Genetic homology and crossing over in the X and Y chromosomes of mammals

Human Genetics, 1982
The "X-Y crossover model" described in this paper postulates the (1) the pairing observed between the X and the Y chromosome at zygotene is a consequence of genetic homology, (2) there is a single obligatory crossover between the X and Y pacing segments, and (3) the segment of the X which pairs with the Y is protected from subsequent inactivation ...

Unequal crossing over at the rRNA locus as a source of quantitative genetic variation

Nature, 1978
MUTATIONS, in the broad sense, are the source of genetic variation for evolutionary change, whether through the agency of natural or artificial selection. The contributions of new mutations to genetic variation in artificial selection lines are thought to be small, as estimates of the rate of generation of new genetic variation by mutation have been ...

Evidence for separate genetic control of crossing over and chiasma maintenance in maize

Chromosoma, 1978
The meiotic cytological behavior of chromosomes in maize microsporocytes homozygous for the recessive mutant desynaptic was studied at various stages. It was found that following apparently normal pachytene synapsis there appears to be sporadic precocious desynapsis.

Metaphase I bonds, crossing-over frequency, and genetic length of specific chromosome arms of rye

Chromosoma, 1979
Using a Giemsa C-banding procedure three chromosome pairs (3, 6 and 7) have been identified in meiosis of the F1 of a cross between two rye inbred lines. Two of these chromosome pairs (3 and 7) were heterozygous for a prominent telomeric heterochromatic band. The comparison between the frequencies of the different meiotic configurations at metaphase I,

Crossing Over

Right Here, Right Now, 2021
Crossing over is the swapping of genetic material that occurs in the germ line. During the formation of egg and sperm cells, also known as meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross ...

Population genetics of unequal crossing over

Journal of Molecular Evolution, 1975
The population genetics of unequal crossing over was examined for an infinite population with random mating. The following cases were considered: 1. There is an initial portion of duplicated genes which offer the opportunity for unequal crossing over, but the primary event leading to the duplication does not occur any more (model 1a). 2.

Genetic improvement of oysters: Current status, challenges, and prospects

Reviews in Aquaculture, 2023
Oysters are one of the most commercially important shellfish species and have been cultured for thousands of years. Oyster aquaculture supports the major aquaculture industries in many countries.

Performance analysis of permutation cross—over genetic operators

Journal of Decision Systems, 1996
ABSTRACT We are interested here in the utilization of Genetic Algorithms (GA) as approximation methods for combinatorial optimization. They are stochastic methods using genetic operators on a population. For their design, two points must be worked: the general scheme of the algorithm with parameter adjustment and the design of chromosome contents and ...
