Question

In a monohybrid cross, if the gene for tall (T) plants was incompletely dominant over the gene for short (t) plants, what would be the predicted result of crossing two intermediate (Tt) parent plants? (Hint: You may want to complete a Punnett square.)
A. 25% tall, 50% intermediate, 25% short
B. 25% tall, 75% intermediate
C. 50% tall, 25% intermediate, 25% short
D. 100% intermediate

Answer 1

i set up a punnet square, but still dont get it

Answer 2

1 TT : 2 Tt :1tt
1 tall: 2 intermediate : one short

i hope this helps.

Answer 3

thanks so much!

Answer 4

know this one--??


In guinea pigs, dark hair (D) is dominant over light hair (d) and curly hair (C) is dominant over smooth hair (c). Complete a dihybrid cross for parents with the genotypes: DdCc × DdCc and answer the following in complete sentences.

Describe how you would set up a Punnett square for this cross.
List the likelihood of each possible offspring genotype.
List the likelihood of each possible offspring phenotype.

Answer 5

been trying it for a while but i just cant make a good sqaure for it

Answer 6

Please Help.. Im still trying but not getting anywhere

Answer 7

If you have a parent genotype which is DdCc, the possible gametes is DC, Dc, dC and dc (4 different combinations). When you cross these 4 posibles choices of gametes with another 4 possible gametes, you have 9 different genotype and 4 different phenotype.
