The statement is True.
In Microsoft Office Excel, when the text inside a cell is longer than the width of the cell it overflows the display on the next adjacent cell on the right as long as its an empty cell. If there is a data, the other text will be hidden unless you click on Wrap text.
Meiosis is the cell division in which there is a formation of chiasmata......which lead to variation......
Answer:
bright blue trait = recessive
yellow trait = dominant
Explanation:
let the letter B represent the gene for skin colour.
This means that the dominant gene is 'B' while the recessive gene is 'b'
A dominant gene is one that is exhibited phenotypically in the presence of both gene variants (heter0zygous state - Bb) while a recessive gene is only expressed phenotypically when it is in a h0m0zygous state (bb)
In order to find out the genotype of the parents, let us consider each cross one after the other.
1. A bright blue female and a bright blue male produce all blue progeny.
2. A yellow female and a yellow male produce a mix of both bright blue and yellow progeny
From statement 2, it can be deduced that the trait for yellow colour is dominant because a cross of the parents exhibiting this trait produces bright blue offsprings too, meaning that the genetic composition of the parents contains the gene that codes for yellow colour. Since these parents show a yellow colour in a heterozygous state, then the trait for yellow colour is dominant.
Therefore, the genotypes of the parents in each case include:
1. A bright blue female and a bright blue male produce all blue progeny. (bb × bb)
2. A yellow female and a yellow male produce a mix of both bright blue and yellow progeny (Bb × Bb)
