1. How many different phenotypes are found among the progeny of the cross listed below?
a.)
Aa |
Bb | dd | Ee | x | AA | bb | Dd | ee |
b.)
aa | bb | Dd | ee | x | AA | Bb | Dd |
Ee |
c.)
aa | Bb | dd | Ee |
Answer a)
Aa |
Bb | dd | Ee | x | AA | bb | Dd | ee |
As phenotype for A would be dominant only whether it is AA or Aa , for B it would be dominant (Bb) or recessive(bb), for D it would be dominant (Dd) or recessive (dd), for E it would be dominant (Ee) or recessive (ee)
So, Total possible phenotypes = 1x2x2x2 = 8 i.e.

Answer b)
aa | bb | Dd | ee | x | AA | Bb | Dd |
Ee |
As phenotype for A would be dominant (Aa) , for B it would be dominant (Bb) or recessive(bb), for D it would be dominant (DD, Dd) or recessive (dd), for E it would be dominant (Ee) or recessive (ee)
So, Total possible phenotypes = 1x2x2x2 = 8

Answer c) Only one genotype is given, So, if self crossing is assumed, aaBbddEe x aaBbddEe
Gametes are aBdE, aBde, abdE, abde
As phenotype for A would be recessive only (aa) , for B it would be dominant (Bb) or recessive(bb), for D it would be only recessive (dd), for E it would be dominant (Ee) or recessive (ee)
So, Total possible phenotypes = 1x2x1x2 = 4 i.e.

The following two genotypes are crossed: Aa Bb Cc dd Ee x Aa bb Cc Dd Ee. What will be the proportions of the following genotypes among the progeny of this cross? a.AaBbCcddEe b.AAbbCCddEE
Consider the cross (assume a capital allele is dominant to a small case allele): Aa Bb Cc Dd Ee X aa Bb cc Dd ee a) What proportion of the progeny will resemble phenotypically: (1) the female parent? (2) the male parent? (3) either parent? (4) neither parent? b) What proportion of the progeny will resemble genotypically: (1) the female parent? (2) the male parent? (3) either parent? (4) neither parent?
Given the Mendelian cross: Aa Bb gg Dd Ee Hh (father) X Aa Bb Gg dd ee Hh(mother). How many gametes are made by the father? How many by the mother? Select one: a. ¾, 1/4 b. 8,8 c. 32, 32 d. 64, 32 e. 32, 16 f. 16, 8

Genetics questions. please be 100% sure in your answer. thank
you!!! Someone says this needs to be updated but this is the exact
question my professor has given us. So theres nothing else I can
write.

I'm having trouble understanding this problem. The most frequent
F2 progeny seem to have had crossover to me because the parents are
Aa Bb x aa bb but the progeny are Aa bb and aa Bb. I thought
parental progeny would have the same genotype as the parents. Can
you please explain how the most frequent progeny don't have
crossover? Thank you

2. Consider the cross Aa Bb Cc Dd X aa Bb cc dd. All of the genes are on mes. What proportion of progeny will phenotypically resemble the second parent (i.e. the parent listed second in the cross)? Show each individual cross AS OUTLINED IN CLASS. Punnett squares are NOT allowed. Also, show the final calculation to get your answer. In other words, show all of your work.
