The punnett square predicts the ratio of genotypes in the offspring, based on the genotypes of the parents. the punnett square below examines the chance of offspring having freckles, which is a dominant trait. a punnett square is shown. the columns are labeled upper f and f. the rows are labeled upper f and f. clockwise from upper left the boxes contain: upper f upper f, upper f f, upper f f, f f. based on the punnett square, what is the probability that the offspring will have freckles? 25 percent 50 percent 75 percent 100 percent

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.

thats not a question

not always but somethings can be reproduced in a laboratory.
