Answer:
None
Explanation:
Assuming the allele for height is T. Since dwarfism is autosomal dominant, a normal height person will be tt while a dwarf person will either be TT or Tt.
Hence, a man who is dwarf but has a normal height father will have a genotype of Tt and an average height woman will have a genotype of tt.
Tt x tt = 2Tt (dwarf), 2tt (normal height)
If the allele for vision is represented by B. A normal vision man will have the genotype while a colour blind woman will have the genotype .
x =
Since, colour blindness is X-linked and recessive, females need two alleles ( ) in order to be affected and none of their daughters posses two alleles.
Hence, none of their daughters is expected to be colour blind with achondroplasia.
Answer:
a. An intoxication
Explanation:
Intoxication occurs when a toxic substance comes into contact with an organism and causes a number of adverse effects, affecting its homeostasis, disrupting the organic balance.
When a person or animal eats a food contaminated mainly with bacteria, a number of unpleasant symptoms are triggered by the body due to the poisoning caused by some substance released by the bacteria. Usually people associate the infection with spoiled / spoiled foods, but often they can eat contaminated, good-looking foods.
This is the case of intoxication caused by V. parahavmolyticus. Food contaminated by this bacterium has no change in color, taste or smell. When someone eats food contaminated with V. parahavmolyticus, they ingest a toxin produced by this bacterium. This illness is referred to as food intoxication.
It's <span>meiotic prophase I.</span><span>
</span>
Explanation:
true for meiosis :-
d) It produces haploid cells.
Because meiosis is also called reductional division as it divides the chromosome no. into half .
<span>The scientific view's order of Earth's first living things to the most recent is described by choice C. cyanobacteria, hagfish, crocodilians, giant ground sloths. Cyanobacteria have lived on the Earth since the Precambrian supereon. Actually, they first appeared in the Archean eon (4-2.5 billion years ago). Hagfish, as other jawless fish, appeared in the Paleozoic era (541-252 million years ago). Crocodilians appeared in the Cretaceous period (145-66 million years ago). Giant ground sloths, also known as megatherium, appeared in the Pliocene epoch (5.33-2.58 million years ago).</span>
