The gene for a certain syndrome is present on a Y chromosome. A man carries the gene for this syndrome. Which of the following is true about the inheritance pattern of the syndrome? A.) Only his son would have the gene for the syndrome. B.) Only his daughter would have the gene for the syndrome. C.) Both son and daughter would have the gene for the syndrome. D.) Neither son nor daughter would have the gene for the syndrome.

A.) Only his son would have the gene for the syndrome.

Explanation:

This is because during sexual reproduction (that is, between humans), the mother and father each donate a sex chromosome. The mother can only donate an X chromosome since her sex chromosomes are entirely X chromosomes, and the father can donate either an X or Y chromosome since his sex chromosomes are X and Y. Thus, because a male has the sex chromosomes X and Y whereas a female has the sex chromosome X and X, the male must donate a Y chromosome for a son to be born; otherwise he donates an X chromosome and the baby is female. As you can see, because the gene is on a Y chromosome and the father carries and passes it (only to a son), only his son would have the gene for the syndrome.

answer: i don't know

explanation:

you need to provide a picture, otherwise i can't tell you.

if you can provide one, i'd be more than happy to you with this!

picture a world where computers are building made-to-order personalized robotic arms and synthetic organs, drones are circulating above mars! due to the rapid growth of technology, the future has never been more unpredictable, and it presents a huge challenge in education: we are teaching students how to work in a future that we have never been unsure of. it is widely predicted that in eight years’ time, there will be more jobs in the fields of science, mathematics, technology and engineering than in any other discipline. and, as the technology continues to develop, it will soon become clear that addressing social problems will involve more innovative thinking, and analytical and technical knowledge than ever before. undeniably, there are no subjects that encourage innovative and creative thinking, deep thought, problem solving and independence more than the stem subjects. while it is widely commented on that there is a need to reimagine the ways stem subjects are taught in schools by embracing a more interactive and innovative approach to appeal to more students, it should come as no surprise that some of the most reputable educational organizations in the world are already implementing changes to embrace stem. harvard, for example, announced in 2014 that they were increasing their computer science faculty by over 50% and has since introduced computer science as a core subject for all freshmen. the urgency of supporting stem subjects at a young age is becoming more relevant than ever, as adopting a keen interest in the curricula needs to happen early. however, beyond the age issue is one of gender.
