An organism has a haploid number of 20 what is the organisms diploid number
2 answers:
Answer:
Explanation:
The number of chromosome sets in a diploid is just the double of number of chromosomes in its haploid. For instance, if a haploid has “n” number of chromosome set, then a diploid will have “2n” of chromosome sets.
Here, the number of chromosome sets in haploid is equal to
Then the number of chromosome sets in diploid will be equal to
Hence, the organisms diploid number is

Answer:
The possible blood types of their children are: type AB (iAiB), type A (iAi), type B (iBi), type O (ii)
Explanation:
Blood type in humans is controlled by a gene with multiple alleles. Alleles iA and iB are dominant over allele i but co-dominant. The following blood types are encoded by the following alleles:
Blood type AB - iAiB
Blood type A - iAiA or iAi
Blood type B - iBiB or iBi
Blood type O - ii
According to this question, a man who has type B blood has children with a woman who has type A blood. They are both heterozygous, meaning that the man's genotype is "iBi" while the woman's genotype is "iAi". Both parents will produce gametes as follows:
iBi = iB and i
iAi = iA and I
Using these gametes in a punnet square (see attached image), the following possible blood types are produced in the offsprings:
- type AB (iAiB)
- type A (iAi)
- type B (iBi)
- type O (ii)
