In the 1860s Gregor Mendel performed numerous dihybrid crosses between pea plants. Dihybrid crosses involve the study of the inheritance patterns related to two different traits. In guinea pigs the allele for black fur (B) is dominant over the allele for brown fur (b), and the allele for short fur (F) is dominant over the allele for long fur (f). What percentage of the offspring from a BbFf x bbff cross would be expected to be heterozygous for both traits

Answers

Answer:

25% of the progeny is expected to be dihybrid, BbFf, expressing Black and short fur

Explanation:

Available data:

the allele for black fur (B) is dominant over the allele for brown fur (b)the allele for short fur (F) is dominant over the allele for long fur (f)Cross: BbFf x bbff

Parentals)            BbFf      x         bbff

Phenotypes) Black/Short    Brown/Long

Gametes)       BF, Bf, bF, bf      bf, bf, bf, bf

Punnett square)      BF         Bf          bF          bf

                      bf    BbFf     Bbff       bbFf       bbff

                      bf    BbFf     Bbff       bbFf       bbff

                      bf    BbFf     Bbff       bbFf       bbff

                      bf    BbFf     Bbff       bbFf       bbff

F1) 4/16 = 1/4 = 25% of the progeny is expected to be dihybrid, BbFf, expressing Black and short fur

    4/16 = 1/4 = 25% of the progeny is expected to be bbFf, expressing Brown and short fur

    4/16 = 1/4 = 25% of the progeny is expected to be Bbff, expressing Black and long fur

    4/16 = 1/4 = 25% of the progeny is expected to be bbff, expressing Brown and Long fur

25%

The law of conservation of energy states that energy cannon be created or destroyed.
O True
O False​

Answers

Answer:

false

Explanation:

The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. For example, turning on a light would seem to produce energy; however, it is electrical energy that is converted.
