Here we can see that 7 phenotypes appeared in F2 generation, so the number of genes involved is 3 and alleles is 6. Contribution per allele = 4 cm Base contribution = 6 cm

Genotype of Harvey = aa bb cc Genotype of Erma = AA BB CC

Number of dominant alleles if length is

18 cm = 18-6 / 4 = 12 / 4 = 3.

F1 generation genotype = Aa Bb Cc This clarifies why the length is 18 cm, as there are three dominant alleles.

seven 1. It is likely that there are gene pairs in this cross. There are

categories of phenotypes. The genotypes of the parents would be combinations of alleles that would produce a 6 cm ( aabbcc ) tail and a 30 cm) tail, whereas the 18 cm offspring would have a genotype of AaBbcc.

-Dominant- [34]

Answer:

Ralph is looking at a vein (likely a muscular vein).

Explanation:

Of all three great types of vessel present in vertebrates (arterial, venous, lymphatic), only veins and lymphatic vessels may normally contain valves.  This is an essential feature of vessels which present low pressure flow, since it ensures that such flow is unidirectional.

Since blood cells are not typically found in lymphatic vessels, the vessel in question can be assumed to be a vein.

How does the work of scientists lead to knowlage
jolli1 [7]

Scientists carry out several researches to understand the cause and reason behind the natural phenomena happening around us. While carrying out an experiment, the scientist need to refer to various research papers and research articles to plan and follow the protocol of the experiment accordingly.

Going through the background studies lead to greater insight and knowledge about the subject. It broadens our mind and way of thinking. It makes us more logical and precise towards our work.
