Okay so a dominant gene is a gene that will always be expressed within an offspring if it is present, a recessive gene requires to alleles to be shown within an offspring.
So.. for 9
A heterozygous black dog mates with a yellow dog
If something it heterozygous and exhibits the black trait or color then it must mean that black was dominant because if black was recessive then it require two alleles to "code" for it so...
B --> black
b --> yellow
So the genotype of the black dog must be Bb
and the genotype of the yellow dog is bb
Hopefully this makes sense, but let me know if you need help with any other questions.
If I did a punnet square to check
Bb x bb
b b
B Bb Bb
b bb bb
So half of the puppies are yellow and the other half are black.
Answer:
The regularity of DNA's overall structure.
Explanation:
DNA is the genetic material of almost all the living organisms but RNA may also acts as the genetic material in some viruses only. The mutation in DNA may cause characteristic disease in individual.
The nucleotide excision repair mechanism excise the wrong nucletide and replace with the correct nucleotide. The overall DNA structure like its nucleotide sequence, the size and angles between the DNA base pair, its methylation helps in recognizing different DNA type.
Thus, the correct answer is the regularity of DNA's overall structure.
Answer:
I know that the nucleus is the big boss of the cell, and the chlord past is ONLY in plants
I hope this helps
gymnoseperms meaning "naked seeds" are a diverse group of seed plants and are paraphyletic. paraphyletic groups are those in which not all members are descendants of a single common ancestor. gymnoseperm seeds are not enclosed in an ovary; rather, they exposed in cones or modified leaves
