no. a person cannot be carrier of a dominant genetic disorder. if a certain disorder is a result of dominant gene both the homozygous and heterozygous individuals are sick and no one of them is carrier. The carrier state is seen only in a situation where genetic disorder is expressed when individuals inherits recessive alleles each from each parent. for someone to be a carrier in this situation, he/she must be heterozygous for certain disorder that is only expressed when an individuals is homozygous of recessive allelles.
Angiosperms do not have cones like gymnosperms, instead, they have flowers and the ovule is protected by the carpel which after fertilisation forms the seed. The similarity between angiosperms and gymnosperms is that both have leaves, stem and roots.
Answer:
Option A, The lymphocytes express antigens specific for the antibodies in the assay
Explanation:
The options for the question are
a) The lymphocytes express antigens specific for the antibodies in the assay
b) The lymphocytes do not have antigens specific for the antibodies in the assay
c) This is not a valid method for identifying HLA agents.
Solution -
The aim of conducting this assay is to use the ability of the microlymphocytotoxicity assay (CdL) to detect the antibodies specific to the antigens based on the complement dependent assay.
The B and T lymphocytes are tested at both warm and cold temperatures and then the result obtained is compared with other non –complement based test results. HLA-ABC alloantibodies are weak in reactivity and specific to B cell hence they can be identified only through the CdL assay.
Hence, option A is correct
