ONLY ANSWER IF YOURE AN EXPERIENCED FISH KEEPER<br> is my female swordtail pregnant?
LenKa [72]

Answer:

I don't know what your fish looks like but I will try my best :)

To accommodate the developing eggs, the mother's body expands, becoming deeper and broader. A few days before delivery, she develops a bulge below the gills, her outline becoming fairly square in this region, while the gravid spot has enlarged its area. The female swordtail and guppy will both give birth to anywhere from 20 to 100 live young after a gestation period of four to six weeks, and mollies will produce a brood of 20 to 60 live young after a gestation of six to 10 weeks.

Mendel determined that for a given character(i.e. pea seed shape) an individual has two factors that these can exist in two form
lions [1.4K]

Answer:

a. different alleles of the seed shape gene.

Explanation:

Mendel crossed different varieties of pea plants and he observed how phenotypic traits passed to the progeny. From these experiments, Mendel formulated the 'First Law of Segregation', where he observed that traits may exist in pairs that segregate (separate) at meiosis. During meiosis, i.e., gamete formation, these two factors separate from each other, thereby each gamete has the same probability of receiving either factor. Nowadays, we know that these two factors represent two different gene variants or 'alleles' for a given gene <em>locus</em>. Alleles can be classified into dominant or recessive as in the example above described, where the R factor (round) dominates on the r factor (wrinkled) to determine the seed shape.
