There is over 4,000 invasion species in America. Please specify.
Crossing two true breeding parents with opposite parents is the key:
Assume W is straight wing and w is curly.
Then you are crossing WW with ww
This will result in ALL Ww as offspring - so all straight offspring
If you then cross Ww x Ww you end up with a mix of
WW (1), Ww (2) and ww (1) - so a mix of straight and curly
Answer:
P generation has straight wings and curly wings
F1 has all straight wings
F2 has straight wings and curly wings
It is called the Epidermis. The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands.
This is the era of recent life that began about 66 million years ago and continues today. It includes the first appearance and Homo sapiens about 400,000 years ago. <span />
Explanation:
As we know that different versions of the gene are called as the alleles. Allele is the various sequence of DNA (deoxyribonucleic acid) or alleles are known to be different forms of the genes, which can be seen at the same locus on the homologous chromosomes. Let us know assume that gene Tyx has two alleles in it, which represents the two forms of expression having same character. i.e. Tallness and Dwarfness TT(tall), Tt(tall), tt(dwarf). In the given question, the version
(a) TT, where alleles exist in the homozygous dominant conditions,
(b) Tt, where alleles exist in the heterozygous dominant condition
(c) tt, where alleles exist in homozygous recessive condition. Therefore, it might follow autosomal dominant inheritance, or autosomal recessive inheritance or incomplete dominance etc.
