The given question is incomplete as the group of choices lack the correct answer, however, the correct group of choices are as follows:

A. Movement of sister chromatids to opposite poles at anaphase II of meiosis.

B. Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.

C. Crossing over between homologous chromosomes during prophase I of meiosis.

D. Replication of chromosomes prior to meiosis.

E. Independent alignment of different homologous pairs on the metaphase I spindle.

The correct answer is : Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.

Explanation:

The Mendel's law of segregation says that during formation of gametes the copies of genes segregate from each other so each gamete has equal and only one allele of the gene.

This behavior of homologous chromosome can be seen in anaphase I in meiosis, responsible for the segregation of copies of allele into different copies.

Thus, the correct answer is : Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.

Answer from: Quest

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.

In a hypothetical breed of dogs, coat color is controlled by two genes. there are six different coat colors in this breed: black, brown, cream, gray, silver, and tan. consider the following crosses. cross 1: black females from a lineage of all black dogs are crossed with brown males from a lineage of all brown dogs. f1 males and females are all black. when f1 are intercrossed, f2 males and females are black or brown. cross 2: black females from a lineage of all black dogs are crossed with tan males from a lineage where all males are tan and all females are cream. f1 males are black, f1 females are gray. when f1 are intercrossed, f2 males and females are black, brown, gray, or tan. cross 3: silver females from a lineage where all females are silver and all males are gray are crossed with brown males from a lineage of all brown dogs. f1 males and females are all gray. when f1 are intercrossed, f2 males are black, brown, gray, or tan, f2 females are cream, gray, silver, or tan. select the correct statements regarding the mode of inheritance of the coat color genes. a) both genes are x-linked. b) both genes are autosomal. c) one of the genes modifies the expression of the other gene. d) each gene has an additive effect on the intensity of coat color. e) each gene independently specifies three colors. f) one of the genes is autosomal, and the other is x-linked.
