I wanna say it’s the “ pulmonary veins” sorry if I get it wrong I’m in 9th grade but I’m more then correct that’s the answer
1) As blood groups A and B are equally dominant so the individual will express both characteristics in the phenotype.
Notice how in all the 3 other examples the organism is only expensive 1 version (allele) of each gene. For example the mouse with brown fur may have 2 brown fur alleles (and so would have to express this characteristic even if it was recessive) but it could have 1 allele which is less dominant than the brown, in which case brown would be expressed. In this case the alleles were not co-dominant.
Answer:
The limiting resource within an ecosystem determines the carrying capacity (indicated in ecology by the letter, “K”), which is the maximum number of individuals in a population that a habitat can support without environmental degradation.
Explanation:
Answer:
Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I.
Explanation:
When chromatids "cross over," homologous chromosomes trade pieces of genetic material, resulting in novel combinations of alleles, though the same genes are still present. Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I.
