3 blue, 1 white
Let blue be represented as B and white be represented as b
genotype of heterozygous blue plant: Bb
Cross = Bb x Bb
Possible genotypes of offspring: BB, Bb, Bb and bb
Thus, as can be seen, three of the four offsprings will be blue and one will be white.
hope this helps :^)
The question is incomplete. Complete question is as followed :
Imagine a human disorder that is inherited as a dominant, X-linked trait. How would the frequency of this disorder vary between males and females?
A. Males would display this disorder with greater frequency than females.
B. Males and females would display this disorder with equal frequency.
C. Females would display this disorder with greater frequency than males.
Answer:
C. Females would display this disorder with greater frequency than males.
Explanation:
Most of the X-linked disorders are recessive. but if it is dominant, a dominant gene is carried on the X chromosome. So it will effect all the females being the dominant and doesnot effect males more than females.
Hence option C. Females would display this disorder with greater frequency than males is the right answer.
Answer: A) Black trait is dominant
B) The genotypes of the parents must be Bb
Explanation: Let B represent the allele for black colour and b represent the allele for white colour. If the offspring between 2 black mice show the ratio of 3 black mice to 1 white mouse, it then means that the two parents are heterozygous for black colour, that is each of them have one allele for black colour (B) and one allele for white colour (b). They both have a genotype of Bb.
Bb x Bb = BB, Bb, Bb, and bb.
This means 1BB : 2Bb : 1bb
BB is black, Bb is black while bb is white which gives a ratio of 3 black mice to one white mouse. For Bb to manifest as black, it means that B is dominant to b.
<span>Fats are high energy molecules that assist in a growing organism. There is a lot of calories in fat that can be used for growth.When metabolising fat it produces carbon dioxide, water, and ATP. Sugars and/or starch is useful in the same method, they provide calories necessary for a seed or baby animal to grow. The starch can be cleaved into more managable sugars, and the sugars used in glycolysis and then the products of glycolysis used in the citric acid cycle. Used together an organism would have water from the fat that can be used to hydrolyze the sugars that it would consume to produce ATP.</span>
