Biology
1 answer:
Svetlanka [38]2 years ago
5 0

Answer:

DNA replication

Explanation:

For the most part of a cell's cycle, each chromosome has only one chromatid.

Before entering meiosis, a diploid cell (which contains a set of chromosomes from one parent and another set from the other parent) first doubles its DNA, and the cell will start division with each chromosome having 2 sister chromatids.

During meiosis I homologous chromosomes (the maternal and paternal sets) separate, and during meiosis II the sister chromatids separate. As a result, 4 daughter cells with half the original diploid chromosome number and one chromatid per chromosome are produced.

Purple flowers are dominant to white flowers. A heterozygous purple flower is crossed with a white flower. What are the probabil
Zanzabum

Answer:

50% probability of Pp (purple) or pp (white) genotype.

Explanation:

P = purple gene

p = white gene

Punnet squares show the possible genotypes and probabilities of each genotype in the offspring of a cross:

Purple flower genotype (heterozygous) = Pp

White flower genotype = pp

Punnet Square:

\left[\begin{array}{ccc}&P&p\\p&Pp&pp\\p&Pp&pp\end{array}\right]

Potential genotypes for offspring are Pp and pp;

According to the Punnett square, 2 of 4 offspring will have the Pp genotype and the other 2 will have pp genotypes;

This means 2 should be purple and 2 white;

Or, there is a 50% chance of having either genotype, of being purple or white.
