The best answer to the question above would be the first statement. Cardiorespiratory endurance affects physical fitness in such a way that it increases the efficiency with which the body delivers oxygen and nutrients to its cells.
Answer:
Explanation:
I am not that sure but according to me it will be the option 3.
<span> COMPLETE DOMINANCE:
</span>
<span>Mendel concluded that some alleles are dominant and others are recessive. When one dominant allele is present, it's enough to make the recessive allele unexpressed (this is what happens in heterozygous individuals). In other words, it 'hides' or masks the recessive allele.
CO-DOMINANCE:
-a condition in which both alleles are dominant.
</span>
There are alleles that have the capacity of dominating at the same time, and when an organism is heterozygotic, both alleles are expressed.
For example, a white chicken(WW) crossed with a black chicken (BB): 100% of the offspring being WB. With this genotype, they have black feathers and white feathers.
It's not a blend of colors, but a case where both are expressing.
INCOMPLETE DOMINANCE:
-a condition with none of the alleles is dominant or recessive, so the traits blend in the phenotype.
Some alleles are not completely dominant, and when that's the case the phenotype of a heterozygous organism will be a mix between the phenotypes of its homozygous parents.
For example:
plant 1: RR -red
plant 2: rr- white
By crossing this plants we will obtain 100% of the offspring with a color mix: pink.(genotype: Rr)
Red and white are not completely dominating so it results in a blend of colors.
SEX LINKED TRAITS
Sex chromosomes contain genes that determine the sex of a person. Two X chromosomes result in a female and one X plus a Y result in a male.
In those chromosomes, there are genes specific for each gender, and in those chromosomes, there are genes that code for certain traits- the sex-linked traits.
These traits will be inherited according to the sex chromosomes they receive from their parents.
Ozone protects the Earth from harmful UV rays from the Sun.
Answer:
See below.
Explanation:
Let the allele for colour be C (c) and the allele for shape be S (s).
True breeding yellow plant with round seed = CCSS
True breeding green plant with wrinkled seed = ccss
crossing the two;
CCSS x ccss = CcSs (yellow colour with round seeds)
All the F1 offspring are yellow with round seeds (CcSs).
Selfing CcSs to produce F2 generation results in:
9 Yellow, round seeded
3 Yellow, wrinkle seeded
3 Green, round seeded
1 Green, wrinkle seeded.
<em>The inheritance pattern of the two traits follow the law of independent assortment of genes as described by Mendel 2nd law of genetics. Medel stated that characters are inherited independently of one another.</em>
