Water "beads up" on synthetic fabric such as polyester but binds to cotton. what is the most likely explanation for this?'
choli [55]
The water beads up on synthetic fabric comparable to polyester but impasses to cotton because polyester is nonpolar while cotton is polar. In addition, nonpolar covalent bonds are a kind of chemical bond where two atoms portion a pair of electrons with each other while polar covalent bonding is a type of chemical bond where a pair of electrons is unevenly shared among two atoms.

narvez 5. Everyone in Dobby's family has a long nose and they brag that they are from a purebred line. Viola has a stubby nose.
mote1985 [20]

Assuming a single diallelic gene coding for the trait and expressing complete dominance, the phenotypes, genotypes, and probabilities of getting each of them vary according to the parentals' genotypes. See the options below.

---------------------------------

Since I do not have the genotypes from #2, I will provide <em>different potential scenarios </em>for this question.

I advise you to <em>check on them</em> and see <em>which one matches the genotype from #2.</em>

Let us assume a single diallelic gene is coding for the trait and expresses complete dominance.

<h3 /><h3><u>SCENARIO 1</u>  ⇒ long nose is the dominant trait</h3>

Let us say that

  • L is the dominant allele and codes for long nose
  • l is the recessive allele and codes for stubby nose

Since long nose is dominant over stubby nose

  • LL and Ll ⇒ long nose
  • ll ⇒ stubby nose

If Dobby comes from a purebred family and has long nose, his genotype must be LL.

And if Viola has stubbi nose, her genotype must be ll.

<u>Cross 1</u>

Parentals)    LL   x    ll

Gametes)  L    L     l    l

Punnett square)    L       L

                      l      Ll      Ll

                      l      Ll      Ll

F1) Genotype ⇒ 100% heter0zyg0us Ll

     Phenotype ⇒ 100% long-nosed

  • <em>There is 100% chances for a child to have a long nose</em>
  • <em>There is 0% chances for a child to have a stubby nose</em>
  • <em>These children are not purebred</em>

                                             **********

<h3><u>SCENARIO 2</u>  ⇒ Stubby nose is the dominant trait</h3>

Let us say that

  • S is the dominant allele and codes for stubby nose
  • s is the recessive allele and codes for long nose

Since stubby nose is dominant over long nose

  • SS and Ss ⇒ stubby nose
  • ss ⇒ long nose

If Dobby comes from a purebred family and has long nose, his genotype must be ss.

And if Viola has stubbi nose, her genotype must be either SS or Ss.

There are two possible crosses.

<u>Cross 1</u> : Violet is h0m0zyg0us dominant SS

Parentals)    SS   x    ss

Gametes)  S    S     s    s

Punnett square)   S       S

                      s     Ss     Ss

                      s     Ss     Ss

F1) Genotype ⇒ 100% heter0zyg0us Ss

     Phenotype ⇒ 100% stubby-nosed

  • <em>There is 100% chances for a child to have a stubby nose</em>
  • <em>There is 0% chances for a child to have a long nose</em>
  • <em>These children are not purebred</em>

<u>Cross 2</u>: Violet is heter0zyg0us, Ss

Parentals)    Ss   x    ss

Gametes)  S    s     s    s

Punnett square)   S       s

                      s     Ss     ss

                      s     Ss     ss

F1) Genotype ⇒ 50% heter0zyg0us Ss and 50% h0m0zyg0us recessive ss

     Phenotype ⇒ 50% stubby-nosed and 50% long-nosed

  • <em>There is 50% chances for a child to have a stubby nose</em>
  • <em>There is 50% chances for a child to have a long nose</em>
  • <em>These children are not purebred</em>
