Answer:
Ben - Y Xc
Jen - XCXC
Violet - XCXc
Seraphina - XCXc
Samuel- Y Xc
Explanation:
Given -
Ben has a cleft chin
Let the allele for cleft chin be "c"
and the allele for normal chin be "C"
When Ben with cleft chin mates with wife Jennifer Garner having normal chin, then the two girl child do not have cleft chin but the boy has cleft chin.
This means that the allele C could be X -linked and the mother is not the carrier but the father is
The genotype of father Ben would be Y Xc
Genotype of mother would be XCXC
Genotype of two daughters XCXc , XCXc which means they are carrier for the next generation
Genotype of Boy - Y Xc
Answer:
B. An egg cell and a sperm cell unite.
Explanation:
Answer:
G-banding or Giemsa banding is a technique used to study the chromosomes by staining then at condensed stage. The visible karyotype can be used by this technique. The genetic diseases can be easily identified by this G banding technique.
The base composition of the genes (nucleotide) are stained by the dye known as Giemsa stain. The nitrogenous base adenine and thymine of the heterochromatic region of chromosome stained darkly in this technique. The darkly stained area is generally gene poor area.
