May return to the primary visual cortex
hope i helped ans warm wishes to you
Sexual reproduction is a process involving the fusion of two gametes to form a zygote. Gametes are special reproductive cells produced by meiosis. It produces genetically dissimilar offspring. Offspring may inherit beneficial qualities from both parents and there is a greater genetic variation in the offspring, leading to species that are better adapted to changes in the environment.
In a survey, it says that human's DNA are 99% the same.
Hope this helps! :)
the kt event set the stage for the Cenozoic era that began 65 million years ago however as the dinosaurs perished at the end of the cretaceous the mammals took the center stage. even as mammals increased in numbers and diversity, so did the birds, reptiles, fish, insects, trees, grasses, and other forms of life.
The resulting phenotypes are 75% flies with <em>red eyes, curly wings, brown body, and legs on the head </em><em>(R-C-B-L-) </em><em>and 25% </em>flies with<em> white eyes, normal wings, yellow body, and antennae on the head</em><em> (rrccbbll)</em><em>.</em>
<h3>Experiment</h3>
- In this experiment, we are performing a cross between two individuals that are heter0zyg0us for all the traits under study.
- Each trait is coded by a single diallelic gene.
- We will assume they assort independently and there is no interaction between them.
<h3>TRAITS</h3>
<h3>wing shape</h3>
- Dominant allele C codes for curly wings,
- Recessive allele c codes for normal wings
<h3>bodycolor</h3>
- Dominant allele B codes for brown
- Recessive allele b codes for yellow
<h3>antenna type</h3>
- Dominant allele L codes for legs on the head
- Recessive allele l codes forantennae on the head
<h3>eye color </h3>
- Dominant allele R codes for red eyes
- Recessive allele r codes for white eyes
<h3>Cross</h3>

- 1/4 = 25% of the progeny is expected to be RRCCBBLL, expressing <em>red eyes, curly wings, brown body, and legs on the head</em>
- 2/4 = 50% of the progeny is expected to be RrCcBbLl, expressing <em>red eyes, curly wings, brown body, and legs on the head</em>
- 1/4 = 25% of the progeny is expected to be rrbbccll, expressing <em>white eyes, normal wings, yellow body, and antennae on the head.</em>

The resulting phenotypes are:
- 3/4 = 75% flies with <em>red eyes, curly wings, brown body, and legs on the head.</em>
- <em>1/4 = 25% </em>flies with<em> white eyes, normal wings, yellow body, and antennae on the head.</em>
