I need help with genetics, i am really confused.


In humans, colorblindness is a recessive, sex-linked trait. What is the percentage chance that a child of a woman heterozygous for colorblindness and a man with normal color vision will be colorblind?

and another question that is exactly like that but with the child being a boy....

I have no idea how to complete this problem. It must be a numerical answer. It cost a bicycle company $9000 to make 50 touring bikes in its first month of operation and $15000 to make 125 bikes during its second month. Estimate the cost of producing 252 bikes in the third month assuming that the relationship between the cost and the number of bicycles produced is linear.

An electron and a proton are initially very far apart (effectively an infinite distance apart). They are then brought together to form a hydrogen atom, in which the electron orbits the proton at an average distance of 5.32 10-11m. What is EPEfinal - EPEinitial, which is the change in the electric potential energy?

two teams are playing in a championship. they each have equal probability of winning the first game. for the remaining games, whoever won the last game has a psychological high, so they now have a 2/3 chance of winning the next game. the championship ends when one team has won W more games than the other. what's the expected number of games that will be played?

hint:Focus on the difference between the number of games won by team A and the number of games won by team B. Initially, this difference is zero, and with each game, it increases or decreases by one. The tournament ends when this difference reaches W or W
