The birth and reproduction of Carrier(Heterozygous) organisms, (i.e) heterozygous individuals that have a dominant allele masking the effects of the recessive 'lethal gene.' However even though the gene is masked, it is still there. Therefore, if the heterozygous individual is to reproduce with another heterozygous (carrier) organism there is a higher chance that their offspring will have the active form of the 'lethal gene' causing the death of the offspring.
Answer:
The genotype of male with red-green color blindness is XY, X chromosome possessing recessive allele of gene responsible for differentiating red-green color.
Explanation:
Color blindness is sex-linked trait and its inheritance follows criss-cross pattern. Dominant gene of allelomorpihc pair enables a person to differentiate between red and green color.
The genotype of male and female are different for the pair of sex chromosomes. Male is hetero-zygous (XY) and female is homo-zygous (XX). The gene controlling this trait is present on X chromosome.

Blubber is used by polar bears to maintain internal homeostasis in cold temperatures.
Step-by- step Explanation:
- Since the percentge is gradually decreasing a point will come when it will be Zero. Therefore number of trophic level is limited and typically less than 10.
- If we properly look at the pattern 100%>10%>1%>0.1%. We observe that, only ten percent of available energy is transferred from one trophic level to the next.
- Now, if we look at the structure of the model, The box representing the primary consumer is larger than the boxes representing other consumers Thus, we can conclude that, Among the consumers in the ecosystem, first level consumer have the most available energy.
Thus , sclaims B,C and D supported by the model.
