The correct answer would be D. DNA evidence showing it was more closely related to mammals than to other vertebrates <span />
Answer:
Both heterozygous, with the trait for short hair being dom over the long hair
Explanation:
25% would be homzygous dominant, 25% homzygous recessive and 50% heterozygous
i think this is wrong but i tried
Variations, traits
Not all members of a species are the same. Every species exhibit variations. Traits, like eye color, are passed from parent to offspring.
Genetic variation is the subtle differences in the DNA sequence in each individual’s genomes. Genetic variation results in various forms or alleles of genes that determines distinct traits such as eye color, skin color, shape of face, and hair color that can be passed on from parents to offspring.
Answer: The blanks can be correctly filled up with prophase I and metaphase II.
Explanation:
In females, finite number of oocytes are present since birth. The process of oogenesis initiate in embryonic stage only. However, oogonia divide and mature to form primary oocytes. These primary oocytes start meiotic division but arrest in prophase I stage before birth.
After a girl attains puberty, one primary oocyte resumes its division each month during a menstrual cycle. The primary oocyte divides to form secondary oocyte and polar body.
Polar bodies degenerate after completing meiosis II. However, secondary oocyte halts its division again at metaphase II until fertilization takes place. Once fertilization takes place it completes its meiosis II and results into mature ovum and polar body.
