Autosomal chromosomes or autosomes are found in the body cell, but not sex cells.
Gametes are sex cells. They are sperm and egg.
Answer:
The fibularis longus
Explanation:
The fibularis longus starts at the top of the fibula and attaches to the first metatarsal bone of the foot.
It has two functions:
- Eversion of the ankle (turning the foot outwards)
- Plantarflexion (the movement like standing on tiptoe or depressing a gas pedal)
It's a pyramid of numbers, I believe.
Answer:
Alleles for feather colour exhibit incomplete dominance or co-dominance.
50% gray offspring + 50% black offspring
Explanation:
<em>It means that the alleles for feather colour in the hen exhibit incomplete dominance or co-dominance over one another.</em>
Assuming the allele for white colour is B, white colour will be b while the heterozygote Bb gives the gray phenotype.
Gray rooster + gray hen = 15 gray chicks, 6 black chicks and 8 white chicks.
15:6:8 is roughly 2:1:1 which is phenotypic ratio obtainable from crossing two heterozygous individuals as pointed out by Mendel.
Bb x Bb = 1BB, 2Bb, and 1bb
Crossing the gray rooster (Bb) with a black hen (bb):
Bb x bb = Bb, Bb, bb, and bb
= 2Bb (gray):2bb (black)
50% of the offspring will be gray while the remaining 50% will be black.
