Answer:
None
Explanation:
Assuming the allele for height is T. Since dwarfism is autosomal dominant, a normal height person will be tt while a dwarf person will either be TT or Tt.
Hence, a man who is dwarf but has a normal height father will have a genotype of Tt and an average height woman will have a genotype of tt.
Tt x tt = 2Tt (dwarf), 2tt (normal height)
If the allele for vision is represented by B. A normal vision man will have the genotype while a colour blind woman will have the genotype .
x =
Since, colour blindness is X-linked and recessive, females need two alleles ( ) in order to be affected and none of their daughters posses two alleles.
Hence, none of their daughters is expected to be colour blind with achondroplasia.
It would have 18. Because using logic no one was born with only half of their chromosomes. When you think about it, Plant reproduction is basically like human reproduction. Hope i could help
Explanation:
The major event of Anaphase is the sister chromatids moving to opposite poles of the cells, due to the action of the condensing spindle fibres. The chromatids only start separating when the pressure is sufficient to split the centromere.
Answer:
By one week after conception, the multiplying cells have divided into outer cells enclosing a mass of inner cells. The inner cells will become the embryo.
Explanation:
By week one, the outer cells will give the trophoblast, which will later become the placenta, while the inner cells will form the embryoblast, which will become the embryo. Then the inner cells will be in one end, and in the other one, there would be the blastocele, which is a space with fluids. This process takes place in the fallopian tube and is part of the segmentation process.
