Question

What percentage of the offspring will be heterozygous for all six genes?

Aa bb Cc Dd Ee Ff x AA BB Cc DD EE ff

Answer #1

Ans :-) In the given problem, one parent has genotype AabbCcDdEeFf and other has genotype AABBCcDDEEff.

For gene A there will be cross of Aa X Aa. The probability of having heterozygous genotype Aa will be 2/4 =1/2

For gene B, there will be a cross of bb X BB. The probability of having heterozygous genotype Bb will be 4/4 =1

For gene C, there will be cross of Cc X Cc. The probability of having heterozygous genotype Cc will be 2/4 =1/2

For gene D, there will be cross of Dd X DD. The probability of having heterozygous genotype Dd will be 2/4 =1/2

For gene E, there will be cross of Ee X EE. The probability of having heterozygous genotype Ee will be 2/4 =1/2

For gene F, there will be cross of Ff X ff. The probability of having heterozygous genotype Ff will be 2/ =1/2

Hence the probability of offspring having all the heterozygous genes will be 1/2 *1 *1/2*1/2*1/2*1/2 =1/32

The following two genotypes are crossed: Aa Bb Cc dd Ee
× Aa bb Cc Dd Ee. The proportion of the offspring that are
expected to be aa bb Cc Dd Ee assuming Mendelian
inheritance is ___.

If 400 offspring result from a Aa Bb x Aa Bb cross, how many
offspring are expected to be: AA bb?

In the context of
multihybrid crosses and using the cross Aa Bb Cc X Aa Bb Cc, how
many progeny will show the recessive traits for A and B and show
the Dominant Trait for C?

Morris Industries manufactures and sells three products (AA, BB,
and CC). The sales price and unit variable cost for the three
products are as follows:

Their sales mix is reflected as a ratio of 5:3:2. Annual fixed
costs shared by the three products are $234,000 per year.

Write the rate law of the general equation given below and
explain what is meant by the overall order and individual reactant
order. aA + bB + cC → dD + eE A. Are the reaction order and
stoichiometric coefficient related to each other? B. Does the
reaction order have to always be a positive integer number? C. What
is the rate constant? D. Does the rate constant depend on
temperature? Be able to use stoichiometry to define a single...

In a trihybrid cross, what is the percentage of the
offspring omozygous for all three genes?
To solve this, I considered that for each gene half the offspring
is omozygous, so I would say (1/2)*(1/2)*(1/2)=1/8. The problem is:
when I checked my answer by sketching the Punnet square, I found
out that 1/32 of the offspring is omozygous for all three genes.
So, what is the right answer? Thanks in advance!

Learning Goal: To understand reaction order and rate constants.
For the general equation aA+bB?cC+dD, the rate law is expressed as
follows: rate=k[A]m[B]n where m and n indicate the order of the
reaction with respect to each reactant and must be determined
experimentally and k is the rate constant, which is specific to
each reaction. Order For a particular reaction, aA+bB+cC?dD, the
rate law was experimentally determined to be
rate=k[A]0[B]1[C]2=k[B][C]2 This equation is zero order with
respect to A. Therefore, changing...

In a generic chemical reaction involving reactants A and B and
products C and D, aA+bB→cC+dD,
the standard enthalpy ΔrH∘ of the reaction is given by
ΔrH∘=cΔfH∘(C)+dΔfH∘(D)
−aΔfH∘(A)−bΔfH∘(B)
Notice that the stoichiometric coefficients, a,
b, c, d, are an important part of this
equation. This formula is often generalized as follows, where the
first sum on the right-hand side of the equation is a sum over the
products and the second sum is over the reactants:
ΔrH∘=∑productsnΔfH∘−∑reactantsmΔfH∘
where m and...
