of Lexical Divergences, the lexical units terapias and cerebro can be classified as:

To solve this question, we need to understand the concept of Lexical Divergences. These divergences occur when two words, written the same way or similarly, have different meanings in different Spanish variants. The words terapias and cerebro do not present lexical divergences, as they have the same meaning in all Spanish variants. However, we can classify them as heterotonic, as the stressed syllable in terapias is the penultimate one (te-RA-pi-as) and the stressed syllable in cerebro is the antepenultimate one (ce-RE-bro). Therefore, the correct answer is that both words are heterotonic.
