Answer:

a. All will have long tails.

Explanation:

Even though the mother is heterozygous for this trait yet her off springs will show dominant trait because her husband is homozygous dominant for this trait. The mother has one recessive allele but it will not be able to express in the presence of dominant allele even after their mating because father will contribute dominant allele each time.

The cross is depicted as under:

                        Mother             Father

Parental            Tt                       TT

F1                       TT     TT      Tt      Tt        

So all their offsprings will pehnotypically be long tailed because dominant allele (T) will suppress expression of recessive allele (t). 50% progenies will be heterozygous for long tail while 50% will be homozygous dominant for this trait.

Put the steps of DNA Replication in the correct order.
kramer

Answer:

1. The 2 bases forming each rung of the 'ladder' snap apart. This is caused by an enzyme that passes along the strands, 'unzipping' it

2. Spare nucleotides (in the nucleus of the cell) attach themselves to the 'broken rungs' to repair the break. Each repairing nucleotide is identical to the broken one

3. As each 'broken rung' is repaired, two 'ladders' form, that is 2 identical strands of DNA. The 'repairing' is really the process of replica

Hope this helps!
