What is probability, and how is it used with Punnett squares to predict the outcomes of genetic crosses?
weeeeeb [17]

Answer:

Probability is the chance that a given event will occur. The principle of probability allows us to predict the possible combinations of phenotypes in a genetic cross by using a diagram called Punnett squares. This diagram represents alleles and gives us the genetic variations formed during a cross. For example, a flower has one dominant allele for a blue color, which is represented by capital T, and one recessive allele for a pink color, which is represented by small t. When this flower is crossed with another flowering plant with the same type of alleles, which is Tt, the combinations produced for their offspring includes TT, Tt, tT, and tt.

Tall height is dominant to short height in pea plants. You have a tall pea plant that you cross with a short pea plant. What is
zheka24 [161]

Answer:

The tall parent was heterozygous

Explanation:

If tall height is dominant to short height the only genotype possible for short height is hh, while there are two possible genotypes for tall height, Hh and HH. When HH is crossed with hh all the offspring are Hh, but if Hh is crossed with hh, a quarter of the offspring is HH, a quarter is hh and half is Hh. If the tall pea plants were HH there would only be tall offspring, but because there are some short offspring we know that the tall pea plants must have a genotype of Hh.
