Answer:
The respiratory system brings oxygen unto the lungs, while the circulatory system delivers oxygen throughout the body.
Explanation:
Answer:
The correct genotype of the two pure lines and the F1 is:
A⁺A⁺B⁰B⁰C⁰C⁰D⁰D⁰ and A⁰A⁰B⁺B⁺C⁺C⁺D⁺D⁺
The number of additive alleles on each genotype are two and six respectively.
Explanation:
Locus( plural form . loci) are fixed point on a chromosome in which genes are located. These genes are specific genetic material or genotype.
Now;
If we decide to designate the allele of the four loci into either additive (⁺) or non-additive(⁰); we have the following :
Let's the allele of the four loci to be
A⁺/A⁰, B⁺/B⁰, C⁺/C⁰ and D⁺/D⁰
However, from the diagram below; we deduce that the correct genotype for the two pure lines and the F1 is as follows:
A⁺A⁺B⁰B⁰C⁰C⁰D⁰D⁰ and A⁰A⁰B⁺B⁺C⁺C⁺D⁺D⁺ and the number of additive alleles on each genotype are two and six respectively.
The cross between both F1 traits will yield an heterozygous individual for the offspring. i.e A⁺A⁰B⁺B⁰C⁺C⁰D⁺D⁰ with only four additive allele
Answer:
Alleles.
Explanation:
Gene may be defined as the functional segment of DNA that codes for the particular protein. Genes are responsible for the phenotype and genotype of the organism. Each gene may exist in multiple forms.
The variants forms of the genes are known as alleles. Alleles are the alternative form of the same gene. A single gene may have atleast two alternative form. These alternative forms together contribute the functional aspect of the organism.
Thus, the correct answer is alleles.
All of these industries would be the correct answer
<h3><u>Answer;</u></h3>
<u>Latitude</u>
The principal characteristic that differentiates temperate and tropical rain-forests is <u>latitude.</u>
<h3><u>Explanation;</u></h3>
- There are two types of rain-forests, namely, the tropical rain-forests and the temperate rain-forests. These two types share some similarities such as being rich in plant and animals species with a greater diversity in tropical rain forest.
- However they differ in a number of ways; tropical rain-forests are warm and moist; while temperate rain-forests are cool.
- <u><em>Tropical rain-forest, forested areas must: Lie between the Tropic of Cancer and the Tropic of Capricorn, receive rainfall regularly throughout the year, remain frost and free through out the year with little fluctuations.</em></u>
