Let's imagine that two genes of the genotype can be analysed separately.
Black fur is determined by dominant allele B. In this case, parents Bb and BB will give offspring with only brown fur: Parents: Bb x BB Offspring: BB BB Bb Bb Both homozygous (BB) and heterozygous (Bb) offspring will have black fur.
On the other hand, long tails are determined by recessive allele t. Parents Tt and tt will have 50% offspring with short tail and 50% offspring with long tail: Parents: Tt x tt Offspring: Tt Tt tt tt Heterozygous offspring (Tt) will have short tail, and homozygous offspring (tt) will have a long tail.
So, the offspring will definitely have black fur and will not affect the fraction of the offspring with black fur and long tails from the cross of <span>BbTt × BBtt. But, </span>there will be 2 out of 4 offspring with short tails which is 50% or 1/2.
Scientists use radio technology in order to track endangered species. These include radio collars, tags and chips. These devices can then be tracked wither via satellites through GPS technology or by locating the radio waves emitted by these devices using receivers. These devices have proven very helpful in tracking organisms and monitoring their populations.
A colony on an agar plate that is slightly and equally elevated and unbroken would be classified as circular form of colony. These are pinhead colonies which are usually convex on its entire margins. These form of nutrient agar plates are usually<span> raised or elevated and unbroken.</span><span> </span>
Explanation: The shape of a protein is determined by its primary structure (sequence of amino acids). The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene (DNA) encoding it.
