MrMuchimi

50 percent of the offspring would be expected to have the ability to roll their tongues If a heterozygous male is crossed with a homozygous recessive female.

Explanation:

Information given:

the ability to roll tongue is dominant, the genotype would be RR, Rr

the inability to roll tongue is recessive trait the genotype = rr

Given that heterozygous male is crossed with homozygous recessive female, the genotype is

Rr X rr

Punnet square shows that:

    R    r

r   Rr  rr

r  Rr  rr    The genotype ratio is 1:1

                 phenotype ratio is 1:1

There are chances of 50 % offspring having the ability to roll their tongues as they are heterozygous and have the dominant allele for rolling of tongues.

What is the association between tropomyosin and troponin molecules in resting striated muscle fibers?
ryzh [129]
The correct answer is that "t<span>roponin holds the tropomyosin in place on the actin".

In excitation-contraction coupling, tropomyosin prevents the interaction between actin and myosin in resting muscles. In the event of excitation, there is release of calcium from the sarcoplasmic reticulum wherein the troponin will bind this calcium and will release tropomyosin and expose myosin enabling it to attach to actin and therefore facilitating muscle contraction.</span>
