ploidy

The number of copies of the set of chromosomes in a cell. A normal diploid cell with two copies has a ploidy of two; a haploid cell with one copy, such as an ovum or a spermatozoon, has a ploidy of one.

ploidy

the number of chromosome sets making up the total genome of an organism.

Thus the ploidy of normal humans is two and is written 2n. See DIPLOID (1).

When contrasting the mean numbers of males and females between ploidies, no significant differences were found for Bacorehuis, but significant differences were found at Rancho Bueno and Ceuta, where on the average, more males were present within triploids than diploids (Fig.
The observed growth (body weight) between culture sites for both ploidies followed a pattern of best growth occurring within the site with the highest ACH L-a: ATD ratio and the least growth occurred at the site with the lowest ACHL-a:ATD ratio.
In the present work, fecundity was used as a measure of reproductive output to compare both ploidies and culture sites.
9), and the lack of a significant interaction between ploidies and culture months indicating that similar proportions of males and females occurred for diploids and triploids during the culture months, we propose that more than one gametogenic cycle occurred at both tropical sites, Bacorehuis and Ceuta.
Mortality was found to be similar between the 2 ploidies in S.
virginica exhibit a clear advantage over diploids even when both ploidies are disease resistant, as observed previously in S.
The results of Harding (2007) could be explained by the lack of measurements on smaller oysters combined with large differences in initial size between ploidies, taking into account that the most rapid growth is observed during the first 2 y of life (Kraeuter et al.
