Answer:
Inherited genes and behaviors such as an unhealthy diet
Explanation:
I know this because its caused by family background and diabetes.
The modern taxonomists classified organisms on the general basis of evolutionary, morphological, and genetic traits
Explanation:
- Evolutionary relationships provides the phylogeny of evolutionary ancestors and descendants
- Homologous structures are structures which look the same but perform different functions
, like bones of a human leg compared to bones on a bird's wing
- Analogous structures have different structure but same function like an insect’s and a bird’s wing
- Embryo developmental pattern and similar relationships
- Similarities in DNA and protein sequencing in related organisms
The above basis provided modern taxonomists to classify organisms according to the various disciplines like Genetics, Cytology, Embryology, Physiology, Anatomy and many more.
Females produce egg cells, and males produce sperm cells. When a male's sperm cell meets a female's egg cell, the female becomes pregnant.
Jacksonville is mild to warm most of the year.
Answer:
The correct answer is option D) Albino = recessive, black = dominant.
Explanation:
- According to Mendel's Law of Dominance, of the two alleles which represent a gene, one can express itself even when in the presence of the other allele, that is in heterozygous state. This is called the Dominant allele. The other allele can express itself only in homozygous state. This is called the Recessive Allele.
- When a black guinea pig is crossed with an albino guinea pig, all black offspring (5) are obtained in the F1 generation.
- This indicates that the Black colour is dominant over the albino colour, as it masks the expressions of the albino phenotype.
- This also indicates that the genotype of the parent black guinea pig is homozygous dominant, as if it would have been heterozygous dominant then in the F1 generation there was a chance of formation of both black and albino offspring in 1 : 1 ratio.
- When a black guinea pig from the F1 generation is crossed with the albino guinea pig it gives both black (4) and albino (3) guinea pigs, roughly in the 1 : 1 ratio.
- This indicates that black guinea pig from the F1 generation was heterozygous dominant. This is why the recessive allele giving rise to the albino phenotype could express itself in the second cross.
- The second cross between F1 offspring and recessive parent is called the Test Cross.
