atch the statement to the following options.A. One of a pair of chromosomes with similar genetic information and from different
Goryan [66]

Answer:

A. Homologue.

B. Chiasma.

C. Synaptonemal.

D. Synaptonemal.

E. Synapsis.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

Synaptonemal complex can be defined as a network of proteins that is responsible for holding homologous chromosomes (homologues) together.

Generally, a synaptonemal complex (protein lattice) is formed between homologous chromosomes during mitosis and meiosis. Also, synaptonemal complex is important for the formation of the four sister chromatids referred to as tetrads.

Furthermore, the synaptonemal complex (protein lattice) has a tripartite structure which comprises of the following components;

I. SC protein-1 (SYCP1).

II. SC protein-2 (SYCP2).

III. SC protein-3 (SYCP3).

In conclusion, the synaptonemal complex plays a significant role in synapsis, recombination and chromosome pairing.

Matching the various terminologies in genetics with their description, we have;

A. Homologue: one of a pair of chromosomes with similar genetic information and from different sources like the sperm and egg.

B. Chiasma: several X-shaped structures may be visible under the microscope and indicate where crossing over has occurred.

C. Synaptonemal: a lattice of protein holds two replicated chromosomes in precise register with one another.

D. Synaptonemal: four chromatids are held together by a zipper-like structure.

E. Synapsis: a process in which pairs of homologous complex chromosomes line up side by side.

In sweet pea, red flower color is controlled by two genes involved in the anthocyanin pathway, A and B. Both genes are required
Alex787 [66]

Answer:

The dihybrid ratio we expect in the offspring is 9:7.

Explanation:

This is an example of complementary gene interaction, which is the non allelic interaction or genes, where the prominent genes at heterozygous loci may complement each other by complementing recessive alleles at the respective loci.

So in this case of  complementary gene interaction, the individuals that are A-bb or aaB- or aabb will have the same set of observable features (phenotype) but only A-B- individuals will how the dominant phenotype.
