Answers

Answer 1

Answer: Lancelets is the group of chordates that has a notochord and includes separate males and females.

Lancelet exhibits the four basic characteristics of phylum Chordata. It has a dorsal nerve, a notochord, a post annul tail, and pharyngiall gill slit.

Jawless fish, cartilaginous fish, and bony fish have notochord when they were still young but it was replaced by a vertebral column as they mature.

Lancelets are included in the subphylum cephalochordata. Cephalochordates are gonochoristics. It means that the sexes are separate. Both sperm and eggs cells are released in the water where fertilization occurs.

Why are women often carriers of X-linked traits but rarely affected by them?

Answers

Women have two x chromosomes, compared to men who have one x and one y chromosome. Because of the two x chromosomes, one of them can override the other. In men they only have one x and one y, they don't have the extra x chromosome to override the allele.

Women have two X chromosomes.Recessive alleles on one X chromosome are often masked by dominant alleles on the other chromosome.Women will not be affected unless they receive two recessive alleles.
