Answer:
The correct answer would be - 25%.
Explanation:
It is given that the Blue flower is dominant over the yellow flower which means Blue is represented by allele B here and allele b for yellow and Bb is a heterozygous case with a blue phenotypic character. Similarly, the Tall plant is dominant over short and represented by T and t respectively.
BbTt is a heterozygous condition and a cross with itself will produce :
Gametes: BT Bt bT and bt
BT Bt bT bt
BT BBTT BBTt BbTT BbTt
Bt BBTt BBtt BbTt Bbtt
bT BbTT BbTt bbTT bbTt
bt BbTt Bbtt bbTt bbtt
Here 4 out of 16 offspring are heterozygous for both traits represented by bold alphabets. Therefore the correct answer is 25%
Answer:
The purpose of the carbon cycle is to utilize the carbon by the organisms such as plant which uses carbon in the form of carbondioxide for making food. This carbon is stored in the form of glucose. When this food is eaten by the animals, it is broken down into simpler substances and carbondioxode is released in the atmosphere again.
Some carbon is present in soil which is used by microorganisms such as bacteria. So carbon cycle is very important for the survival of life on earth.
The answer to this question may be the second one," Mitosis produces two genetically identical daughter cells but meiosis produces four genetically different daughter cells."
