Answer:
X-linked/Sex-linked recessive inheritance
Explanation:
<em>The most likely mode of inheritance of the trait is an X-linked recessive inheritance.</em>
The sex chromosome of a male is XY while that of a female is XX. The Y chromosome is hypothesized not to carry any allele ordinarily. Hence, a male child only needs to inherit one affected allele to become affected for recessive X-linked traits.
During gamete formation, the sex chromosome of the male segregates into X and Y gametes while that of the female segregates into X and X gametes. During fertilization, the X gamete of the male is usually inherited by the female while one of the X gametes of the female is usually inherited by the male.
<u>Assuming a father is affected for an X-linked recessive trait, the affected X chromosome will be passed to a female child and such a child would be a carrier, rather than being affected since she requires the two X chromosomes to be affected in order to exhibit the trait. </u>
<u>The affected X chromosome is thus passed to her male child according to the law of inheritance of the sex chromosome. Hence, the grandson of the affected man inherits the trait through the daughter of the affected man.</u>
Answer:
Exocytosis
Explanation:
exo meaning out, cyt meaning cell, so the whole word literally means cell out, or stuff taken out of the cell. This is also what secretion means
Answer:
In the given case, the two scientists are working on a barley plant, independently determined a short plant mutation, and thus, created homozygous recessive lines of short plants. The measurements of the normal tall plants' height in comparison to the mutant short plants were performed carefully, which showed that the two mutant lines were having similar height.
In order to test whether these two mutant lines are carrying mutation of similar genes or of the distinct genes, complementation test is performed. In the test, it was found that the tall nature is dominant over the short. The complementation test takes place when the two strains of the organism exhibiting different homozygous recessive mutations generate the same phenotype, which is mutant and is also generating the wild type offspring when mated or crossed because of recessive mutation.
Complementation will take place only when there is a mutation in different genes. In the given case because of the wild type offspring, a complementation test will take place showing mutation of distinct genes. When the two strains are identical, there will be no generation of wild-type offspring because of which complementation test will not take place.
