Skeletal muscle cells exhibit a phenomenon known as recruitment, in which the number of muscle cells recruited to contract is pr
Sergio039 [100]

Answer:

No, cardiac muscle tissue does not exhibit recruitment.

Explanation:

The cardiac muscle tissue does not recruit cells to contract. The reason is that the cardiac muscle contracts all its cells at once and with the same force. It does not have to recruit other cells since it does not have to lift objects of different weights. The heart's contraction aims to pump blood and to do it rhythmically. The heart has a natural peacemaker, the sinoatrial node. The Sinoatrial node transmits an electrical impulse to all the heart to contract it all at the same time and continuously. For these reasons, the cardiac muscle does not need recruitment.

in a 3-point cross, crossovers that occur during the formation of which gametes can be scored using the phenotype of f2 progeny?
JulsSmile [24]

In gametes generated by F1 tri-hybrids and gametes produced by parents from true-breeding populations.

When non-sister chromatids of homologous chromosomes exchange genetic material during meiosis, novel allelic combinations are created in the daughter cells. The locations of three genes in the genome of an organism are identified using a three-point cross. A homozygous recessive individual is crossed with a person who is heterozygous for three mutations, and the progeny's phenotypes are graded. When F1 progeny are self-pollinated, a 3:1 ratio of F2 progeny are created.
