1 answer:

3 0

Nervous system is the organ system that is mostly responsible for generating behavior in multicellular animals. The nervous system coordinates multicellular animal’s behavior and transmits signals within the body. Specific excitatory and inhibitory substances are produced by the nerve cells for them to interact with each other and certain chemicals, sound and light is detected by the sense organs such as ear and nose which control the behavior and movement of multi cellular animals in their environment.

Why must meiosis and not mitosis be used to produce gametes?

Inga [223]

This is because meiosis divide the total chromosomes number by half its original number (2n/2 = n) which would be combined with the haploid egg cell to produce a diploid (2n) zygote white mitosis maintains the chromosome number.

A heterozygous round seeded plant (Rr) is crossed with a homozygous round seeded plant (RR).

igomit [66]

So I don’t see answer choices here, but your answer is 50% of the offspring will be homozygous dominant with RR, and 100% of them will carry a homozygous dominant gene of Rr

If you take the two sets and put them into a punnett square, it would look like this (image attached):

When the two sets of alleles are crossed, you would end up with half of your pairs being fully dominant (RR), and the other half being dominant while containing a recessive gene (Rr). Since there’s only one recessive gene in these pairs, it gets overridden and the pair itself is dominant.

So your answer is 50% will be homozygous dominant with RR!
