Answer:
DNA can be described as the molecules which carries the genetic code for every individual. The DNA is made up of nucleotide bases which join the two strands of DNA. The sugar and phosphate form the backbone of the DNA.
Genes are the hereditary molecules which are made up of DNA. The alleles of a gene represent which traits will be carried by an organism.
Chromosomes are made up of genes. During reproduction, crossing over of DNA occurs and alleles of the genes assort independently due to which variations occur.
Yes plant cells do have mitochondira
<span>My pea plant has an unknown genotype for flowers, whether it has two dominant traits for white flowers (WW) or one dominant and one recessive (Ww) leading to white flowers; therefore I am doing a testcross in order to determine the genotype of my pea plant. The best plant to do this with is one that has a phenotype of purple flowers (ww) - that is, it is homozygous for the recessive trait.
If I use a homozygous recessive plant, I know exactly what its genotype is. I don't have to worry about whether it's got one or two dominant alleles; I know that at least half of my alleles are going to be the recessive w.
This makes identifying the offspring's genotype very simple. If I find that the offspring have at least some purple flowers among them, I know that my original plant had to be Ww; that is it had to have one dominant and one recessive allele for the flower color gene. If, however, all of the offspring are white flowers, I know that my original pea plant had both dominant alleles (WW).</span>
Answer:
I'm pretty sure it is 'some species depend on disterbences'
Answer:
In cabbage butterflies, White wings are dominant to yellow wings. Create a Punnett Square that shows the offspring that results if a Ww butterfly is crossed with a ww butterfly. Create a Punnett Square. What percentage of the offspring will have yellow wings? and What is the phenotypic ratio (color ratio)?
Ww x ww= Ww, Ww, ww, and ww
50% has yellow wings
The phenotypic ratio is two white wings butterflies and two yellow wing butterflies 2:2 50%:50%
