Pleiotropy means that a single gene affects two or more characters. In the context of life history evolution, pleiotropy means that a single gene affects the fitness of the organism at two or more ages. It is convenient to categorize the combinations of age-specific pleiotropic effects as shown in Table 1.

Clusters of QTL for plant source capacity and seed traits may correspond to genes of metabolism having pleiotropic effects on source-sink relationships. When expressed during seed set, these genes may control the seed number and the NcotCel. When expressed during seed growth, they may control seed weight or seed protein content.

For the human sex chromosomes, males have A. two X-chromosomes. B. an X chromosome and a Y chromosome. C. two Y-chromosomes. D. only one chromosome—an X. B. one x and y. 47. Hemophilia is caused by a recessive allele found on the X chromosome.

Pleiotropic inheritance

Polygenetic Inheritance. Modification and inheritance of pleiotropic cross resistance and collateral sensitivity in Saccharomyces cerevisiae. Rank GH, Robertson AJ, Phillips KL. A meiotic segregant (oliPR1) was isolated with a phenotype of multiple cross resistance and collateral sensitivity. Alleles of pleiotropic genes are transmitted in the same way as alleles of genes that affect single traits. ________ inheritance can often be identified by complex inheritance patterns and … 2018-07-13 The pleiotropic gene may be lethal when one of its effects becomes the cause of the death of an individual.

A pleiotropic gene. A. Controls multiple traits in an individual. B. Is expressed only in primitive plants. C. Is a gene evolved during Pliocene.

Clusters of QTL for plant source capacity and seed traits may correspond to genes of metabolism having pleiotropic effects on source-sink relationships. When expressed during seed set, these genes may control the seed number and the NcotCel. When expressed during seed growth, they may control seed weight or seed protein content.

Inheritance of a pleiotropic mutation causing defects in metabolism of energy reserves, ethanol utilization and formation of cytochrome a.a3.

2 During this early period of genetic discovery, pleiotropy was considered to be quite rare because scientists assumed most genes only possessed a single function—a simplistic idea that remained popular throughout most of the 20th century.

MC1R, the gene which leads to the difference In 1902 Mendelian inheritance was demonstrated in poultry (by English geneticists William One gene may affect many traits (a condition termed pleiotropic). An example of pleiotropy, a person who inherits the mutated HBs gene will contract sickle-cell anemia, which damages erythrocytes, the spleen, and many other Correct Option -C single gene Explanation-When a single gene controls two or more different traits it is called pleiotropic genes and the inheritance is called Aug 17, 2020 Genetic pleiotropy, correlation among traits due to genes that possess Buzzell, R.V.H.
