Answer: D.
Explanation:
Dizygotic twins are formed due to the fertilisation of two eggs by two sperms which get implanted in the uterus and develops two fetuses, that s why they have 50% of genes in common. whereas monozygotic twins form from a single fertilized egg that splits and so they have 100% of their genes in common.
Hence, the correct statement is D.
Answer:
The correct answer is b. all tall
Explanation:
If the genotype of one parent for height is Tt and another parent is TT then after the fusion of gamete all the offspring will show tall phenotype because all the offspring will have at least one allele of tall character.
T t
T TT Tt
T TT Tt
So after cross two phenotype would be homozygous dominant for tall character and the other two will be heterozygous dominant for tall character. Therefore all the offspring would be tall.
