Answer:
The right answers are: XAXA and XAXa
Explanation:
A genetic disease is caused by an X-linked recessive inheritance when:
1. the gene present on the x linked chromosome, involved in the mutation.
2. The presence of both mutant alleles is necessary for the disease to be expressed in a female.
As per the image, the mother has always transferred a healthy allele (XA) so the answers are the genotypes carrying this allele.
Thus, the right answers are: XAXA and XAXa
A refined understanding of the paleoenvironmental history recorded at the okanagan centre section, an mis 4 stratotype, south-central british columbia, canada

<u>Abstract of this paper is </u>
The Okanagan Centre phase is the stratotype for marine oxygen isotope stage (MIS) four sediments (Okanagan Centre go with the flow) within the southern indoors of British Columbia, Canada. preceding work advised that those sediments report glacial and two interglacial cycles. This observe reports on particular sedimentological and geochronological investigations of lithostratigraphic units comprising the Okanagan Centre sequence, revealing successive deposition of subaqueous and subaerial outwash, a subglacial till and glaciolacustrine sediments at some point of MIS four. A limiting optical age of 113 ± 8 ka defines the base of this sequence. Sedimentological, paleopedological, optical courting and tephrochronological statistics from sediments near the middle of the series screen soil development (MIS three) in eolian sediments deposited on a river terrace overlying a deglaciated floor. within these sediments.

By the process of diffusion, the glucose molecules outside the cell will begin to move through the membrane to inside of the cell because in diffusion, molecules move from high concentration to low concentration.
OR
Glucose molecules will diffuse out of the cell.
Answer:
interfere with carbohydrate digestion in the mouth..
Explanation:
A blockage of the ducts from the parotid glands would interfere with carbohydrate digestion in the mouth.
Answer:
The correct answer is option D.
Explanation:
Linkage mapping is the mapping process in which the genes present on the chromosomes are mapped on the base of their linkage. The linkage mapping helps in calculating how frequent recombination occurs using testcross.
Linkage mapping does not utilize the information that is on DNA sequences, however, it helps in assuming the distance of two linked genes is proportional of the recombination frequency. By the recombination, frequency mutations can be found and study.
Thus, the correct answer is option D.
