Answer:
1:1:1:1 walnut comb
Explanation:
If a cross is made between a female who is RRpp (rose comb) and a male who is rrPP (pea comb) then:
P: RRpp x rrPP
F1: RrPp RrPp RrPp RrPp
This means that all of the offspring in F1 generation will have heterozygous genotype (at both loci). Since it contains both dominant alleles, the phenotype is walnut comb.
Less genetic variation in the inheritance of traits causes a crops ability to be more prone to disease because there are less alleles immune to disease in the genetic pool
Anatomy is the study of human body parts, while physiology is the study of the functions of said body part. So anatomy is what the body part is, and physiology is what that body part does.
Dna extration from a onion and from a cauliflower would be different because even though all DNA is composed by the same nucleotides (A, T, C and G), the sequence of their genes will be different. That difference is why a cauliflower doesn't look like a onion. The cauliflower has genes that, when expressed, make the organism look like cauliflower and nothing else..

Protective membranous coverings that lie between bony coverings and the soft tissues of the cns are called the <u>meninges</u>
<h3>What are the brain meninges?</h3>
The brain meninges are the three protective membranous thin layers of tissue that cover and protect the brain and spinal cord of the nervous system. These meninges are:
- The dura mater
- Arachnoid mater
- Pia mater
So therefore, the protective membranous coverings that lie between bony coverings and the soft tissues of the cns are called the meninges
